Scott reflects on how COVID-19's massive death toll of 1.2 million Americans has been overshadowed in public discourse by more controversial but less significant aspects of the pandemic. Longer summary
Five years after COVID-19, Scott Alexander reflects on how public discourse focuses on controversial aspects of the pandemic (lockdowns, masks, vaccines) while largely ignoring its staggering death toll of 1.2 million Americans. He points out this is the highest-fatality event in American history, surpassing the Civil War by 50%. Scott suggests this blind spot comes from two factors: dead people can't advocate for themselves, and controversy sells better than tragedy. He draws parallels with charity discourse, where controversial stories overshadow the actual lives saved. Shorter summary

Scott Alexander presents evidence against the existence of advanced Ice Age civilizations, particularly those rivaling ancient Egypt or 1700s Great Britain. Longer summary
Scott Alexander argues against the existence of advanced Ice Age civilizations, categorizing potential claims into three levels of advancement: Stonehenge-like, Egyptian-like, and 1700s Great Britain-like. He presents three main arguments: the lack of archaeological sites that would survive sea level rise, the absence of evidence for early crop and livestock domestication, and the lack of elevated lead levels in ice cores and human bones from that period. While he doesn't completely rule out Stonehenge-level civilizations, he finds strong evidence against more advanced societies. The post concludes with probability estimates for future discoveries of pre-11,000 BC structures at different levels of sophistication. Shorter summary

Scott Alexander argues that the media's failure in coronavirus coverage was not about prediction, but about poor probabilistic reasoning and decision-making under uncertainty. Longer summary
This post discusses the media's failure in covering the coronavirus pandemic, arguing that the issue was not primarily one of prediction but of probabilistic reasoning and decision-making under uncertainty. Scott Alexander argues that while predicting the exact course of the pandemic was difficult, the media and experts failed to properly convey and act on the potential risks even when the probability seemed low. He contrasts this with examples of good reasoning from individuals who took the threat seriously early on, not because they were certain it would be catastrophic, but because they understood the importance of preparing for low-probability, high-impact events.

The post explores how correlated variables can diverge at extreme values, applying this concept to happiness measures and moral systems. Longer summary
This post explores the concept of 'tails coming apart' and its application to various domains, particularly morality. The author begins by discussing how strongly correlated variables can diverge at extreme values, using examples like grip strength vs. arm strength. He then applies this concept to happiness, showing how different measures of happiness (e.g., life satisfaction, positive emotions) can lead to different countries being ranked as 'happiest'. The post extends this idea to morality, arguing that while different moral systems may agree in everyday situations, they diverge dramatically when taken to extremes. The author suggests that this divergence poses challenges for developing moral systems that can handle transhuman scenarios. Shorter summary

Scott Alexander examines conflicting narratives about cancer treatment progress, analyzing data to show that while some improvements are due to social factors, there's evidence of genuine advancements in cancer treatment and outcomes. Longer summary
This post examines the progress made in the 'War on Cancer' by analyzing cancer incidence rates, mortality rates, and five-year survival rates. Scott Alexander explores two competing narratives: one suggesting significant progress and another claiming limited success. He delves into the data, considering factors like age adjustment, smoking trends, and early detection biases. The analysis reveals that while some improvements are due to social factors like reduced smoking, there's evidence of genuine progress in cancer treatment. Stage-specific survival rates have improved, and studies adjusting for various confounders still show advancements. The post concludes that while progress may not meet the grand expectations set in the past, there has been a gradual but real improvement in cancer treatment and outcomes. Shorter summary

Scott Alexander examines whether psychiatrists should test for lead more often, concluding that while it could be relevant in some cases, there's not enough evidence to justify universal testing. Longer summary
Scott Alexander discusses the question of whether psychiatrists should test for lead more often in patients with mental health issues. He presents a case where lead poisoning was found to be a factor in a patient's psychiatric symptoms, and explores the broader implications of this. Scott then examines the complexities of deciding which potential factors to test for in psychiatric practice, given the numerous possible causes of depression and other mental health issues. He argues that while lead could be a factor in some cases, there's insufficient evidence to justify universal testing. He also discusses the challenges of interpreting and acting on test results, especially when they fall within normal ranges. Scott concludes by reflecting on different approaches to medical practice and the difficulties of balancing evidence-based guidelines with emerging theories and individual clinical judgment.

Scott Alexander examines self-serving bias and status quo defense using Oregon's gas station law change, arguing for better rational debate skills to navigate societal changes. Longer summary
This post discusses the self-serving bias through the lens of Oregon's recent law allowing self-service gas stations in some areas, which sparked outrage among some Oregonians. Scott Alexander uses this example to explore how people tend to defend the status quo and view changes as potentially catastrophic, even when those changes are normal elsewhere. He extends this idea to various fields, including medicine, child-rearing practices, and social norms. The post argues that we often rely on intuitions about absurdity to make judgments, but these intuitions can vary greatly between cultures and even states. Scott suggests that this reliance on intuition is concerning because it means that if something loses its 'protective coating of absurdity,' we must resort to rational debate to defend it - a process our society isn't particularly good at. He concludes by encouraging readers to apply the same level of scrutiny to their own beliefs that they would expect from Oregonians questioning their gas station laws. Shorter summary

Scott Alexander challenges the popular interpretation of the Rat Park study, arguing that addiction is not solely caused by poor environments and emphasizing genetic factors in addiction susceptibility. Longer summary
Scott Alexander critiques the 'Rat Park' study and its popularized interpretation that drug addiction is primarily caused by poor social environments. He presents historical examples of addiction in seemingly happy or fortunate individuals, such as Ogedei Khan and Native Americans, to challenge this view. The post then discusses the genetic factors in addiction, citing twin studies and known genetic markers. Scott acknowledges that unhappiness likely contributes to drug use but argues that the relationship between environment and addiction is more complex than the Rat Park model suggests. He proposes a toy model where other sources of reward can help resist drug addiction, but maintains that biological interventions like deregulating suboxone and researching psychedelic therapy are more immediately effective for helping addicts.
