Taleb: "standard deviation is not how much something moves on average." ask anyone - even statisticians, even government agencies - and that's exactly the wrong definition you'll get back. what they're describing is mean absolute deviation. real standard deviation squares the moves first - which quietly hands almost all...

No author has shaped my worldview more than Nassim Taleb (Nassim Nicholas Taleb). I stumbled on The Black Swan eight years ago, then inhaled the rest of the Incerto. I've increasingly come to appreciate the importance of its ideas to prolonging the human story. Was an honour to speak with Nassim on the podcast. Hard to summarise our conversation, but the timestamps below capture the gist. Enjoy! Timestamps: (0:00:55) - Heuristics for knowing when you're in Mediocristan versus Extremistan. (0:06:06) - Are certain tail exponents intrinsic? (0:10:30) - Why hasn't Universa's tail hedging strategy now been fully priced in? (0:11:52) - Does the power law distribution of startup returns mean VCs should concentrate their bets, or spray and pray? (0:15:20) - Nassim's 30-minute take on the field of behavioural economics. (0:48:57) - Nassim's 20-minute take on superforecasting. (1:11:03) - The Precautionary Principle and AI. (1:17:28) - What are LLMs doing? (1:23:10) - War, violence, & "the empirical mean is not the real mean". (1:39:17) - Covid, & how Western governments think about tail risk. (1:43:38) - What's the most important thing people in social science get wrong about correlation? (1:52:58) - How does Nassim explain the perspicacity of the Russian school of probability? (1:55:56) - Why doesn't Hayek's knowledge argument extend to prediction markets? (1:58:26) - If mean absolute deviation is a better measure than standard deviation, why has the latter become commonplace? (2:01:09) - Nassim's next book, and what he's up to at the moment.

Marc Andreessen says raw intelligence might be the worst qualification for leadership — and it changes everything about how we should think about AI. "If the leader is more than one standard deviation of IQ away from the followers, it's a real problem." Andreessen points to the US military, one of the earliest and most rigorous adopters of IQ testing, as the source of this insight. They slot people into specialties and leadership roles based on IQ scores. And over the years, they kept seeing the same pattern. A leader who is significantly less intelligent than their people struggles to model how those people think. That part is intuitive. But the reverse turns out to be equally true. "It's actually very hard for very smart people to model the internal thought processes of even moderately smart people." A leader who is two standard deviations above the norm of the organisation they're running also loses theory of mind, that ability to hold an accurate model of what's happening inside someone else's head. The gap is too wide in both directions. Andreessen then takes this to its logical conclusion: "If you had a person or a machine that had a thousand IQ or something like it, its understanding of reality would be so alien to the people or the things that it was managing that it wouldn't even be able to connect in any sort of realistic way." An AI that vastly outthinks every human in the room isn't positioned to lead those humans. It's positioned to be completely incomprehensible to them. Leadership has never really been an intelligence problem. It's a connection problem. And no amount of raw intelligence closes that gap — past a certain point, it only widens it. The world will not be run by the smartest thing in the room for a long time. Maybe ever.

This guy is making +1% on EVERY TRADE Sounds small, I know. But he already made $50k profit (started with $200 only) How? He repeats this +1% trade 30 times per day. Almost zero risk. And I found a way to make 100x more trading same markets. This is either genius or it should be illegal. But this trader has been quietly running the cleanest strategy on Polymarket for months. Just one repeatable process: > Find markets where the outcome is already decided > Buy shares at 95-99¢ > Collect the gap to $1.00 at resolution > Wake up tomorrow and do it again His PnL curve looks like a savings account that somehow prints 33% daily. Wallet: 5% per trade sounds boring until you run the parlay math. Here's exactly what changes with PolyParlay: Standard bond trading on $1,000: > 4 markets at 96¢ traded separately > +4% collected four times > Total: $1,060 (you made $60, congrats) Same $1,000 combined into one parlay: > 0.96 × 0.96 × 0.96 × 0.96 = boosted PnL > 1.27x payout multiplier > Total: $1,270 in one single position Now add 2 mispriced entries at 70-80¢ into that same parlay: > Payout multiplier jumps to 3-10x > Same $1,000 becomes $3,000-$10,000 after all hit That's the gap between grinding $160 daily and waking up to $3,000+ on the same capital. Bond markets eliminate the risk. Parlay structure eliminates the ceiling. Both together is what $50k months actually look like. Parlay bot link: This is the only bot for Polymarket parlay trading. Zero stress. Daily yield. Exponential upside.

Dr. Jared Cooney Horvath just delivered the brutal truth parents and educators need to face: “Even in schools, it doesn’t matter what the size of the screen is… and it doesn’t matter who bought it… All of these things are going to hurt learning, which in turn are going to hurt our kids’ cognitive development.” His core warning: Gen Z is the first modern generation to be less cognitively capable than their parents — despite more years in school. Attention, memory, literacy, numeracy, executive function, even general IQ — all declining. The culprit isn’t school itself. It’s the widespread introduction of screens and digital tools for learning. Across 80 countries, once tech floods classrooms, performance drops sharply. Kids using computers ~5 hours/day for schoolwork score over 2/3 of a standard deviation lower than those who rarely touch tech. US NAEP data mirrors it: states adopt 1:1 devices → scores plateau, then fall. The biological reality: Humans evolved to learn deeply from other humans, not screens. Screens circumvent the natural mechanisms of attention, memory consolidation, and deep processing. When the tool fails to deliver, we don’t remove it — we redefine success to fit the tool (e.g., SAT reading comprehension reduced to skimming short sentences instead of deep passages). That’s not progress. That’s surrender. The cost is a generation losing cognitive sharpness at the exact moment the world needs them sharpest. Parents, teachers, policymakers: How much longer do we let screens dictate what “learning” looks like?

John Spencer, Richard Kemp, and Andrew Fox are experts in the field of urban warfare, and I detail their findings in my new book, Israel on Trial: Examining the History, the Evidence, and the Law. In urban warfare, the average militant-to-civilian casualty ratio is about 1 to 9, meaning one militant killed for every nine civilians killed. That's not because every war that's ever been fought is a genocide. It's because war is horrible and urban warfare in particular is horrible. That's why Israel would much prefer to fight Hamas out in the open. It's Hamas who chooses to fight in Gaza underneath its civilian population precisely to increase—not decrease—the number of civilian casualties. In the American war in Iraq and Afghanistan, we and our allies set the gold standard. We had a militant-to-civilian kill ratio of about one to four-and-a-half, maybe one to five, and many experts believed no army would ever be able to meet that standard again. In much more difficult and complicated circumstances, Israel, even if you believe Hamas's bogus numbers—which you should not believe for all the reasons I lay out in the book—but even if you took Hamas at completely face value and you believed all of their numbers, Israel has a militant to civilian kill ratio of about one to one-and-a-half in Gaza. If Israel has committed genocide in Gaza, then the Americans committed genocide in Iraq and Afghanistan, then the Americans and the allies committed genocide in Germany and Japan, and literally every war that has ever been fought in human history has been a genocide. That's not what genocide means. We should reserve the label for the crime of all crimes, because otherwise the consequences will be dire.

Elon Musk: Something's wrong with the press. Citizen journalism is the future. “The far-left press has been going on and on about how Trump is like Hitler, Mussolini and Stalin combined, and you rolled them all into one, and he's somehow worse than all three of them combined. These are people who have killed tens of millions of people. Something's wrong with the press, guys. Journalism is dead. What the heck is going on? It's bizarre. That's why 𝕏 is the future. It's citizen journalism, where you hear from the people, it's by the people, for the people. That's what it's all about. I think this is a super, super big deal, and it's absolutely fundamental and transformative that the people actually get to decide the news and the narrative and what matters. The legacy media is basically controlled by a handful of editors-in-chief. That's it. They decide what's going to get published. That's why I really encourage everyone out there to write stuff on the 𝕏 platform and other platforms too. But citizen journalism is the future. That's where you get to hear from actual experts in the field, people who are experts in any given industry. And you get to hear the rebuttal. If somebody says something that's wrong or requires more context people can add that. 𝕏 has got community notes, which is great. Community notes, I think, got a very good batting average. It's not perfect, but it's got a very good batting average.” Lancaster, Pennsylvania, October 26, 2024
