Podcast Episode Notes: Today, Explained - Battling Brain Rot

Episode Overview

  • Title: Battling Brain Rot
  • Description: Discussion on how modern distractions, such as bland colors, AI summaries, and declining literacy, may be affecting our intelligence.
  • Hosts: Jonquilyn Hill with guest Stuart Jeffries, journalist and author of *A Short History of Stupidity*.
  • Production Team: Ariana Aspuru (Producer), Jenny Lawton (Editor), Melissa Hirsch (Fact-Checker), Patrick Boyd (Engineer).

Key Themes and Discussions

The Concept of "Brain Rot"

  • Definition: Brain rot refers to the perceived decline in intelligence due to modern distractions and technology.
  • Cultural Sentiment: A prevalent feeling among individuals that society is increasingly "dumb" in the face of information overload and technological convenience.

Perspectives on Intelligence and Stupidity

  • IQ vs. Willful Ignorance:
  • There is criticism of defining intelligence solely by IQ tests.
  • Stupidity is linked to willful ignorance—choosing not to engage one's intellect.
  • Historical Reflection:
  • The worry about stupidity is not new; it has been a subject of discussion since ancient times (e.g., Socrates addressing foolishness).

Modern Challenges to Intelligence

  • Impact of Technology:
  • AI and technology can lead to cognitive outsourcing, diminishing our ability to think critically and independently.
  • Examples include reliance on GPS for navigation, leading to a decline in spatial awareness.
  • Social Isolation:
  • Social interactions are crucial for cognitive health. Isolation leads to cognitive decline.

Views from Stuart Jeffries

  • Moral Dimension of Stupidity:
  • Stupidity is framed as a moral failure, emphasizing the importance of curiosity and critical thinking.
  • Critical Thinking:
  • Lack of engagement in politics and a critical mindset contribute to the rise of demagogues.

Neurological Insights on Memory and Learning

  • Neuroplasticity:
  • The brain's ability to change and adapt throughout life, suggesting that cognitive functions can improve with practice and engagement.
  • Memory Formation:
  • Memories are formed through the binding of sensory experiences in the hippocampus, reinforcing the need for active engagement with information.

Strategies for Reclaiming Intelligence

  • Re-engagement with Learning:
  • Active learning through historical study, critical discourse, and social interaction can enhance cognitive functions.
  • Balanced Media Consumption:
  • Reducing passive screen time (e.g., television) in favor of engaging conversations and critical thought.

Conclusion

  • Call to Action: Encourages listeners to seek social interactions, engage in learning experiences, and critically assess the information consumed daily.
  • Final Thought: Emphasis on community and shared experiences as key to cognitive vitality.

Key Takeaways

  • Modern distractions, while convenient, can lead to decreased cognitive engagement.
  • Intelligence encompasses more than just IQ; it involves a moral obligation to remain curious and critical.
  • Historical and cultural perspectives reveal that challenges to intelligence have existed throughout time.
  • Active engagement, both socially and intellectually, is essential for cognitive health and can reverse trends of "brain rot."

Additional Notes

  • Listeners are encouraged to reflect on their own consumption of media and their engagement with the world, considering how they can actively reclaim their cognitive abilities.

1:03When I'm talking, I feel dumb. We were never, and I mean never, ever, meant to hear the thoughts of this many stupid people in one day. Like, we all know we're getting dumber, right? Like, you feel it, I feel it, we all feel it.

1:20Jonquilyn Hill:As you scroll through your feeds, do you ever feel like all that brain rot is taking a toll? It's not just that. We're investing less in schools, we distrust science, and we have AI doing a lot of our thinking for us. Some people are saying we're in a golden age of stupidity. I think we are at the dawn of the golden age of stupidity. It honestly feels like at times we solve the issue of not knowing things by deciding that we don't need to know those things. We are the most informed generation in history, yet somehow the dumbest. The words stupid and dumb are thrown around a lot, and definitely in ableist ways.

2:00Jonquilyn Hill:But what we're talking about here is willful ignorance, using our minds less and allowing them to get weaker. I'm John Glyn Hill, and this week on Explain It To Me From Vox, how do we get our brains back? A lot of people have a lot of opinions on what it means to be stupid. The easy way is to say that if you get less than 100 in an IQ test, the further you are away from 100 with your score, the more stupid you are. I really want to push back against that definition. I think it's a really stupid definition because it doesn't really capture at all what we mean when we talk about stupidity. And also IQ tests themselves are pretty clumsy ways of defining stupidity.

2:43Jonquilyn Hill:How do you define it? Damn you, that's a really good question.

2:51Jonquilyn Hill:This is Stuart Jeffries. He's a journalist and he wrote a book called A Short History of Stupidity. I like this idea of it being somehow a moral thing rather than data, you know, because I think we're so ready to data and it doesn't really capture what we really value. What we value, I think, is stopping being ignorant, having a will to stop being ignorant. And if you don't have that will, that to me is stupidity. Why are we talking about this now? Why have we returned to this discussion about it? There seemed to be a lot of it around. And when COVID hit, there seemed to be a lot of people behaving in rather stupid ways.

3:31A lot of people weren't. But it seemed to be a good time because of that and because of the rise of a kind of populist demagoguery, which still appalls me, still shocks me. You know, it's like people have abandoned the very critical thinking that we need.

3:47Jonquilyn Hill:Right now, there are a lot of things that make us feel, I don't know, like kind of numb. You know, our feeds are full of slop. The Pantone colors of the year have been so bland. I'd like to announce Pantone's color of the year 2025 is shit brown. Good news, everybody. Pantone just announced its 2026 color of the year and they're going with white. Plus, we have AI summaries for everything now. Choose watch video, and the AI agent will watch the entire video in seconds and summarize it. The truth is, nobody has time. But AI does. It all just feels flat. Is that making us less smart? I don't know.

4:31I'm going to push back. I'm always going to push back a little bit against the idea that AI is screwing us over. But I really take your point. There is a sort of blandification of life. it's like we feel that we're more stupid but you know looking at the history maybe we aren't we're just we're actually just dealing as we always have done um with new kinds of technology which threaten us you know really upset us like the luddites destroy the machines because they were terrified of them now we're terrified of ai because you know maybe an existentially different threat but it is a sort of it seems similar to me we're just threatened by the the unknown and we think we're on the chasm of something, you know, of our own extinction or something like that.

5:10I kind of think it's too soon to call it. But yeah, I know what you mean. The sense of brain rot we're feeling is out there. Do you know more about modern brain rot or OG brain rot? Let's find out. Gallerina Cappuccino. Yes. Chimpanzini Bananini. Perfect. Tung tung tung sahore.

5:28Jonquilyn Hill:Yes. And there are ways our brains are working less for things, you know. For instance, I don't necessarily need to know directions. I have Google Maps on my phone. There's not really as much friction in the world for payoff. Does that impact the way we interpret and understand the rest of the world? I think, yeah, I really take that point. That sort of cognitive outsourcing where we just made our technology do the work for us. That's worrying if that's what's really happening. There's also another thing, which is that we are made to feel stupid by the bureaucracies we live in. If you ever get mired, as I always seem to, you know, two-factor recognition, authentication and all that kind of stuff, you just feel dumb all the time, even though you aren't.

6:16Even though, you know, if you're a college graduate or if you're a professor, you're going to feel dumb. So there is a sense in which you will feel dumb no matter how clever you are. I think life, living lives in, you know, technologically advanced society, it's got really complicated, perhaps too complicated.

6:35Jonquilyn Hill:You know, people say because of all of these different factors, that now we're in this golden age of stupidity. Yeah. Is that true? Do you think that is true? No, not really. What a father I would be, apart from anything else, suggesting that we're getting, you know, we're on average getting more stupid when my daughter's, you know i think cleverer than me you know she's got better opportunities better read and she's yeah you know more empathetic and kind of sweet a person than i'll ever be you know um yeah so i'm not going to say i'm not going to say that and i don't really believe it at all i you know and i look back at some of the things i was doing when i started my career you know they weren't great and i wasn't doing things that were particularly clever i think i'm cleverer and better now partly because of the technology i use that helps me to connect with people in ways that i wouldn't have been able to do when I say, you know, her age, when I was 20.

7:25Jonquilyn Hill:When we talk about stupidity, are we maybe thinking of a different kind of stupidity when we think of the era we're in now? You know, it's the lack of critical thinking, a lack of curiosity. Is that sort of where we are? Yeah, there's a fear. And you can see it in the way that people talk about how politics isn't working. People don't know the names of their representatives. They don't really get involved in politics. and that leaves the way open to demagogues of the kinds who are dominating the world at the moment. You know, yeah, you're right. There is a lack of critical thinking, but it was ever thus.

8:01You know, it's not like there was a golden age where everybody was really, you know, on top of democracy and really keen to sort of, you know, Hitler was elected, you know. I've said the H word already, but, you know, it's always worth bearing that point in mind. He was elected and by sophisticated people as well. So the suggestion that we are worse than our elders cognitively seems to me to be dubious.

8:34Jonquilyn Hill:Humans have been fretting over how smart we are and aren't for a really long time. That's next.

9:20Support for Today Explained comes from Vanta. If you run a business, perhaps you've noticed a shift. Risk and regulation are increasing, and customers want clear proof of security before they will even consider signing with you. Building that trust is essential to closing deals, says Vanta, but it's also complex, costly, and time-consuming. Vanta says they can automate that process to bring compliance, risk, and customer trust together on one AI-powered platform. They say they automate the process of achieving and maintaining compliance with over 35 security and privacy frameworks, including SOC 2, ISO 27001 and HIPAA.

9:53This helps companies get compliant fast and remain compliant, freeing up time. Instead of getting buried in audits and spreadsheets, Vanna says you get a system that runs behind the scenes, minimizing risk powering growth. Vanna says that companies such as Ramp and Writer spend 82 percent less time on audits with Vanna. Not just faster compliance, more time for your business to grow.

10:25Jonquilyn Hill:I'm J.Q. This is Explain It To Me. And I'm talking with writer Stuart Jeffries about his book, A Short History of Stupidity. Turns out, this worry of ours goes a long way back. Well, as far back as I can find, I mean, it probably goes back further. It goes back certainly to Socrates 2 ,500 years ago in Athens. He has this dialogue with this guy called Alcibiades, who's an aristocrat, very rich, very beautiful, and really, really dumb. But he's completely full of self-belief that he should become a leading politician, that he has the right stuff to guide the Athenian people through the crises. So the whole dialogue is Socrates just gently saying to him, No, you haven't.

11:11You're not very clever. You know, you're ignorant. You are wedded to stupidity, my fine friend, of the vilest kind. You are impeached of this by your own words out of your own mouth. But that's not the worst thing they can say about you. You're stupid because, you know, you don't realize that you're ignorant. And even if you did realize that you're ignorant, you wouldn't do anything about it because you're so full of pride. You are not only ignorant of the greatest things, but while not knowing them, you think that you do. So that's like 2 ,500 years ago. And to me, it would be like today.

11:52Jonquilyn Hill:You've looked at the historical understanding of stupidity through different lenses, including the Buddhist lens. What conclusions did they come to? How did they think about stupidity? Yeah, well, Taoism as well. They're just very interesting perspectives to have on how we live in the West. The implication is that we live in a stupid way because we live for our possessions. They're saying you are leading worthless lives in your pursuit of materialism. How can we live without desire and how can we live without wanting to have things and possess things? Is that something that human beings can do?

12:30You know, in a way, that's what the Buddhists are saying, and that's why their critique of how other people live, particularly us in the West, particularly us now in the decadent, materialistic West.

12:41Jonquilyn Hill:It's so interesting how the definition of stupidity can change based on what time you live in or what culture you come from. Yeah, it's a social construct. It's always a reflection of what's valued at the times in which people are talking about. So, you know, like in Shakespeare's time, all those Shakespeare's plays is full of fools. And I, that I'm sure I lack thee, may pass for a wise man. Better a witty fool than a foolish wit. But the fools are always kind of low-class people. They aren't kings. And they're always telling truth to power in a rather, you know, hidden way, in a clever, masked way.

13:21And they're talking about the value of folly. You know, the value of not being, you know, easily consumed, not being easily sort of read. That's what, you know, a lot of Shakespeare is about.

13:33Jonquilyn Hill:How did the big psychologist's understanding of stupidity shape us? You know, I'm sure Carl Jung had a lot to say about it. Yeah, I mean, there's so many intellectual revolutions where we realize that we aren't masters of our own domains. We aren't, you know, in charge of our cognitive worlds at all. nowhere more so I suppose than Freud saying that we are you know subject to our unconscious impulses or you know Jung sort of talking about the idea that there's a collective unconscious so the idea that we're all connected we're all actually part of the same being in a way and it's stupid to imagine that we're individuals who can just force our wills from other people and you know that's that's what the game's about life isn't you know life that for them isn't really about these great big narcissistic displays of human will.

14:21Jonquilyn Hill:I wonder if there are other kinds of intelligence we should be thinking about, you know, not just IQ, but EQ, emotional intelligence. Yeah, EQ is a very interesting phenomenon, very different. You know, the reason we're not talking about it and the reason it's not really written, well, it is written about, but the reason it isn't held up as a yardstick is because it's hard to measure, you know, why the stereotypes of men not talking and men being, you know, very repressed about their feelings and all of that is often a symptom of a lack of emotional intelligence, for example. How did ignorance come to be associated with evil?

14:58Jonquilyn Hill:Because, you know, there's a history there, too. Yeah, well, there was with Socrates, you know, he was saying that Alcibiade is this, you know, that young, dumb and full of stupidity guy we were talking about before. He was evil because his soul was sort of bent on doing something which he wasn't ready for. You know, he wasn't ready to lead the people of the city. You know, he shouldn't have been anywhere near politics until he understood what politics was. He cut to a courtroom in Jerusalem in 1961. New Yorker sent Hannah Arendt, who's this German-Jewish philosopher, to cover the Eichmann trial.

15:36And she looks at this guy, this architect of the Holocaust, and says to herself, this guy is stupid, by which she means, and she, you know, expands on it, evil. And there she's got the idea that she equates stupidity with evil with a lack of empathy.

15:55Jonquilyn Hill:There's nothing deep about it, nothing demonic. There's simply the reluctance to ever imagine what the other person is experiencing. He had no empathy for the people he was killing. He just didn't see them as people. And that was, for her, a form of stupidity. So evil comes in. It's like a failure of your soul in some sort of way. So who has gotten this right? Which understanding of intelligence and stupidity is the one we should be looking at, especially right now? Oh, me. Me. Of course. I don't know. I mean, if you ever come across anybody who speaks with humility about themselves, who's deprecating about themselves, that to me is such a sign of intelligence.

16:43You know, I use this example all the time when The Guardian introduced, like the New York Times did, corrections and clarifications. so for the longest time you know you'd write something and it wouldn't get corrected even if it was garbage and even if you've got the you know the gender or the age of you know basic facts wrong about a person and then suddenly there were these corrections and i remember feeling absolutely absolutely humiliated by it because it was a threat to my sort of self-esteem you know but it was really good for my soul you know really good to have that you know to be made made to feel sense of humbleness, you know.

17:20But there are people around who have a humility which I think Socrates would have recognized. I think anybody you come across who has done that walk, you know, walked into a path where they can realize that they are wrong and learn from their mistakes, that's got to be a sign of intelligence, surely.

17:43Jonquilyn Hill:Do you think we can reclaim our intelligence? Is there a way for us to turn this thing around? Yeah, why not? I mean, and the other things, studying history, my daughter's studying history, that helps, having a historical perspective on how things... You know, we feel we're in a special, doom-laden, terrible age. Perhaps we aren't. You know, perhaps actually things were much worse back in the 18th and 19th century, you know, in these eras where things were supposed to be so much better. When it comes to a sort of cynicism about the age we live in, It's the worst of all possible worlds, and things are only going to get worse.

18:21I don't see that. I don't really believe that at all.

18:29Jonquilyn Hill:All is not lost. We can reclaim our brains and make ourselves smarter. Coming up, how to do it.

20:38Jonquilyn Hill:We're back. It's Explain It to Me. I'm JQ. And this is Boston University's Andrew Budson. So I'm a neurologist and I specialize in memory disorders. Andrew studies how we make memories and how we hold on to them. He says it all starts when we notice something. That information gets stored deep in our temporal lobe, otherwise known as the hippocampus. This hippocampus, it actually takes like the separate sights and sounds and smells and thoughts and feelings that you're having at that instant, and it binds them all together into a coherent whole. it then gets tagged with an index that will allow you to retrieve that information later.

21:28Jonquilyn Hill:Is it like a filing cabinet? Because that's what I imagine. I'm like the little, I don't know, inside out people in my brain, like reaching into the files and pulling stuff out. Oh, here's one where she waved at a guy who was actually waving at a girl behind her. Oh, that was so bad. Good choice. Oh, here's when she forgot that girl's name. Oh yeah, that was super awkward. What was her name? You know, it's a little bit like a file cabinet, but the twist is that the files are just the blueprints or the schematic of the memory. And what your brain needs to do is it needs to take this blueprint and it needs to very actively recreate the memory.

22:16It needs to actively recreate all the details that are going on. So there, another part of your brain called the frontal lobes get involved. And they are sort of like the director or the contractor that is in charge of this active construction. So to sort of get all of these pieces to be working together. And when we retrieve the memory and actively reconstruct it, it reproduces the pattern of neurochemical electrical activity that it had when that episode was originally created.

23:00Jonquilyn Hill:Biologically, what allows us to learn and retain new ideas? So it's one of the coolest things, and it really is part of neuroplasticity. So neuroplasticity is essentially the concept that our brains are elastic, or they're able to make new connections over time. So memories are a strengthening of existing connections in the brain between one neuron and another, and they're also the creation of new connections between neurons in the brain. And so what happens when we sleep is the brain figures out, okay, this strengthening of connections here, this is an important memory, so we're going to strengthen in that even further, or we're going to grow new connections.

23:56So those connections become permanent. And one of the really cool things about neuroplasticity is how it's something that people can use throughout their lives. When I went to medical school, I was told that it was really only, you know, like babies and children that had this sort of neuroplasticity available to them. But we now know that neuroplasticity is going on throughout the lifespan, including in people as old as me and older. Yeah.

24:36Jonquilyn Hill:So it sounds like our brains are a muscle like any other. And so is it one of those use it or lose it type situations? That is very true. And there have been studies that have looked at what happens when people get socially isolated. Our brains evolve for social interactions. Our math teachers might think it's to do arithmetic in our heads, but they're wrong. That's not what our brain is for. So when you're like talking to your friend next to you in the math class, that is actually what our brains are for. They're for these social interactions. And so people who become socially isolated, their brains actually shrink.

25:24Even if they don't have a disorder, their brains shrink. And people who are socially isolated are at increased risk of developing dementia.

25:35Jonquilyn Hill:Okay, so if your brain is a muscle, does that mean we can train it to be smarter? Absolutely. We totally can. And the key is to train with the most direct example as you possibly can. So what I mean by that is there are a lot of companies that are out there, many of whom are working very hard with lots of scientists to try to develop brain training games that are going to really help us. But so far, what the studies have proven is that if you spend a lot of time with these brain training games, you get better at the brain training games. You know, it does not translate into everyday life. But, like, if you want to get better at doing something like, you know, remembering, you know, French vocabulary words, you can get better at remembering French vocabulary words by basically working hard at, you know, developing sort of a routine or a program as to how you're going to work on studying the vocabulary words, how you're going to incorporate it into your life.

26:58So we all can improve on almost anything our brain does, but the trick is to work on practicing that.

27:11Jonquilyn Hill:Yeah, you know, people have written and talked about how it can be difficult to focus and think critically these days. How does critical thinking and knowledge develop? You know, I actually think that critical thinking is a skill. And I don't know that I have a simple recipe, but I think it has to do with when you're faced with a complicated decision or something complicated that you're trying to do or achieve or create, of sort of slowing down, of listing all the different things that you know, listing what is the output that you want to have, what's the final product, and then going through and thinking about all the different possibilities so that you won't miss something that's important.

28:12And often, Another thing that happens when we sleep is we allow our unconscious brain processes to work on problems. So I think critical thinking is really the conscious part of it, but we want to use our unconscious mind as well, because often we can get insights when we sleep.

28:35Jonquilyn Hill:Yeah, you know, before I let you go, I'm curious your thoughts on something. There's all this talk about how like, oh, we're not as smart as we used to be. I don't know, you look at a lot of brains. Like, how are we stacking up these days? Yeah, so, you know, I do think that there are some reasons that we may not be as smart today as we used to be. I think the average person's ability, for example, to navigate from one place to another has been dramatically reduced by the use of Google Maps and other programs like that. The part of our brain that's involved in navigation does actually shrink for many people.

29:24The one other thing I'd like to mention, because it was actually studied, is that people who spend more than an hour a day watching TV actually end up getting less smart over time.
