Scott shares his monthly collection of interesting links from around the internet, covering topics from Jeremy Bentham's linguistic legacy to AI developments, with characteristic commentary and fact-checking caveats. Longer summary
This is Scott's monthly 'Links' post, a curated collection of interesting articles, studies, and social media posts from around the internet. The links span a wide range of topics including historical curiosities (Jeremy Bentham's word inventions, beard-wearing persecution in 19th century America), scientific oddities (a mushroom that causes gnome hallucinations), AI developments (mathematical proofs, constrained writing, dating apps), current events (Berkeley's housing permits, GLP-1 weight retention), and cultural phenomena (the Monet/AI art prank). Scott includes his typical epistemic disclaimers about not having verified all links independently and provides commentary throughout. The post ends with a note that he accumulated too many links and will publish the second half next week. Shorter summary

Scott reviews the state of prediction markets after explosive growth, finding that most volume is degenerate sports gambling rather than useful forecasting, and proposes both technical solutions and two potential futures for the field. Longer summary
Scott Alexander examines the current state of prediction markets after their recent explosion in popularity, noting that while volume has grown from millions to billions per month, most of it comes from sports betting rather than the epistemic improvement he'd hoped for. He explores several problems: markets aren't asking the most important questions society needs answered; resolution criteria disputes ("rulescucking") create controversy; and there are concerns about insider trading and manipulation. He proposes solutions including a novel approach to conditional markets and suggests two paths forward: either creating user-generated, subjectively-resolved real-money markets (the "Siskind Cube"), or accepting that prediction markets' main value may be as training data for AI forecasters that could make the markets themselves obsolete by late 2026.

A book review exploring the history of Project Xanadu, Ted Nelson's pioneering but ultimately unsuccessful vision for a hypertext-based internet system that preceded and differed significantly from the World Wide Web. Longer summary
This book review traces the fascinating history of Project Xanadu, Ted Nelson's ambitious vision for a hypertext-based internet system that predated and rivaled the World Wide Web. Starting with Vannevar Bush's 1945 concept of the memex, through Doug Engelbart's groundbreaking demos, to Nelson's decades-long quest to build Xanadu, the post explores how this alternative vision for the internet - featuring bidirectional links, embedded content, and built-in attribution - ultimately failed to materialize despite its early start and innovative ideas. The review ends by questioning whether the simpler Web we got instead, built by Tim Berners-Lee, might have cost us something valuable in terms of how we connect and share information online.

Scott Alexander argues against Erik Hoel's claim that the decline of 'aristocratic tutoring' explains the perceived lack of modern geniuses, offering alternative explanations and counterexamples. Longer summary
Scott Alexander critiques Erik Hoel's essay on the decline of geniuses, which attributes this decline to the loss of 'aristocratic tutoring'. Scott argues that this explanation is insufficient, providing counterexamples of historical geniuses who weren't aristocratically tutored. He also points out that fields like music, where such tutoring is still common, still experience a perceived decline in genius. Scott proposes alternative explanations for the apparent lack of modern geniuses, including the increasing difficulty of finding new ideas, the distribution of progress across more researchers, and changing social norms around celebrating individual brilliance. He suggests that newer, smaller fields like AI and AI alignment still produce recognizable geniuses, supporting his view that the apparent decline is more about the maturity and size of fields than about educational methods.

Scott Alexander explores the universal human drive for discovery and knowledge-seeking, comparing it to 'intellectual minor leagues' and questioning how non-experts can contribute meaningful insights. Longer summary
Scott Alexander reflects on Adrian Hon's article about QAnon and alternate reality games, exploring the human drive for discovery and knowledge-seeking. He argues that this drive isn't limited to conspiracy theorists but is present in all of us, including academics and bloggers. Scott discusses how people satisfy their intellectual curiosity in a world where most significant discoveries have already been made, comparing it to 'intellectual minor leagues'. He considers various explanations for how non-experts can still contribute meaningful insights, such as the vastness of knowledge, unique combinations of experiences, or repackaging existing ideas. The essay concludes by questioning the author's own role in knowledge production and suggesting that the discovery drive is a fundamental human trait. Shorter summary

Scott examines how the 5-HTTLPR gene was wrongly linked to depression for years, discussing the implications for psychiatric research and genetic testing products. Longer summary
This post discusses the history and eventual debunking of the 5-HTTLPR gene's supposed role in depression. Initially, numerous studies claimed to find links between 5-HTTLPR and various mental health conditions, interactions with stress, and even antidepressant efficacy. However, a recent large-scale study by Border et al. found no evidence for these claims, suggesting that hundreds of previous studies were likely false positives. The post explores the implications of this finding, including concerns about the reliability of psychiatric research, the tendency for studies to reinforce existing beliefs, and the questionable validity of pharmacogenomic testing products that rely on genes like 5-HTTLPR.

Scott Alexander argues that Free Energy/Predictive Coding and Perceptual Control Theory are fundamentally the same, and proposes using PCT's more intuitive terminology to help understand FE/PC. Longer summary
Scott Alexander compares two theories of cognition and behavior: Free Energy/Predictive Coding (FE/PC) and Perceptual Control Theory (PCT). He argues that while they've developed differently, their foundations are essentially the same. Scott suggests that understanding PCT, which he finds more intuitive, can help in grasping the more complex FE/PC. He provides a glossary of equivalent terms between the two theories and gives examples to illustrate how PCT's terminology often makes more intuitive sense. The post concludes by discussing why FE/PC is more widely used despite PCT's advantages in explaining certain phenomena, and suggests teaching both terminologies to aid understanding. Shorter summary

Scott examines the relationship between altitude and obesity, then explores and ultimately dismisses the theory that increased atmospheric CO2 could be causing the obesity epidemic. Longer summary
Scott Alexander explores the correlation between altitude and obesity rates in the US, noting that people living at higher elevations tend to be less obese. He discusses various studies on altitude anorexia and hypoxia's effect on weight loss.
