Video summary
In a comprehensive analysis of 425,000 people in England spanning four centuries, economist Gregory Clark challenges conventional beliefs about social mobility by arguing that genetic transmission plays a far more significant role than cultural or environmental factors. Using genealogical data from the Guild of One Name Studies and parish records dating back to the 17th century, Clark demonstrates that the correlation between parents' and children's social status has remained remarkably stable over time, showing no increase in mobility despite major societal changes like industrialization and expanded education. The study reveals a simple genetic model where outcomes are predicted primarily by how many genes individuals share with their ancestors; for instance, mothers and fathers exert exactly equal influence on non-wealth outcomes because genetics is transmitted equally from both parents, whereas wealth inheritance follows patrilineal patterns due to historical practices of male-dominated property transmission. The research further dismantles the myth that birth order or family size significantly impacts social success for the vast majority of people. Clark's data shows that firstborn children do not consistently outperform younger siblings in education or occupation across 99% of families, and variations in parental attention due to larger family sizes have negligible effects on outcomes except regarding wealth division among heirs. Even more strikingly, individuals' life chances remain correlated with their parents regardless of whether they lived together; the study found that children whose fathers died before age ten showed no difference in social outcomes compared to those who knew their fathers throughout childhood. This suggests that genetic predispositions operate independently of direct parental interaction or specific environmental nurturing during upbringing. Clark's findings have sparked intense ideological controversy, particularly within academic circles where his work is often dismissed as "pseudoscience" or linked to eugenics despite the absence of any advocacy for selective breeding in his research. The backlash was notably evident when a talk at Glasgow University regarding his paper titled *For Whom the Bell Curve Tolls* faced cancellation due to faculty petitions, though university administrators ultimately allowed it under enhanced security measures after changing only the title slightly. Critics argue that acknowledging genetic influences undermines meritocratic ideals and suggests social policies like universal education are ineffective; however, Clark counters that societies have vastly over-invested in schooling based on this illusion of mobility, citing evidence from UK compulsory school age extensions showing no corresponding improvements in income or longevity for additional years of education. The implications extend to broader societal dynamics including immigration patterns and demographic shifts. Historical examples like the Huguenot refugees who rapidly assimilated into England's upper class within a few generations illustrate how high-status genetic lineages can persistently influence social outcomes over centuries, while lower-status groups may take longer periods for their descendants to rise or fall according to regression toward the mean. Clark notes that modern fertility trends show slight "dysgenic" tendencies where individuals with lower educational potential have marginally more children than those with higher potential, though this effect is minimal compared to historical shifts after the Industrial Revolution when upper-class fecundity dropped dramatically. He also highlights how physical attractiveness in economists correlates with publication success, suggesting it may serve as another imperfect indicator of underlying social competence rather than mere bias. Ultimately, Clark proposes a pragmatic approach to reconciling genetic determinism with personal agency: while genetics sets initial parameters like cognitive potential or personality traits through mechanisms akin to thermodynamics creating predictable societal trends, randomness and individual choices still allow for significant variation within families. He advises parents against obsessing over optimal child-rearing practices since outcomes largely follow predetermined trajectories regardless of parenting efforts, suggesting instead that society should focus on enjoying children rather than attempting to engineer their futures. The study concludes that while genetics explains much about intergenerational transmission of status, it does not preclude individual effort from making meaningful differences within the constraints imposed by biological inheritance and statistical probabilities.

What's this new paper of yours about the
inheritance of social status?
So the paper looks at 425,000
people in England over the course of 400
years who are all linked together by
descent and marriage
and just asks what describes
how you inherit social status.
And it ends up that there are actually
three very interesting aspects. One is
that there's a very strong inheritance
of status, much stronger than people
conventionally believe. And so there's
an underlying correlation that's really
strong.
The second astonishing aspect is that
that correlation hasn't changed over the
course of 400 years. There's no more
social mobility now than there was in
the 17th century, the 18th century, the
19th century.
But the most surprising element of all
is that if you want to predict how
correlated people will be
then that prediction is based on what's
their genetic correlation. And so the
data is just very consistent with a
really simple model of genetic
transmission
where what just matters is how many how
many genes do we have in common and
that'll explain how much outcome we'll
have in common.
Uh and uh
that as I say is for many people very
surprising and also quite troubling for
a lot of people. What is the methodology
of you being able to track genetics
across such a long period of time? How
how are you able to do that? Presumably
ancestry.com wasn't tracking people 400
years ago. Right. Um so the lineage
stuff is is fine. And so basically I was
using there there are all these kind of
interesting societies in Britain and one
is the Guild of One Name Studies.
And these are two or 3,000 people who've
devoted themselves to following the
history of particular surnames in
England. And they've done fantastic jobs
kind of actually tracking people's
genealogy over hundreds of years.
And so
that part is is is straightforward. But
the only thing we can do here is we
don't have we have no direct genetic
evidence here.
What we can look at though is what would
be the predictions of a genetic model of
transmission.
And that has a distinctive and very
clear set of predictions about how
correlated fourth cousins, third
cousins, second cousins, first cousins
will be.
Uh and and it all depends on how much
assortment there is in marriage, how
strong these correlations will remain.
And so there's also, you know,
predictions about siblings, about
grandparents grandchildren.
And as I say the the very surprising
thing here is that the predictions of
that model are very consistent with this
data for England. Uh and it it really is
uh you know, so as I say so so there's
nothing conclusive here, there's nothing
direct. But there is just a very
interesting empirical pattern.
And then as part of the paper
I also can say, well what about other
features of inheritance of status that
would be consistent with genetic
transmission? Do they also hold? And so
here's one example is
with genetic transmission mothers should
always have an equal influence as
fathers in terms of outcomes for
children.
Because you get half of your genetics
from each parent.
Now if we go back to 19th century
England fathers play a very different
social role than they do now.
If you look now mothers still actually
spend much more time with children than
do fathers.
And so we would actually expect with
social transmission that maybe sometimes
fathers are more important and other
times mothers are much more important.
But the data for this lineage in England
is very clear. If you want to predict
children's outcomes mothers and fathers
play exactly the same weight.
And and you know, one so early on we
have evidence on the literacy of mothers
and fathers and so that's equally
predictive of what the child literacy
would be and it doesn't matter if it's a
boy or a girl.
In in those cases it's again equally
predictive.
For other outcomes like occupation
we don't have occupations for women in
the 19th century.
But we can proxy women's occupations by
for example taking their brother and
then taking their husband's brother.
And that'll actually give us a good
proxy for what their occupational status
is and then we can say which predicts
child outcomes better. Is it the
mother's proxy or the father's proxy?
And the answer again is no, it's exactly
the same weight.
And so and that's true as I say all the
way through the last 300 years that
mothers and fathers play exactly the
same role in terms of outcomes except
for one important outcome.
And that outcome is
wealth.
For wealth fathers are much much more
influential than mothers.
And that's because wealth tended in
England to flow on the patriline.
That men inherited more family wealth
than women did. And so what matters is
what your grandfather's wealth on the
patriline as opposed to your grandfather
on on the matriline. So as I say it's
there's this this is one piece of
interesting ancillary evidence. A second
piece
is
what's the effect of birth order on
outcome?
Right? And in the social world, I mean I
don't know if you have children, I had
three.
And the oldest child gets much much more
parental attention than the younger ones
do, right? And talk to anyone who has
children and this is true. I mean the
parents are new thing when the first kid
comes along. The parents have all these
ideas about how they're going to shape
these kids.
And so and and empirically we know that
older children get more attention than
younger children.
So you might expect that older children
will do much better in terms of social
outcomes.
Uh it turns out in this data no,
it's
in almost every case
birth order doesn't matter.
Your chances in life are the same
whether you're first or the last. And a
lot of the families in the 19th century
there are 10 children.
And so you would think the 10th one is
coming into this kind of crowded family,
there's no more space.
My own parents were both from families
of 12.
And by the time, you know, my father and
mother, I think we both were number
nine. By the time they came along the
housing's incredibly tight. You're
sharing a bed with three siblings and
stuff like that.
And
but it turns out it it it it doesn't
matter except
again there's a slight exception for the
top 1% of families in the 19th century,
the kind of elite
the oldest son
is doing better than the younger sons.
But that's the only thing that matters.
So the old and the older son inherits
more but is also more likely to be sent
to university than the younger sons. So
you do see slight deviations for this.
But for 99% of the population
it doesn't matter what birth order is.
And then another thing you can look at
is what about family size? Isn't that
going to influence your outcomes?
Because the more children there are, the
less resources there are, the less
parental attention.
Again
in the era so there's an era up to
marriages of around about 1880
where
in England family size was random.
People made no attempt to control
fertility. And it is amazing but they
just apparently got married, produced
children. Sometimes there's only one
child.
You know, just the accidents of
fertility.
In the sample we have there's one guy
who has 27 children
from two different wives.
And so you get this enormous variation
in family size. And again
it has no effect except for richer
families for wealth.
And then if you're from a larger family
then your wealth actually declines.
Right? And so if you're from a wealthy
family and it's larger your wealth
declines because the wealth has to get
divided.
Yeah, the if if inheritance is going to
play a large role in determining your
future level of wealth and there are
more people taking from that pie each
sliver of the pie is smaller. Yeah,
right. So so as I said so that's another
aspect. Uh another thing we can look at
is
do you ever need to meet your parents
for them to influence your social
outcomes?
And so in a lot of the period that we're
looking at, you know, parental death is
occurring at relatively early ages for
some people in their 50s, 60s. And so
about 10% of the kids their father dies
before they're 10 years old.
And we can then say how correlated are
you with your father
as a function of
you know, you you knew them all the way
up to your 21 or they died or they died
before you were 10.
It makes no difference to outcomes. You
you don't do any worse in life. You're
not any less correlated with your
father. Uh you you apparently you never
need to meet your parents for them to
have exactly the same influence on your
outcomes. So, so as I say,
this study then is based on this
observational data, right? And so it
doesn't prove anything directly.
But I'm working on a book which is going
to have all of this kind of ancillary
evidence
about the nature of social life. And as
I say, there's a surprising amount of
this says
it's not social transmission. It seems
to actually be
genetic transmission that is the
consistent pattern that would explain
people's outcomes.
When you talk about outcomes, you're
using words like social status, where
they end up in life, stuff like that.
What what what is social status based on
what you're talking about here?
Right. So, the specific measures we have
are did you go to higher education of
some kind?
Uh
what was your literacy earlier on?
Uh the best one we have is what's your
occupational status, right? And then we
also know for everyone who's most people
who are alive now, what's the value of
your house that you're living in? And
that's pretty good indicator of your
income level.
And then also what's the nature of the
neighborhood you're living in? Is it one
where there's a lot of educated people,
there's low crime rates, stuff like
that. So, we have a kind of measure of
And and that's we got down to the the
almost the street level.
Uh what's the quality of of that? And so
as I say, so we have these kind of
multiple measures. But what I've seen
with the data here is that these things
tend to move pretty closely together.
That basically high status people have
more education, more wealth,
uh higher occupational status, they live
in
nicer neighborhoods, uh they tend to
live longer,
uh all of these things. And that's why I
I think of it inherently as there's
there's just some underlying kind of
social abilities that people have.
And that that's the thing that's being
transmitted that between the
generations.
It's interesting to think about how you
tried to tease apart social transmission
and genetic transmission or genetic
inheritance, I suppose. Because a lot of
people would look and say, well,
you know, if you come from a family that
is well-off, think about the culture
that you have around the house, around
the dinner table. Think about the sorts
of things that are being spoken about.
Think about the kind of friends that
you're going to play with, the your
parents are going to have. You're going
more likely to go to after-school clubs.
You're more likely to maybe have a tutor
or maybe be encouraged to play sports or
to play a musical instrument or all of
these different things.
And yet
it seems like
behavioral genetics wins out yet again.
Yes. And so
now it turns out
I didn't I you know, because I'm coming
from an economics and kind of history
background.
And I just got interested in this and I
had this data and I thought, well, let's
try to fit a genetic model, what would
happen?
Uh in this field is very fractious and
very kind of ideal kind of ideology is
very important to people.
And
it turns out most of the people actually
don't want to believe that simple
genetic transmission plays an important
role in social life.
And so most of the people in this field
actually seem to believe that cultural
transmission of the type that you've
described is actually very significant
and very important.
But there is one kind of puzzling thing
about that, which is
people don't focus on this a lot, but
there's a lot of variation within any
family in terms of the outcomes for
children.
And children's outcomes are no more
correlated than and they have roughly
the same correlation as between a parent
and a child. What what the you know, the
correlation of child outcomes.
Now, if you really believe strongly in
cultural transmission,
I you know, when I look at I was one of
four children. If I look at the
expectations my parents had of us, if I
look at the dinner table conversations I
sat around in, if I look at the housing
we lived in, the neighborhood we were
in,
it's all the same for all four of us.
And so if you really believe cultural
transmission, you would expect that
siblings really would show very very
strong correlations. Right, because you
have you have essentially the same
environment for all siblings.
Right. But and the only thing that would
have been the only variable that you
would have had would have been some sort
of
genetic one that you got this particular
combination of sperm and egg and
somebody else got the rest.
Right. And and so it turns out then that
the one And people don't seem to focus
on that a lot that there is this puzzle
with cultural
transmission, which is how do you
explain why
siblings are actually
significantly different.
And and I would with genetic things that
is partly because you inherit different
genes from each parent.
But a lot of it is just because whatever
genetic blueprint you have, there's a
randomness about what body eventually
gets assembled from that blueprint. And
that means that even identical twins are
not identical in terms of their
phenotype, right? And you know,
people there's this very famous
investigator of twins, Plomin.
Um he had a whole project which sought
to look in detail at families where you
had identical twins and one was
different from the other. You know, like
one went to college and one didn't.
And he interviewed the twins, he
interviewed all their relatives. I think
they spent years doing this in detail
analysis.
And they came up with inclusion in the
end,
they could find nothing that would
actually explain why these differences
existed.
And so I say I think there actually it's
something again where genetic
explanation has this idea, well, there's
this this irreducible randomness
life.
And and about how the genetic
instructions get implemented.
And that explains why even identical
twins will not turn out to be identical.
Um and so
so as I say, so so cultural explanation
is this interesting alternative.
The
it it's hard to test, right? Because
someone could say, well, I believe in
culture, but I believe it has exactly
the same form of transmission as would
come through genetics.
And then, you know, it's such a loose
form of explanation,
right? Because everyone has their own
ideas about how culture operates, what
matters, is it that, you know, you have
some figure in the family that you can
look up to, is it the actual contact
that matters, is it the schooling that
people go to?
Um and so it's very hard to
um
to find, you know, stuff that would
refute a kind of cultural explanation
because inherently, unlike the genetic
explanation, it's just not super well
kind of specified. But as I say, I think
the strongest thing is this fact of the
way siblings vary within families.
And the fact that it's very hard to then
to to understand why sibling number one
is doing great, sibling number two is
struggling,
when so much is common in terms of
people's backgrounds and as siblings
when they're growing up. Why do you
think it is that this genetic
explanation of social inheritance and
social status is so ideologically
unpopular?
Um
I Well, it absolutely seems to be
because it's it's saying somehow
mechanically at birth
your life chances are pretty much
determined, right? And that uh
the state or society is not going to be
able to do very much
to actually change outcomes, right? And
so it implies a kind of relatively
conservative social policy because it
would say all the expenditures on
schools and other things like that are
really not going to have that much
effect in terms of of social outcomes.
Uh and so I think it's that. And then
also people are worried
immediately about what does that imply
about
uh the relative fertility of different
groups in society and the implications
of that, what does
you mean about relative fertility?
Oh, because once once you say, look,
what's happening is that one person is
successful in life because they have
this genetic material and another person
is unsuccessful because they don't have
the favorable genetic material,
then the issue immediately comes up,
well, you know, if this first group was
to multiply and increase their share of
society, there would be all of these
potential social benefits. If the other
group was not to do that, they would be
in avoidance of social costs. And so,
people are, I think, rightly
very concerned about the potential
social implications of this. But the
only problem is, I mean, when we're
thinking about how the world is,
it's very it's it's very important not
to to adopt certain positions just
because it would make life easier,
right? Uh I mean, when you're thinking
about, you know, the way the the the
world is actually operating,
uh it the important thing is is never to
have the end view in sight in terms of
what explanation do I favor, what
explanation do I find plausible here.
I mean, we'll just have to live, you
know, whatever this act the explanation
is is, if it turns out genetics really
is important, we'll just have to live
with those consequences.
Uh What is
Sorry.
What what is the consequence of ignoring
the genetic implication?
Um
well, I there's there's several
consequences. One is,
uh for example, I think
as a society we've come I you know, and
and I should say as a background point
here, I've made my life
working in education.
But it's firmly my belief that we've
vastly exceeded the amount of education
that people should usefully get in this
society, right? That And and we've done
that in part because it's been regarded
as the key to social mobility, social
advancement, leveling the playing field.
And now we're adding forever. Now,
instead of just getting a BA, people now
think that they have to get a master's
degree.
Uh there's there's actually,
you know, the empirical evidence that
education is actually improving people's
lives
is actually very weak.
Uh But didn't you say didn't didn't you
say previously that one of the
uh parameters that you'd used was
education level, whether or not they did
get to higher education. So, you're
saying that that as a useful indicator
of someone's future life outcomes is
becoming less and less effective at
being predictive. Uh I I I
Yes.
Uh
Here's an example of of
why this doesn't seem to be very
predictive. So, in the UK at various
states we've extended the amount of
compulsory schooling that people get.
So, I think like 1973, 46, 1919,
we've and we moved from 12 years to 14
years, 15 years, 16 years. I think now
it's supposed to be closer to 18 years.
We can actually look at those episodes
and you get then two cohorts of people.
You get the people from just before the
change who get, on average, you know,
they only have to be there till 15.
And then you suddenly get a new cohort
who on average get a half a year of
extra schooling.
And then you can look empirically and
say, well, what happened? Did that
improve these people's life outcomes?
And the answer for Britain is no.
Uh none of these adjustments to
education
showed up in any way as an improvement
in
uh
you know, income
or uh mortality,
longevity, none of these things were
actually changed. And we also have this
house value evidence. So, you could say
did the people who got an extra half
year of education end up living in a
slightly nicer house or in a nicer
neighborhood?
The answer is no.
Okay. And so, so so as I say, that I
mean, the problem is that we've
we're now spending about 10% of national
income on education in various forms.
And in part, as I say, this is really
driven by this idea that path to kind of
universal social mobility
is to get everyone educated.
And I think that's an illusion.
And that, you know, there there are
other things we could spend that income
on. One of the things we could do is
just we could just redistribute more
money
to people at the lower end of the income
spectrum.
Uh rather than thinking that everything
has to go through something like
education.
And so, you know, I'm here in Denmark
now.
Denmark is, I think, one of the most
equal societies in the world.
And it's quite impressive what they've
actually achieved in Denmark. There's
there's not a lot of homeless people.
There's um
you know, this the state will provide
for you and, you know, the the labor
market seems to provide pretty well for
people. The minimum wage is something
like 20 or 25 pounds effectively
in this society.
And so, you know, I think there's a lot
of social policy that's actually very
useful and very helpful.
And
that if we think that the things we have
to spend on are stuff like education in
order to improve social mobility, I
think that's end up just a lot of waste
of resources in this society.
Shouldn't assortative mating nudge this
stability? Isn't that kind of a little
bit of a dice roll? What what role does
marriage play in this?
Well, it it turns out in in the data
that I'm looking at, that's the that's
the key element of the story is that
we can measure assortative mating.
It turns out Britain has fantastically
good marriage records
because the the marriage record in
uh England and Wales at least, uh from
1837 onwards, it actually asks uh what
is the father of each party and what's
the father's occupation.
And what's the husband and wife's
occupation. And then also, earlier on,
it also effectively measures literacy.
And so, it actually, you know, there's a
lot of information on these marriage
records and the government is sitting on
something like 110 million of these.
And uh but it costs, I think, 11 pounds
to to order one of them.
But there's a bunch of kind of freelance
amateur anarchist genealogists who've
set about going to the record offices
and recording this data and and setting
it up on a website.
And so, we were able to get about 1.5
million of these records from this site.
And what's evident in that data is that
people are matching very very closely in
marriage.
Uh and that that's consistent and not
changing in England all the way from
1837 till now.
And that when people somehow in marriage
what mattered to people was the
underlying social status of the person
they were marrying.
And that is something that has very big
social consequences because
A,
it's going to mean that the inheritance
of status is much stronger.
And if what was happening is that men
just married a random woman, right? So,
suppose men the only thing they cared
about was the physical attractiveness of
their spouse,
and they married in that way,
then the parents would not be very
strongly correlated in status and
consequently the children will not be
very strongly correlated with any
individual parent. Because, just to
interject, a a woman's attractiveness
has a negligible or not at all
relationship between her social status.
Right.
And and and and so, so we could imagine
that kind of model of marriage. And what
that'll do then is also, over time, it
would result in less distribution of
abilities in society.
Right? Because if what's happening is
very high status people marry only very
high social abilities people,
then you get over time a widening of the
distribution of abilities in society.
And so, who decides to marry whom
actually has these huge social
consequences in terms of how strongly
status is passed on,
but also in terms of what's the overall
distribution of abilities within
society.
And so, uh
with a the marriage pattern that you're
observing in Britain then,
uh this is what is actually driving this
very slow social mobility. And you could
actually predict with genetic
transmission that
if you just force people to marry at
random,
you would actually almost double the
rates of social mobility in British
society.
Uh that's the redistribution strategy
that we should be pushing toward. None
of this education stuff. Just get people
to get people to mix the social status
that they're marrying within more.
That's right. If you just gave them a
random here's someone's ID number or
something. I guess they don't have an ID
in Britain, but here's here's your
number. Yeah. Uh and and and this is
actually very interesting. And so, so
we've actually done some work uh
on
another aspect of marriage, which it it
was widely believed that the way
marriage works is that somehow women
tend to marry up.
The women trade off
uh physical attractiveness for status in
males. And studies definitely show that
when people report their kind of ideal
marriage partner,
that women report more about income or
education stuff like that and men report
more about physical appearance, right?
And so so we were expecting potentially
in this data to find that when we have
this huge collection of marriages that
women on average would be somehow moving
upwards in this you know pattern. And
and men would be marrying women of
somewhat lower status. Now the only way
that can actually work in society if
everyone's marrying everyone
then you've got to have equality in
terms of status.
But what easily can happen is that it
could be that high status women
who are not physically attractive find
it difficult to find mates and then low
status men
whatever their characteristics are also
find it difficult to find mates.
And the interesting thing for the
English data all the way through is that
there's absolutely no sign of this.
On average
men and women are marrying people of
equal status and that's you know the end
it's the same pattern for right at the
top of the distribution
and right at the bottom of the
distribution.
And so somehow the way marriage is
operating in practice is that people are
just matching up mainly on their kind of
social status.
And that you you actually not getting
this
as I say marrying up by women or
marrying down by men.
And so so that's a kind of interesting
social aspect of our society which is
why do people choose to marry in that
way, right? It's not obvious
that that's going to be the happiest
marriage or the ideal marriage.
Why would it be that people seem to care
so much about someone's kind of
underlying status? But I think what what
this reflects is that when you're dating
someone
uh
we have these very imperfect measures as
social scientists about how many years
have you been to school, what's your
occupation, what's your income.
People getting married actually have
much much more information. You can tell
by talking to someone for not that long
a time what's their sense of humor
what's their knowledge
how smart are they, how clever are they,
how imaginative are they
and that it's interesting that these
things seem to matter a lot when people
get married
and that they're leading to this kind of
very tight assortment of people at very
similar levels of social hierarchy.
Uh and as I say they're underpinning
this tendency to have just a lot of
persistence across generations.
Yeah, so
your research
points out that historically men tended
to pair with women who have fathers with
similar social status to themselves.
That's great, yeah.
As men fall behind women in education do
you think that women will begin to pair
with men who have fathers of similar
status to themselves?
Um oh so now this yes this is clearly
happening that that women are getting
more years of education. Uh
the difference in earnings is not great
still. I think men are still ahead in
terms of earnings.
Um but yeah but I think what's just will
happen is that there's a ranking of
males as prospects in the marriage
market and there's a ranking of women.
And so now women are actually going to
typically marry men potentially who have
less level of education but I think the
relative ranking is going to remain the
same. Yeah, so maybe women will be
likely to evaluate the education of a
date's father before deciding to commit
to a date. Like does this man have the
education genes even if he himself did
not attend college? Right. So one of the
interesting aspects of the data that I
have is that
uh it turns out if you want to predict
for a given marriage how well the
children are going to do in life
there's a huge amount of information in
the relatives of the people getting
married.
And so in fact if you wanted to set up a
new dating service
you could actually tell people here's
the optimal waiting of the uncles, the
aunts, the grandparents and stuff like
that
that if you just want to maximize what
your social prospects of your children
are
this would constitute the ultimate match
then, right? So you don't genealogical
dating Yeah, that's right. And then you
could get these algorithms now
that would actually tell you you know
this would be a significantly you know
better child in terms of social outcomes
if you were to to match in this way.
Uh and so
yeah so so as I say it is interesting
because people
when they're matching they they look
like they're trying to maximize the
prospects for their children. Mhm.
Right, in terms of the choosing a mate.
Right?
Uh
and
and as I say that's an interesting
social feature. I don't know why we
would tend to do that because it's it's
not true in all societies.
So for example if you go to large parts
of the Middle East now or even
Native American communities in South
America cousin marriage is still very
common.
Where you end up actually having very
restricted choice as to who you can
marry and so that in that type marriage
you're actually less able to assort even
though you're marrying your cousin
which is kind of ironic uh that you're
that these cousins actually will be more
different socially
than the way people are actually
marrying in somewhere like England. So
they're actually
Wow, that is so insane that if if left
to random chance people will find on the
street someone who is closer to their
family social status than someone who is
actually a part of their own family.
Yes, no that's an amazing feature, yes.
But it is actually true.
That is
bonkers. That is completely bonkers.
Um so yeah so so as and and the other
thing that was amazing about this is
that this pattern as I say the
the new source of marriage data starts
in 1837.
That
pattern is there immediately in 1837
even though at that time most women
didn't formally have occupations.
And and so the way we're able to judge
how well they're matching is to look at
the parents, to look at the fathers and
see how closely are they correlating in
terms of this marriage pattern.
And and so as I say this is a time when
most of these women that men were
marrying were going to be engaged mainly
in raising children.
But still when they married they wanted
someone of kind of very similar social
position
to themselves.
Um
and and so as I say so so it's it is a
surprising feature of the nature of
marriage in this society.
Does this mean By the way one thing I
should add is
part of the reason I've taken up this
position in Denmark
is actually to get access. Denmark has
this amazing set of kind of register
data
where everyone here has an ID number and
every action in your life is recorded
under that ID number.
And the government then so this is true
of Norway, Sweden, Finland, Denmark.
Uh
social scientists come to these
societies because you know they to take
just one example I've seen a paper
which looks at people's earnings
and it's correlation and connection with
the psychiatric medications that they
were prescribed.
This is the real surveillance state. Who
knew that Scandinavia was the real
surveillance state? Dear God. No, they
don't reveal any individual information
but as I say that they they have this
amazing set of data here
and so one of the things we wanted to
look at is well is this pattern you see
in England is that just peculiar to
England or
Yeah, I mean that was my first my first
question. England
very classist system
very well established we use words like
posh you know it is still very ingrained
accent denotes status an awful lot
school that you went to grammar schools
the introduction of things like that old
boys clubs gated communities all that
sort of stuff
very prevalent in England.
What's the likelihood that this is a
quirk exclusive to just the United
Kingdom?
Right. And
yes and so the reason I actually was
interested here was to see could we look
at say modern Denmark because everyone
thinks of this as a very high mobility
society. It's very egalitarian
and very different. Now uh there's a
study that's been done in Sweden
where they've managed to assemble a kind
of a similar kind of panel of relatives
but actually in this case they're just
looking also across people who married.
So they're looking at who's what's the
connection between you and your
brother-in-law
you and your brother-in-law's wife's
cousin
where they assemble 141 different types
of relatives and some of them go across
five marriages, right? And with this
data they have they can actually link
you to people who you never actually
going to meet in social life but you
know you're five marriages apart. And
what is interesting is
people maintain a correlation in
outcomes like education even across five
marriages, right? That's how strong
these social links are.
And when we look at then how strong that
correlation is in marriage in Sweden,
it's the same strength as in England.
People are matching up in the same way
in marriage in terms of their underlying
status,
and they have this very slow implied
rate of social mobility also in a place
like Sweden.
And so I think this is this is a general
kind of maybe North European or
European, probably all of Europe, kind
of pattern, right? And I don't know what
it's going to be like in in some other
societies. I suspect it's not going to
be that different, right? When I read
about places like China and the kind of
things that people are looking for in
terms of mates in China.
And so I think, you know, the British
have, you know, and and I've, you know,
I as I say, I grew up in Scotland and
then spent I was an undergraduate in
England and then I've spent a lot of
time in America.
The British actually keeps beating
themselves up that somehow they have a
uniquely class-ridden
and classist society,
but there's actually no evidence of
that, right? I mean, social mobility
like to abuse ourselves. You know what I
mean? We will find something to feel
ashamed about. Just that Puritan that
Puritan work ethic is I'm whipping
myself with a cat of nine tails. That's
what we're here for.
You know, and and it turns out so I I
grew up in Glasgow in a fairly kind of
gritty area,
and so I had a good friend there
who
uh
became an oil trader in London. He was
being very successful. You know, and he
went to university before he did that.
He actually has married a woman who is
from
a very distinguished family in the
English upper classes.
Uh
and, you know, and and Clambering out of
the muck and the mire one rung at a
time. Congratulations, mate.
So So as I say, so I've even seen in
kind of personal life that there is kind
of you know,
quite a lot of social mobility. My and
and also from studying England in the
past,
um there's this group, the Huguenots,
who arrived in England in the 1680s, and
they were Protestant refugees from
France.
And relatively educated, but they, you
know, they had their own religion, uh
they had spoke French.
Um they It's amazing how quickly they
assimilated into the upper reaches of
English society.
And people with these Huguenot surnames,
which are quite distinctive,
by 1800, they were
30 times more likely to go to Oxford or
Cambridge than the average person in
England, right? And so, you know, so you
think about these places as, you know,
exclusive old boys clubs, stuff like
that.
But the experience of English society is
that there there definitely is this
upper class, there are these fancy
schools, there's Eton, there's Harrow,
there's all the rest of that stuff.
But my experience looking at this is
that it's a very open upper class. If
you've got the money, the education, the
connections, the doors actually
the doors actually open. Okay.
Okay, so does this mean largely that
people who are in the upper class are
locked in in across time? You mentioned
that one of your friends has managed to
clamber out of the blood and the feces
and the hay and get
get up in get up into the highfalutin
upper troposphere.
Over time, do these people
like revert back to the mean, revert
back to their mean?
Um well, I mean, the the important thing
about the as I say, the upper class is
that that there's, you know, it's slow.
It takes about 300 years, but that
there's a universal force of kind of
regression into the mean.
So if we go back and take people 300
years ago who are the most elite people
in society, I mean, it's taken a long
time for it to happen, but
there is this universal tendency to move
downwards if you're an elite, and if
you're at the bottom, there's an equal
tendency to move up.
And that's one of the astonishing
features of social life looking at this
genealogy is the people in the bottom
10%.
They're the ones whose kids have the
most prospect of upward mobility.
And you know, it's very hard to actually
then
kind of stop people falling into poverty
because it's not that you can go and
find the bottom 10% of people and say,
"Okay, they're the ones we need to
treat." Because it turns out a lot of
people who are falling into poverty are
people who are coming from a bit higher
in the social spectrum who just have bad
luck.
And kind of move down.
Wow. Right? And so so that you know, one
thing that's actually interesting to me
is so I've spent a lot of time studying
economics, and frankly,
we've accomplished almost nothing. I
don't know why there's a Nobel Prize in
the economics because, you know, we
can't predict what the outcome of the
economy is going to be next year, we
can't predict which are going to be
growing economies, which are declining.
Macroeconomics is just a random
effect.
But when it comes to social mobility,
there at the group level, societies
actually are you see really almost a
kind of physics of social mobility.
Yeah. So if I tell you, you know, here's
a here's a thousand people who have the
top 1% of social status,
I can predict pretty much exactly where
their children will be for the next 10
generations.
Uh That's in So just think about that
sentence that you've just said there.
That's like clairvoyance or
divination or something. Right. No, I
mean, what it is just saying that at
least at the you can't predict for any
individual, right? And for every
individual family, there's different
path, there's a lot of randomness,
right? So that's the thing that we say
to people is, "Look, the the the good
news is
your outcomes don't seem to be entirely
determined by genetics. There's also
complete randomness as well."
Fantastic. Fantastic. Where's the
Where's the agency in this? Oh, don't
worry about that. Don't worry about
that. There's some dice being rolled
somewhere by a god.
Yeah, but I mean, this is this is a a
Plowman's Maxim, right? Genetics to do
not predetermine, but they do
predispose. Yeah. And when you smear
that across enough of a populace, you
end up with just like you like
thermodynamics, right? It's like winds
that blow in particular directions, and
they encourage particular outcomes.
Right. No, I mean, what So what is
impressive actually I mean, so this is
why I'm actually I'm
almost a little surprised
by how
how kind of exercised people are about
class and social mobility, right?
Because
somehow there is this kind of feeling
that that that there is this permanent
advantage group that they're able to
take advantage of their position all the
time, and, you know, get all of these
unearned benefits.
Um if you look at people who are at the
top 1% of the society, what is more
impressive is whatever wealth they have,
they're not able to stop their children
moving downwards on average. Because of
regression to the mean. Yeah. And
they're not There's nothing they can do
that
Well, I hear I mean, I I can I can bro
bro science an explanation for why that
is, which is that most people aren't
able to look longitudinally at anything.
They're able to look at things during
their period of life, and when they came
in,
these people were at the top, and when
they go out, those people are at the
top. You know, maybe there's some
movement, but this regression to the
mean happens over long, long, long
periods of time. It's this generation,
this genera this idiot child that
decides to gamble his money away, this
you know, drunk, this blah blah blah
blah blah. Slowly just chips and chips
and chips away, but anybody that's using
this sees a them and an us. It's a
tribal game, and they've been at the
top, and they will always be at the top,
and this is exactly why
the Rockefellers or the lizard alien
people or whoever it is that's in charge
of the world have always been there and
will always be there.
Yeah, no, I I agree. I mean,
the
uh
yes, it's
as I say, it's hard for people to take
that kind of long perspective. And and
even, you know, modern uh economists or
sociologists often are just looking at
the current generation, the earlier
generation. So one kind of nice
thing about the field I'm in, which is
looking at, you know, people 300 or 400
years,
is that you really can see that dynamics
play itself out, and you can and and the
other thing that you can see is that all
of these incredible social changes with
political franchise, education, social
services, all the rest of that stuff,
hasn't fundamentally changed British
society.
That we we could be living in the
Victorian era. It's the same era. Yeah,
I mean,
the obvious the obvious question is,
what's the implication of this
for
a a society that prays at the altar of
meritocracy?
Like what what what are the
implications? You put all of this data
together, you've realized this sort of a
thing.
What does this mean? Like what what what
what are the implications? Well, one
implication is that I is I think that
society is more meritocratic than people
tend to believe.
That people with ability
tend to be able to move up within the
society, right? And and people without
ability are tending to move down no
matter what their parentage was or what
advantages they got from their
parentage. And that that people tend to
be
over-focused on this kind of absence of
meritocracy or the importance of your
cab lineage, your class, and stuff like
that. And so one thing I actually draw
is some kind of sense of we do live in a
surprisingly meritocratic world.
Now, in other terms, in terms of social
policy,
um
one
implication, one immediate implication,
for example, is if you look at the
experience of the Huguenots coming to
England,
their descendants
are still five times as likely to go to
Oxford and Cambridge than the average
person in England 300 years later.
So one kind of interesting implication
of this is
that if you're concerned about the
output of the society as a whole or the
social functioning of the society as a
whole,
then in immigration policy,
you should really look seek out
high-status immigrants, right? Uh
because they
not Would that Would that not push down
the social mobility of the native
population? It would.
But But it would you know,
that group will eventually be
assimilated into the society as a whole.
And so if we look, you know, five
generations from now, the society as a
whole will be better off.
a more productive populace.
Right.
But it is true, you know, if you have
elite immigrants, then they tend to
displace the upper classes.
Whereas if you have low-status
immigrants, they that tends to favor the
upper classes in the society, and it
tends to compete with people at the
lower end of the society. But it does
say that
you know, immigrants are actually going
to have a surprising kind of long-term
impact on the society. They're not just
going to be absorbed and leave the
society otherwise unchanged.
Right, because you've taken a a kind of
a hermetically sealed genetic bomb
and you've deposited it, and the
aftershock, the aftereffect of that is
going to continue down the road.
Right.
And and and now it it turns out, so one
of my co-authors, Neil Cummins, has done
some study, you know, because I'm of
Irish origins.
he's years of age. He was born in
Ireland.
Uh
Irish immigrants to Britain are still
somewhat of an underclass in Britain,
uh even though a lot of them have been
in Britain for 100 or 150 or more years.
Doesn't bode well for the Irish
genetics.
So So yes, as I say, so if it ends up if
that is really because of the uh
the genetics of that population, it's
kind of interesting that it's it
actually
it has an impact for for very long uh
time.
Uh
and so So because there are some views
that would say, "Look, everyone has
exactly the same potential."
You know, so when immigrants come in, it
doesn't matter what their educational
background is, what other things are,
because Throw them in the primary school
and a secondary school and get them a
sixth-form degree, and they're going to
be just the same.
And it's it's it'll make no long-run
impact on the society.
Uh but as I say, I think if you really
do believe that there is this element,
then it would say, "Well, in immigration
policy" So So some societies, for
example, like Australia, New Zealand, or
Canada,
have these incredibly restrictive
immigration policies where basically
they want you only if you're pretty
highly educated.
Uh and what that would say is that will
actually have kind of long-lasting
impacts on those societies in terms of
average educational levels, average
ability levels, uh
and uh So that's So but other than that,
you know, look, people choose to have
children, they choose not to have
children.
They will have these social
consequences. It would have these social
consequences if it's transmitted also
just by social means.
Yeah, that's that's an interesting
that's an interesting question, given
that we've got uh
uh declining birthrates at the moment,
uh for the first time in quite a while,
and the particular cohorts that are
choosing to reproduce are uh assorting
as well. Uh it seems like people who are
more right-leaning are having
proportionally
less fewer children than people who are
left left-leaning. Uh downstream from
that that has to select in some ways for
social status, educational achievement,
so on and so unless it's totally random,
which it could be, but it seems unlikely
that that would be the case. Uh have you
got a prediction
given the changing birthrate of what
this is going to do to the inheritance
of social status?
Well, uh it turns out there have been
some studies in England because they've
got this thing, the UK Biobank. And so
the UK Biobank has metrics of what your
educational potential is based on your
genetics.
And
Base Britain, dear God. Uh
but uh then you can they can actually
people can look at it and say, "Well,
how many children do people have based
on what their educational genetic
educational potential is?" And the
answer is it's very slightly uh what's
called dysgenic.
That is, there's a very slight tendency
for people with lower potential, just
genetic potential, to to have more
children. But But it's really not that
significant. But what is actually
interesting, again looking at this data
in the past in England, is that these
forces of relative fertility across
different groups were really big in the
past. And so in the period leading up to
the Industrial Revolution, the upper
classes in Britain were super fecund
and were basically having 50% more
children than the lower classes in each
generation. And so you do see this
period where if you think if it is the
the case that it's all based on genetic
potential, that the average abilities of
England were rising.
Immediately after the Industrial
Revolution, we moved to a completely
different phase where the upper classes
just gave up having children.
And within like one generation, they
moved from having three or four on
average children to having one child.
It's amazingly quick transformation.
And so then actually you enter this
other period where you are And this is
the period where the eugenicists are all
running around cuz they were responding
to what they saw as this incredible
social problem.
But then since I think the 1960s or
something like that, there hasn't been
that much change. But there are actually
these periods in the past where you
would actually get these significant
changes
in what average ability levels would be
in Britain.
Has there been any other unique step
change
uh in the last
recent history uh that means that some
of the rules and lessons that we've
taken from 1600 to 2000 or whatever uh
may no longer apply? The introduction of
uh hormonal birth control and reliable
contraception, uh the introduction of
homeschooling or of the internet, or you
know, like is there anything that you
think is a potential step change, a
difference of kind, not just a
difference of degree, when it comes to
the influences on this stuff?
Um
uh to be honest with you, no. I mean,
I actually think that uh
people look at all the new technologies
we have and everything else, and they
think, "Oh, fundamentally, you know,
social life must have dramatically
changed, and the possibilities have
dramatically changed."
But uh
you know, the other than the decline in
the number of children,
we're really not seeing a lot of change
in the nature of social life in Britain.
It It hasn't changed that much since,
you know, the the pre-industrial era.
Uh
and
uh you know, there's a surprising kind
of constancy to the way people live
family life, the way people produce
children, and stuff like that, other
than the fact they just have many fewer
of them.
Um and so So yeah, I'm not expecting any
great social revolutions from things
like, you know, so things like assisted
reproduction technology, that's become
important. It kind of favors upper-class
people because it's expensive. And you
know, so it it's going to affect
potentially relative fertility. But I
think it's still the case that it's a
kind of minority of all children are
born in that way. And so I don't see it
as having dramatic impacts. Now, the one
thing
that is on the horizon
that would be kind of Personally, I
would find a little bit worrying.
Are you going to talk about embryo
selection? Yes.
There it is. IVF, embryo selection, I
knew it.
So uh I have talked to some of the
people who are who are have got venture
capital now and are trying to develop
these technologies. Now, the thing about
embryo selection is
currently you've got to look among among
your own embryos, right? And so there
isn't that much
It's not modification, it's selection.
Yeah. Yeah, there's not that much range.
But I would be convinced that in
somewhere like China
they will go ahead with this, right? And
and when one illustration of this is,
now when the United States is, you know,
it's quite common for upper class
parents to think, well, a a kind of a
nice pathway to a good college is if
their kids are good at athletics.
And so there are all there used to be
all these slots where you could be in
the hockey team, you know, at Harvard.
Uh a whole bunch of those middle class
parents were giving growth hormones
to their perfectly normal sized children
in order to gain them. Create some studs
that would go get into an Ivy League
education. Yeah. And and, you know, and
costing a huge amount of money. I mean,
this stuff is incredibly expensive. And,
you know, if parents are willing to do
that,
right? If they're willing to take, you
know, someone who's 5 ft 10 and say,
we're going to take you to this special
doctor and get you these growth
hormones,
um then people will engage in embryo
selection.
So, I don't I don't disagree. I I do
think that it plays into at least the
the use of growth hormone plays into the
highly environmental, highly uh
um culturally influenced, non behavioral
genetic, non genetic determinism
view of the world. I think that the
upper classes
are going to have to square the circle
of accepting behavioral genetics as as
powerful of a force that it is because
publicly the luxury belief that is often
put forward is, you know, it it it it we
just need to do more welfare and we need
to do so on and so forth and it doesn't
really matter, you know, you haven't got
this determinism through genetics and
stuff. That's perilously close to
eugenics. That just sounds an awful lot
like something that Adolf Hitler would
have spoken about. Meanwhile, they're
mating assortatively. Uh but they they
are going to have to ultimately put
their money where their mouth is with
regards to this because if
certain families that decide to use
embryo selection and then maybe even
gene enhancement embryo enhancement
techniques, uh
they're going to fall behind. It's an
arms race ultimately for offspring and
those people are going to fall behind.
Yeah, and I mean, the the at least the
evidence in the US is if you look at how
much people are willing to spend for
private schooling, which it it's unclear
how much advantage that has, but they're
spending 50 or 60,000 a year on stuff
like that. that. And so I'm I'm
confident in place like the US they
would do this, but I'm even more
confident in a place like China that
they would do this. I mean, because
there people are are trying to have boys
as opposed to girls or stuff like that
and they're willing to abort a fetus if
it's the wrong gender.
Uh and and so I actually I I do fear
that, you know, and and there are
definitely people who want to break down
that barrier and push, you know, us
towards these technologies. The only
thing is, I mean, things like
educational outcome depend on like a
thousand different loci on the genome.
And so it's not going to be easy to
There's the education gene that we just
need to tinker with. Yeah, right. You
know, so there's no simple uh solution
uh to that. Uh
but but it, you know, it it seems for
sure that that stuff like that will will
come it in future. And um and then, I
mean, the the other puzzle will be will
people just decide, well, maybe I I
don't need my partner's egg.
I'll get some other egg. I like I like
you as a wife around the house, but your
genetics Yeah.
But
There's this really smart girl at work.
So, uh
so so so there, you know, it it it will
be interesting to see uh
what people do. But I think I mean, the
advice for upper class parents now is,
you should just enjoy your children,
right? If you really are upper class,
they're unlikely to exceed you in terms
of their outcomes in life. They're more
likely to move towards the mean. And so
if you're having children, it should be
with that realization that, you know,
that's just the nature of social life. I
I can't resist when I'm teaching
students, I should never do this. I'm
sure they hate me. I actually point out
to them
that since they actually represent an
upper class group,
if there's 50 of them here in the class,
it's predictable that their children
will do less well in life than they
will.
All of this hard work to give your
children the advantage so that they can
slip down this snake and just end up a
little bit behind where you were. Yeah.
So, I should I've got a future at that
resolution to self, do not find this
out. Did you see this study on physical
attractiveness and intergenerational
social mobility that came out recently?
Oh, I don't think I did. So, uh Alexey
Gugushvili
and
Gregor's Bulczak. I've absolutely
butchered that. Physical attractiveness
matters both for males and females
intergenerational social mobility
outcomes, but it is more important for
males even when childhood
characteristics are accounted for. Using
data of about 11,000 individuals from
the United States National Longitudinal
Study of Adolescent Health, we
contributed to the existing scholarship
by investigating if physical
attractiveness assessed when individuals
are around 15 years old is an important
predictor of intergenerational social
mobility measured after 20 years.
Results, we found that physical
attractiveness matters for both male and
female intergenerational social mobility
outcomes, but it is more important for
males even when childhood
characteristics, such as various aspects
of parental socioeconomic position,
individuals health, a proxy for IQ,
neighborhood conditions, and
interviewers fixed effects
accounted for using imputed data for
observations with missing information.
Across three measures of social
mobility, education, occupation, and
income, physically attractive males are
more likely to be socially mobile than
males of average attractiveness.
Conclusion, physical attractiveness is
an independent predictor of
intergenerational social mobility
outcomes regarding individuals
educational, occupational, and income
attainment.
So so
couple I I I actually I haven't seen
that paper. I I do need to actually go
and look at it now.
Uh but um one thing that's interesting
there again is you you would expect from
the conventional wisdom that it would be
women
who would actually be the ones where
physical attraction would match up more
than men. But what I can tell you is
that someone has just produced a working
paper on economists
where they've actually identified their
physical attractiveness and found that
more attractive economists have do
better in terms of publication.
And and I don't know what they must have
gone to the websites of universities or
something like that and then scraped
these things and then had someone rate
them.
Uh and there, as I say, the puzzle is
journal editors not normally look at
pictures of people, you know, when the
paper comes in
and say,
well, how handsome or how tall is this
person? Uh and so I suspect for these
things that probably
um
physical attractiveness is just another
part of social competence.
That basically highly competent people
know to
get a nice haircut, you know, and
occasionally shave and stuff like that.
And that uh that that it's really just
an another kind of imperfect indicator
of basically what people's kind of
overall social abilities are.
What was the response when you dropped
this paper?
Oh, this uh the the PNAS paper. Well,
well, you'd probably have heard about
that. I I got uh canceled at Glasgow
University.
Tell that give us give us that story.
But but that was in some sense that was
my fault because I had published two
books each with a Hemingway pun.
So, my first book was a farewell to
arms, a brief economic history of the
world. The second book was The Sun Also
Rises, Surnames and Social Mobility.
And so there's a great pun that involves
uh
genetic transmission. And so that is For
Whom the Bell Curve Tolls.
Uh IQ and social life not IQ, sorry,
genetics and social life.
And so anyway, I was due to give a talk
at
uh the
uh economics department at uh Glasgow
and this was in the time of COVID. And
so I call in and they say, well, just
one problem. The the dean had ordered
that the cancel the the seminar be
canceled.
There was a petition by a hundred
members of the faculty
uh saying that they this was
pseudoscience
uh
that eugenics was to be opposed in all
of its forms.
And so it was astonishing because then
the dean said, well, I actually have
looked at the paper and I don't see any
problem with the paper, but the title is
a problem. So, if you would just change
the title, we'll reschedule the seminar.
But then I felt on principle that I
can't really have the I don't care that
much about the title, but I can't have
the dean uh tell me that.
And so that, as I say, it was an
astonishing turn in universities
that a bunch of people, and I'm sure
most of those people are in, you know,
humanities or sociology or other
subjects like that,
feel that they can actually call for
cancellation of of something else. I
mean, so that you you could imagine they
could come and be critical and stuff
like that. But but also, I mean, that
that we reached that stage. And and
effectively,
when they did that, there there was no
cost to the university of doing that,
right? I thought the the the dean and
the principal of the university played
it very well because as administrators
because they said, "We are not canceling
anything. There's just so much interest
in this talk that we think we need some
kind of enhanced security."
And so, we we're just deferring things
to to get to a better place.
Um but the funniest thing then was that
someone put me in touch with a reporter
from The Times.
And I thought, "Well, you know, they
should publicize that these guys do
stuff like this."
And The Times now is the world's most
worthless newspaper. The reporter for
The Times had a story that was
headlined, "Eugenesis denied opportunity
to speak at Glasgow University."
sake.
So so as I say, it's it is
And and they couldn't even get my age
right or, you know, there were various
other things they couldn't get right in
the story. And so so yes, so that has
actually been uh
a a concern.
Uh and and I also noticed I mean, so
when I'm doing this stuff, you know,
it's there's every possibility that
something is wrong, that you haven't
done things correctly, you know. That's
the nature of doing these kind of
studies.
Uh but I do notice that the the kind of
Twitter climate that surrounds anything
that has any hint about genetics
is brutal and unforgiving, right? And
people are just ready to go to the
barricades.
Why do you think that is?
Uh I I honestly I
don't really understand why it's become
kind of so ingrained because for
example,
height is genetically determined,
right? And no one seems to get very
upset about that fact.
Uh and they do all of these studies, the
same kind of studies they do for
education. They can tell you for
everyone, here's what their height
potential is.
Uh we know how it's transmitted, we know
it's equally transmitted from mothers
and fathers. And and you know, and and
so people or eye color or other stuff
like that, people seem to find that's
perfectly fine.
So why
people somehow think that because social
characteristics are also genetic
potentially genetically transmitted
that it's time to kind of to go to the
barricades and to just,
you know, think of some reason why this
cannot be true?
you know, use your theory of mind, what
do you think this is a threat to to
them? It's evidently a threat to
something. Yeah, that it's an
interesting question. I mean, why?
Because it's not just that people say,
"Oh, I'm not interested in that." Or,
you know, "Don't tell me that." And
stuff like that. They actively want to
exclude any such discussions from the
academy, right? I mean, they they want
to close down those types of
investigations.
Uh and
uh
you know, and and and as I say, I I I'm
still a little bit mystified as to
uh why,
you know,
why the
in particular this has become so
controversial, right? Cuz I I say I've
noticed now I've read a bunch of stuff
in behavioral genetics. And a lot of
people who are practicing behavioral
genetics are very busy
trying to find reasons for why
behavioral genetics does not directly
affect that much about people's lives,
right? So where, you know, so now
there's this thing called genetic
nurture. I I don't know if you've read
about that.
No, what's this?
So
Sounds awful. It sounds It sounds like
it's going to annoy me and I'm going to
think about it for the rest of the day.
Right. So here's this interesting study
that was done just a couple years ago.
Uh you inherit half of your parents' DNA
on average.
And so,
what they did was they can type that DNA
and say, "This is what your educational
potential is." And so what they did in
this study in Iceland was they took
people's outcomes. They had their own
DNA and then they had the DNA that
didn't inherit from their parents.
They had no influence on their body,
right? Because this was the stuff that
didn't get transmitted to them. And then
they looked at predicting how many years
of education they would get as a
function of the DNA you did inherit and
the DNA you didn't inherit.
And it turns out the DNA you didn't
inherit is also predictive of what your
outcome is going to be.
And it has about half the weight of the
DNA you actually inherited.
And what they explanation then that they
proposed for this is that basically,
maybe the way genetics is working is
that your parents, because of the kind
of DNA they have, set up a certain kind
of an environment and a certain kind of
nurture for you.
And that's actually what's doing the
work. That's what's transmitting to the
next generation what your social status
is. And then it's going to be correlated
with your DNA because you inherited the
DNA from the parents. But it's not
directly the DNA that's doing the work.
It's the environment that's actually
There's so much acrobatics and
going on
to
try and dance around
Oh my god. Wow, that's that's really
impressive. I've got I've got a circus
I've actually got the image of a circus
in my mind at the moment of someone
doing like spirals through the air.
Yeah, I don't know. I so I I've had a
couple of conversations. I had a
conversation with Paige Harden a few
years ago that wrote The Genetic
Lottery. Uh Paige, very very great
researcher. Uh Stuart Ritchie's been on
the show. Plomin's been on the show. Uh
Stuart's Stuart's fantastic. Paige I
found particularly interesting uh
because, you know, she's somebody who is
politically from the left but uh
scientifically um
from the behavioral genetics camp. I A
couple of things that I can think of.
Uh anything that looks like
g- gene-ish,
like genetic type explanations, uh
immediately lambasted as being right of
center or far right or, you know,
completely like bigoted. Um
the academy at the moment is
left-leaning uh and becoming
increasingly uh feminized as well. Like
just literally in the um uh proportions
of women that you have that are
attending as undergraduates. And, you
know, this is going to grow into mostly
female professors over the next few
decades as well. Um
some great research by Corey Clark found
that behavioral genetics and
evolutionary psychology explanations
were most likely to be disliked by
female professors um because they are
seen as being uh less empathetic.
They're sort of less touchy-feely,
they're less egalitarian. Uh whereas the
male professors uh were more uh happy to
have this come across. So I think
generally you have this shift toward a
people not things or a empathy not
reality um approach. Uh that that could
sway things in in one way. And I guess
in another,
you know, I come from a a very
working-class background. The The only
thing that was remarkable about
Stockton-on-Tees was that it had the
highest teen pregnancy rating in the UK.
And then after a while it it didn't it
didn't even have that anymore. Um it had
the widest
high street in the UK as well, I think.
The widest pedestrian high street in the
UK. So really clutching at straws to try
and come up with something. Um and, you
know, I I feel very proud. I think I I
think I'm the first person in my family
to go to university. I ended up getting
a master's as well. And I I I really
love the things that I do. And I see
in myself I do feel sometimes like
being told that my successes
uh aren't mine to own quite so much
feels it feels disempowering in in a
way.
Um it also feels reassuring in a way
because you can kind of go hands-off the
wheel in some regards. Right. And but it
does make you think, "Well, uh
hell. Like I I I thought I worked really
hard at that thing." And I did, right? I
did. I had to do the thing. And the
thing was hard. But for someone to come
along and say, "Well, yeah, but you
didn't choose your conscientiousness
level. And you didn't choose your
openness to experience. And you didn't
choose your your eroticism. And you
didn't choose your blah blah blah."
And you're like, "Yeah, I get that."
Uh and it's a difficult circle to
square. And I'm I'm I'm still yet to
work out how to fully fold this into my
worldview, you know? I'm I'm currently
in London uh about to do my live tour.
And I've got these live shows that I'm
doing. And I'm standing on stage. And
I'm telling people on stage that they
have way more control over their
outcomes than they think because the bar
is set incredibly low because most
people have externalized their locus of
control. And if you take a tiny little
bit of work ethic and apply it, that you
can make massive changes in your life
because I've seen this myself. But for
me to square that circle with this
genetic predisposition thing is really
really difficult because I know that
there are things that people can do that
can give them better outcomes even later
into life because it happened to me.
Right. And yet,
over time, genetics is this, you know,
this sort of gravitational force that
just sucks people toward whatever they
were supposed to be in any case. Uh IQ
I I agree with you that I mean, it is
you you know, because the way we lead
our life is by making all these
conscious struggles and making these
decisions and and deciding to spend time
on this as opposed to something else.
And so it is very hard to square with
saying, "Well, that's just that was just
your the lottery produced. That's the
type person you are."
And
yeah, no, I and I agree for motivational
speakers that the news about genetic
transmission is not great.
Right, guys. I know that you were coming
here to feel empowered, but we're going
to do an hour and a half on behavioral
genetics. Leave feeling despondent.
Goodnight.
Yeah, wow. I don't know. I don't know.
Everything interesting that happened in
your life happened about 30 years ago.
Yeah. Yeah. Yeah. Well, I mean,
you know, this was this was Plomin's
Plomin's big piece of advice. Like the
single most important decision that you
can make in your child's outcomes are
who you have them with. And if you want
to have if you want to have a better
child, you know, don't bother reading
books about diet and neonatal care and
and optimal
bedroom temperature for
neurological growth during the toddler
years and all the rest of it,
just spend more time finding a smart
partner. Right? Like that's that's the
that's the big solution. And it's
disempowering and I think that it pushes
against the a meritocratic world that
says, "Your successes are yours to
bear."
Alond Botton's got this beautiful
beautiful analogy. I wish that he had a
conversation with Plomin or or yourself
or someone cuz I think it would have
been really great. He says um
back in ancient Greece, the beggars on
the street were referred to as
unfortunates that Lady Fortuna hadn't
blessed them, right? And you'll remember
Lady Fortuna, she's holding a set of
scales. And the reason that she's
holding a set of scales is that she
gives and she takes away, right? That
there is supposed to be this balanced to
the universe, which I think is a nice
excuse for why some people have good
things and other people don't. That oh,
they'll get their comeuppance
eventually. But if you roll the clock
forward by 2,000 years, what is it that
we call them? People who don't have
anything going on, they're a loser.
Right? It's not that they're
unfortunate. It's that if the people who
succeed are worthy of bearing the fruits
of their successes,
the people who don't succeed are worthy
of bearing the losses of theirs as well.
And that's why this language that kind
of centers the locus of control upon the
individual has has changed. And that is,
you know, fundamentally what a
meritocracy is.
Uh
you are able to enact change in your
life.
Your merit is what will determine your
outcomes. And there are relatively few
barriers in the way. And it means that
for the people maybe this is a luxury
belief as well in some regards. People
that are at the top, they don't want to
be told that the only reason that they
managed to get into this highfalutin
institution was because of their
mother's mother's mother's father's
mother's
all the way back.
Yeah, so I mean, maybe you could say,
"Well, there is this always this random
element." And maybe it's openness to
kind of experience or something like
that can can increase that randomness,
right?
That that this would be the thing to
say, "Look, like half of your outcomes
in some sense depend on just random
shocks." And so maybe there's a way of
kind of choosing to take more gambles in
life,
right? And
and
uh Right, because for example, as an
academic,
there's certain types of paper you can
write that are just much more risky than
others, where, you know, half the time
it's going to come to nothing, you know,
more than half the time, 90% of the
time, but it might kind of pay off. It
might, you know, go somewhere.
Roll the dice. Yeah, so so that and that
would be a thing about what kind of
attitude you have to life, right? Are
you going to be conservative or kind of
afraid of of these things or
you know But I suppose, you know, coming
into it, well, what have you got? Are
you trying to conserve or are you trying
to explore? Are you trying to hold on to
what it is that you have? You know, if
you've managed to come from a family
that's from a wealthy background, maybe
you do. You
like let's just don't be the generation
that it up for, you know,
great-grandpa who made a few million
pounds doing whatever whatever. Like
let's just not be optimized to not be an
idiot as opposed to be a hero.
Whereas someone that's lower down the
distribution, you would look to explore
more than exploit, right? We need to
I've got very little to lose. My
downside is limited. My upside is is
basically asymmetric. So
yeah, fascinating fascinating. Greg, I I
think it's so interesting. I'm really
excited for you to write this book. I
think it's uh
I think it's I I don't know what the
conclusion is. I think that what will be
really important when you do finally
sort of round all of this out will be to
try and
put some sort of like I don't know. How
does someone ameliorate this into their
life? I think is what you know, it's
fascinating all the way down. Super
interesting. Really really really cool.
The question that everyone's going to be
left with is
All right. And now how am I supposed to
see the world and myself? Right. It's
very difficult. The the one very
practical piece of advice I would say is
that as a modern society, we are
obsessed with child-rearing and with and
effort in children.
And and we have a society where
increasingly it's not clear that we're
actually going to sustain ourselves as a
society, right? And so one kind of
interesting message I think would be to
say,
"Look, there's not a lot of evidence
that all of that stuff matters much.
Just have children and enjoy them,
right? You don't have to go through this
excruciating kind of thing called
parenting.
You could just relax, have a glass of
wine.
They'll be fine.
Not while you're pregnant. Not while
you're pregnant.
after that, right? Yeah.
But but you know, and and that actually
would be one kind of I think an
an important lesson that actually people
would would need cuz I know as a first
parent myself,
we went to ridiculous extents in terms
of what we did, you know, as parents.
To try and determine and predispose your
child's outcomes despite the fact that
they're on a set of train tracks that
are heading to the same destination.
Yeah. Yeah. And and
you know, if I could get all that time
back, that's what I want.
But anyway, so so there are some kind of
upsides to this.
Uh and um
And then you know, but
as a person kind of intellectually, it
it's kind of nice to see that there
really even in the complicated social
world that we live in, this idea that
there really is almost a kind of physics
to social life. Mhm. It's kind of
attractive and and
kind of powerful.
Uh
So
yeah, so I guess my big ambition though
in life is not to not to write a how-to
book for
for middle-class parents. Ameliorating
behavioral genetics. No, I understand.
Great clock, ladies and gentlemen. Greg,
I think your work's fantastic. This is
really really interesting. I can't wait
to see what you do next. Where should
people go if they want to keep up to
date with your work or read more of the
stuff that you've done? So so the
article that just came out in
Proceedings of the National Academy of
Sciences is actually open access. And
it's actually not that hard for people
to look at that and read that.
And then, you know, I have if you just
Google my name, I have a website with a
bunch of kind of working papers on
various topics that they they can do.
And then hopefully in a year or so there
will actually be a book finally.
Thanks a lot.
My pleasure. Thank you, Gregory. If you
