Video summary

The podcast begins with an exploration of common misconceptions taught in schools, utilizing a website called Retro Codex to identify facts that have since been disproven for those who graduated high school around 2000 or later. The discussion highlights several specific examples, such as the belief that lightning never strikes the same place twice, when it actually hits locations like the Empire State Building multiple times annually; the idea that bulls charge at red colors rather than movement and physical provocation; and the myth that goldfish possess only a three-second memory, whereas they can retain memories for years. Other debunked myths include George Washington having wooden teeth—when he wore dentures made of tin, gold, and lead—and the notion that hot water is more effective at killing bacteria during hand washing compared to cold water. The conversation then shifts from these scientific corrections to a broader philosophical debate regarding how educational institutions present historical narratives to children. One speaker argues that schools traditionally teach simplified or "wrong" stories first—such as idealized versions of Thanksgiving or Columbus's discovery—to allow basic concepts to sink in before introducing nuance and complexity later. They suggest this approach helps build patriotism by letting students appreciate a country's great deeds before learning about its flaws, similar to how one might tell a child their father is good before revealing his past mistakes once they are adults. However, the counter-argument presented suggests that modern education often front-loads grim realities, such as teaching fourth graders extensively about climate change and existential threats, which may inadvertently foster apathy or cynicism in young minds rather than inspiring action through optimism. A significant portion of the dialogue focuses on the psychological impact of early pessimism versus optimism, particularly concerning neuroplasticity in children. The speakers discuss how reflexive systems work; for instance, telling a child that America is terrible can shape their entire youth into viewing it negatively, whereas starting with generalized positivity allows specific scrutiny to develop later as they mature. This perspective extends to parenting advice where fostering optimism and agency is seen as crucial because action flows from hope rather than despair. The discussion also touches on the concept of "unlearning," noting that undoing established beliefs or myelin sheets formed in childhood is significantly harder than initial learning, reinforcing the idea that early education should prioritize building a foundation of confidence before introducing harsh realities like power structures and systemic failures. The dialogue briefly veers into cultural comparisons between American and British self-perception, highlighting how nations often possess an insecure internal reputation despite external admiration from others abroad. The speakers joke about Americans complaining about their country's lack of patriotism while being the tallest in the room globally, contrasting this with Britons who frequently criticize themselves regarding issues like racism or capitalism even when loved internationally by other cultures. This self-defeating distortion is compared to Jack Butcher's observation that unlearning is a hundred times harder than learning, serving as a metaphor for why societies might cling to negative narratives despite evidence of their own greatness. Towards the end of the segment, the conversation transitions into a promotional discussion about hydration and electrolyte balance, specifically endorsing Element, an electrolyte drink mix designed to reduce muscle cramps, fatigue, and brain fog while regulating appetite. The speaker shares personal experience with using the product daily for five years to optimize performance during workouts or other physical activities, noting its taste profile as a sweet, salty nectar that makes a tangible difference in reducing cravings and optimizing health. The segment concludes by offering details on purchasing options, including free shipping within the US and a no-questions-asked refund policy with an unlimited duration for those who wish to try the product risk-free via their website or link provided in the episode description.

Have you seen the Retro Codex? Really, really cool website. So, it's a website that teaches you things that you learned in school that are now disproven. So, you can go in and look at what year you graduated high school and it'll tell you what you learned in school and have now been disproven. Jared, can you pull this up for me? So, um I put this in as 2000s, which would be for me and George. Uh lightning never strikes the same place twice. Uh lightning has struck several places multiple times. Empire State Building is struck approximately 25 times a year. Uh wearing red near a bull will cause it to charge. Bulls may not be able to distinguish the color red from other colors. What triggers the bull is movement and physical provocation, not color. The red cape is to conceal blood stains. Uh goldfish have a 3-second memory. Goldfish retain memories for weeks, months, and possibly years. George Washington had wooden teeth. He did wear dentures, but they were made of other materials such as tin, gold, and lead. Human teeth from enslaved individuals. It's a bit gnarly. Uh you need to wait 20 to 30 minutes after you eat to swim or you'll get stomach cramps and drown. There's no clinical evidence for that. There's another one. Go a bit further down for me. >> see. Oh, if you roll your eyes they'll get stuck. >> and folk wisdom checked on the top left. I was like, I don't recall getting >> Uh go down a bit more. If you pee in the pool, everyone will know cuz it'll turn water green. >> Hot water washing hands is not Go back up. than cold water. Yeah, right there. Interesting. I'm learning a few things. >> Water temperature has not been found to impact the antibacterial efficacy of hand washing. Uh I didn't even know that. After a person dies, their hair or fingernails can keep growing. >> Who who who thinks the Earth is the only planet with water? I don't know I don't know about that. >> But in the 2000s, might you have thought that cuz Pluto being a planet would have been true when we went to high school. >> Yeah, yeah, yeah, true. >> Uh brown sugar is healthier than white sugar. Yeah, I just thought it's it's nice to find and then obviously all of this stuff with the food pyramid, that's got turned literally upside down. >> So, some of these will end up being overturned, too. But yeah. Um oh, for sure. >> I I think when I was thinking about, you know, the way kids are educated, I think that schools do something that I think in some cases it like stay at least they traditionally that is that is maybe the right thing to do which is you teach the wrong story. The simple wrong story first just to like let the concepts and then later you start to build the nuance and you realize that the but that's a kind of like you like Thanksgiving. I think it's I I think it's I learned early on that Thanksgiving was this like wonderful thing and the pilgrims came and the the Indians at the time the Indians were like everyone was happy and they had this nice feast and or you know, just like Columbus discovered the new world but like no, he didn't but like and just like keep it let let the basic story sink seep in and then later you can be like actually like that this is like an allegory kind of for that that represents like a much larger more complicated much nastier story often and I think sometimes right now what they're doing is they're you know, out of kind of I don't know, you know, kind of political reasons or whatever they're they're they're teaching kind of very very like you know, um kind of a hardcore first story to really young kids right away that um >> They're front-loading the gnarly version. >> Yeah, exactly and maybe going too far even in that direction when like I think I think I mean I this is a whole other can of worms but I think that maybe I want to >> But but they disguise it >> I I know I think that um I do think American children should be taught first all these good right things about America. They should learn that they're in this great country that's has complicated they've not been perfect but they've done a lot of great things. Um and it's this wonderful thing and patriotism and be really proud and then later later then you can learn a lot more nuance. Or it's the same reason that I think you shouldn't be teaching your kid, you know, that like you think your dad's a good person but actually you know, he cheated when in his 20s like you know, you know, that he like did that you know, he got fired like you don't do that. You start with the dad's great of course and then later in life when the kids an adult you start I don't know this is part isn't controversial anymore. You start to then say you know, dad you know, dad can say to you, you know, yeah, I'm not perfect. I did this and this but like Yeah. >> You don't need to front load. >> Kids are kids and like it's a very different kind of person to teach. >> Well, also because I mean I remember talking to very close friend of mine who's got a bunch of kids. Wonderful guy, very successful in what he does. And I asked him what his parenting advice would be. And his first rule was you need to teach your kids to be optimists because action flows from optimism and agency flows from optimism, right? And so what you're describing sort of creates a picture that you don't want to aspire to engage with and seems antithetical to that. >> two you know, second, third, fourth graders just hammer climate change, climate change, the your future's destroyed. Like what why? Who thinks this is a good idea? >> Right. >> Little little kids. >> Well, then the older generations are like, oh my god, these younger generations are so apathetic. I'm like, yeah, you're getting waterboarded with existential threat all day, yeah. >> I guess it makes sense that the younger you are, the more neuroplastic you are, right? And even like statements like that are quite reflexive. So if if you go on if I go on the news tomorrow and say it's it's going to be a sunny day, I have no impact on whether it's going to be a sunny day. But a reflexive system is if I go on the news tomorrow and say there's going to be a bank run. I have an impact on whether there's going to be a bank run. And if you go in thinking America's a terrible country, that's going to be quite a reflexive thing for your entire youth. I mean, it's quite funny listening to an not that you were complaining but an American talk about the lack of patriotism in their country. >> of funny with two Brits next to the two of us. >> Yeah, it's kind of like Chris talking to me about like how he's frustrated with the size of his forearms right now. You know what I mean? >> I'm like, okay, okay, I understand but yeah, I think it's interesting for America to be going through that when you're still by far the tallest in the room. >> Right. Totally. >> And and by the way, there's so so much British history to be proud of. >> Oh, don't get me started. >> This negative lens >> Don't get me started, Tim. I I I I said this to Chris previously, that we are the most insecure in terms of internal reputation versus external. So, if you travel anywhere else in the world, apart from a few places, they often like love the UK. Um but internally, they often criticize themselves the most. I'll never forget a friend of mine um uh came uh his sister came home one day and she said, "You know what?" She goes, "Britain is the racist country on Earth." And he paused for a second and he just said, "Compared to what?" She couldn't answer. >> [laughter] >> It's that line about capitalism, it's the worst system apart from all of the other ones. >> Yeah. >> It's just a crazy distortion, lands, and it's so self-defeating and it's like this crazy Yeah, I Jack Butcher's got this great line. He says, "Unlearning is 100 times harder than learning." And if you're laying down those myelin sheets and some kids who's 5 years old, 6, 7, I don't know when you start to understand what climate is and what power structures look like, but yeah, you're probably best starting off with generalized optimism and getting into specific pessimism or specific scrutiny as opposed to generalized scrutiny. >> maybe, you know? Like maybe a little middle school elementary school is just is just, yeah. >> Most people don't realize how much being dehydrated impacts their performance, which is why for the last 5 years, I've started pretty much every morning with Element.
