Professor of electrical engineering and computer science Ben Recht joins us to defend Bayesianism, AI doom, and assure us that the statisticians have everything under control. Just kidding. Recht might be even more suspicious of these things than we are. What has statistics ever done for us, really? When was the last time YOU ran a clinical trial after all, huh? HUH? After Ben Chugg defends his life decision to do a PhD in statistics, we talk AI, cults, philosophy, Paul Meehl, and discuss Ben Recht's forthcoming book, The Irrational Decision. Check out Ben's blog, website, and his story about machine learning. We discuss Ben Recht's theory of blogging Why is Berkeley the epicenter of AI doom? Where the word "robot" came from Is Bayesian reasoning responsible for AI doom? Paul Meehl and his contributions to science Ben Recht's bureaucratic theory of statistics What on earth is null hypothesis testing? What is the point of statistics?

Phlogiston? Elan Vital? Caloric? Mention of any of these at a party, and Neil DeGrasse Tyson will be sure to take you out back and kick you in your essences. So why do "essences" have no place in science? In this episode we explore that question (and dive into some of the history behind this debate) by reading Chapter 6 of Conjectures and Refutations: A Note On Berkeley As Precursor Of Mach And Einstein. In one corner, we have the estimable Sir Isaac Newton and Roger Coates (and of course Andre the Giant, upon whose shoulders they are standing), and in the other, we have Bishop Berkeley and Ernst Mach, looking to throw down at the speed of sound. Berkeley can't get Newton and his forces out of his head (literally), and boy oh boy is the fight ever on. We discuss How should teachers address the "students using ChatGPT to write their essay" problem? Can we learn a bit from Stalin here? Is Ben basically Gandhi? (Answer: Yes of course) How can one be both an idealist and an empiricist? WTF is a 'force'??? Instrumentalism and Essentialism The history of the debate between Berkeley and Newton The lifelong feud between Ernst Mach and Ludwig Boltzman What's the difference between essences and unobservables? Is Mach a filthy plagiarist? Who won the essentialism vs instrumentalism debate? (Answer: Neither side won. Popper won.) References Go amuse yourselves and watch some videos of Newton's spinning bucket thought experiment. Boltzmanns Atom: The Great Debate That Launched A Revolution In Physics Quotes Everybody who reads this list of twenty-one theses must be struck by their modernity. They are surprisingly similar, especially in the criticism of Newton, to the philosophy of physics which Ernst Mach taught for many years in the conviction that it was new and revolutionary; in which he was followed by, for example, Joseph Petzold; and which had an immense influence on modern physics, especially on the Theory of Relativity. Popper, C&R Chapter 6 (20) A general practical result—which I propose to call ‘Berkeley’s razor’—of this analysis of physics allows us a-priori to eliminate from physical science all essentialist explanations. If they have a mathematical and a predictive content they may be admitted qua mathematical hypotheses (while their essentialist interpretation is eliminated). If not, they may be ruled out altogether. This razor is sharper than Ockham’s: all entities are ruled out except those which are perceived. Popper, C&R Chapter 6 No attempt was made to show how or why the forces acted, but gravitation being taken as due to a mere "force", speculators thought themselves at liberty to imagine any number of forces, attractive or repulsive, or alternating, varying as the distance,[4] or the square, cube, or higher power of the distance, etc. At last, Ruđer Bošković[5] got rid of atoms altogether, by supposing them to be the mere centre of forces exerted by a position or point only, where nothing existed but the power of exerting a force.[6] https://en.wikipedia.org/wiki/Imponderable_fluid Mach's antipathy to theorizing and to the invocation of "metaphysical" and therefore unprovable notions led him to some extreme opinions. In The Conservation of Energy he remarks: "We say now that water consists of hydrogen and oxygen, but this hydrogen and oxygen are merely thoughts or names which, at the sight of water, we keep ready to describe phenomena which are not present but which will appear again whenever, as we say, we decompose water. David Lindley, Boltzmann's Atom In Mach's world, there was to be no such thing as "explaining" in the way scientists had always understood it. Mach even went so far as to argue that the traditional notion of cause and effect-that kicking a rock makes it move, that heating a gas makes it expand —was presumptuous and therefore to be denied scientific status. David Lindley, Boltzmann's Atom But it was not always so. Well into the latter half of the 19th century, most scientists saw their essential task as the measurement and codification of phenomena they could investigate directly: the passage of sound waves through air, the expansion of gas when heated, the conversion of heat to motive power in a steam engine. A scientific law was a quantitative relationship between one observable phenomenon and another. David Lindley, Boltzmann's Atom Errata Vaden incorrectly said this that this essay was referenced in Mach's wikipedia page. Wrong! Fool!

Ben and Vaden test their French skills and have Hugo Mercier on the podcast to discuss who we trust and what we believe. Are humans gullible? Do we fall for propaganda and advertising campaigns? Do we follow expert consensus or forge ahead as independent thinkers? Can Vaden go for one episode without bringing up Trump? Hugo Mercier is a research director at the CNRS (Institut Jean Nicod, Paris), where he work with the Evolution and Social Cognition team. Check out his two books: The Enigma of Reason and Not Born Yesterday . We discuss Mercier's thoughts on the cognitive bias literature Open vigilance mechanisms Criticism of the System 1 vs System 2 dichotomy Why Kahneman misinterpreted the bat and the ball thought experiment Do flat earthers really believe the earth is flat? The Asch conformity experiment Preference falsification vs internalization of professed beliefs How important is social signaling? Trump, MAGA, gullibility, and Tariffs How effective are advertisements? How effective is propaganda? Is social science reforming?

We all knew that Vaden would release his inner Youtube debate bro at some point. Well he finally paid Ben enough to do it, and here we are: our first reaction video. Today we're commenting on the video What's the most rational way to know?, a discussion between Brett Hall and Peter Boghossian on the relationship between confidence and evidence. Are we overly confident in our ability to make reaction videos? Evidently. Check out more from Brett Hall here and Peter Boghossian here. We discuss What is the relationship between confidence and evidence? The "formal apparatus of science" vs the "sociology" of science Eddington's famous experiment Why confidence and belief can't be mathematized (But why they are useful nonetheless) Confidence as a function of falsifying experiments Bayesianism vs critical rationalism References Paper discussing how it took the wider scientific community over 40 years (after Eddington's experiment!) to become convinced in the truth of general relativity: The 1919 measurement of the deflection of light Eddington's original paper: Vaden and Brett's blog exchange Socials Follow us on Twitter at @IncrementsPod, @BennyChugg, @VadenMasrani Come join our discord server!

Round two on the anxious generation. Well, honestly, round three. But we had a false start with round two, which is why this episode is a little late in coming. If you want to hear the gory, data-heavy details of our second attempt, you can access the episode by becoming a patron (was there ever a better sell?). We discuss Whether the rise in self-harm rates was due to reporting changes Whether education and common core could be affecting mental health Whether cultural pessimism is on the rise Cyberbullying Martin Gurri's thesis on the digital revolution How Vaden will handle social media with his kids References David Wallace Wells opinion piece Our patreon episode on David Wallace Wells' thesis Peter Gray on common core Revolt of the Public Errata Ben said The Revolt of the Public was written in 2014. It was written in 2018. Vaden said he would list all four of Haidt's points about why girls are uniquely vulnerable to negative effects of social media, and only got halfway in before forgetting he said that. The four reasons Haidt gives are: Girls are more affected by visual social comparison and perfectionism Girls' aggression is more relational Girls more easily share emotions and disorders Girls are more subject to predation and harassment Quotes Here is a story. In 2007, Apple released the iPhone, initiating the smartphone revolution that would quickly transform the world. In 2010, it added a front-facing camera, helping shift the social-media landscape toward images, especially selfies. Partly as a result, in the five years that followed, the nature of childhood and especially adolescence was fundamentally changed — a “great rewiring,” in the words of the social psychologist Jonathan Haidt — such that between 2010 and 2015 mental health and well-being plummeted and suffering and despair exploded, particularly among teenage girls. For young women, rates of hospitalization for nonfatal self-harm in the United States, which had bottomed out in 2009, started to rise again, according to data reported to the C.D.C., taking a leap beginning in 2012 and another beginning in 2016, and producing, over about a decade, an alarming 48 percent increase in such emergency room visits among American girls ages 15 to 19 and a shocking 188 percent increase among girls ages 10 to14. Here is another story. In 2011, as part of the rollout of the Affordable Care Act, the Department of Health and Human Services issued a new set of guidelines that recommended that teenage girls should be screened annually for depression by their primary care physicians and that same year required that insurance providers cover such screenings in full. In 2015, H.H.S. finally mandated a coding change, proposed by the World Health Organization almost two decades before, that required hospitals to record whether an injury was self-inflicted or accidental — and which seemingly overnight nearly doubled rates for self-harm across all demographic groups. Soon thereafter, the coding of suicidal ideation was also updated. David Wallace Wells, https://www.nytimes.com/2024/05/01/opinion/smartphones-social-media-mental-health-teens.html Studies confirm that as adolescents moved their social lives online, the nature of bullying began to change. One systematic review of studies from 1998 to 2017 found a decrease in face-to-face bullying among boys but an increase among girls, especially among younger adolescent girls.[47] ... According to one major U.S. survey, these high rates of cyberbullying have persisted (though have not increased) between 2011 and 2019. Throughout the period, approximately one in 10 high school boys and one in five high school girls experienced cyberbullying each year.[49] In other words, the move online made bullying and harassment a larger part of daily life for girls. \ - Haidt, The Anxious Generation p. 170 Socials Follow us on Twitter at @IncrementsPod, @BennyChugg, @VadenMasrani Come join our discord server!
