Scott Alexander proposes that political hyperpartisanship might be a form of trauma, comparing PTSD symptoms to behaviors observed in political extremists. Longer summary

Scott Alexander explores the idea that political extremism might be a form of trauma. He compares symptoms of PTSD to behaviors observed in politically hyperpartisan individuals, such as triggers, distorted cognitions, and hypervigilance. The post discusses how trapped priors in the brain might explain both cognitive and emotional aspects of political extremism. Scott also considers the implications of framing political partisanship as trauma, including potential risks of expanding the concept of trauma. Shorter summary

Scott examines 'critical windows' in human development, comparing them to AI learning processes and discussing their mysterious nature. Longer summary

Scott Alexander explores the concept of 'critical windows' in human development, using examples from sexuality and food preferences. He compares these to trapped priors in AI learning, suggesting that children's higher learning rates might explain why early experiences have such lasting impacts. However, he notes that this doesn't fully explain the unpredictable nature of preference-changing events, and concludes that while these events seem more common in childhood, they remain largely mysterious.

Scott Alexander explores various explanations for why some people don't respond to 'woo' practices, questioning whether non-responders are defective or if woo itself might be ineffective or even harmful. Longer summary

Scott Alexander discusses the concept of 'woo' (alternative wellness and spirituality practices) and explores different possibilities for why some people might not respond to these practices. He presents four possibilities: 1) Woo is universally great but harder for some people due to being 'dissociated from bodily experiences', 2) Different people process emotions differently and woo works better for some than others, 3) Woo treats a specific defect of storing emotions in the body, and 4) Woo correlates with a specific defect but doesn't actually help. Scott provides evidence and counterarguments for each possibility, drawing on psychological theories, cross-cultural observations, and personal anecdotes. He concludes by highlighting the difficulty in determining whether practices like woo are helpful coping mechanisms or potentially harmful risk factors for mentally unhealthy individuals.

Scott Alexander examines a theory proposing that depression, anxiety, and trauma are characterized by low precision of sensory evidence, leading to overreliance on negative priors. Longer summary

Scott Alexander discusses a paper by Van der Bergh et al. that proposes a unified theory of negative emotionality, including depression, anxiety, and trauma. The theory suggests that these conditions are characterized by a processing style that assigns unusually low precision to sensory evidence, leading to an overreliance on negative priors. Scott explores the implications of this theory, including its support for various psychotherapies, somatic therapies, and meditation. He also discusses potential pharmacological interventions and how this model ties together various concepts in psychiatry and predictive processing. Shorter summary

Scott Alexander reviews 'The Body Keeps The Score', a book on PTSD, praising its historical context but criticizing its outdated science and uncritical embrace of alternative therapies. Longer summary

Scott Alexander reviews 'The Body Keeps The Score', a book about post-traumatic stress disorder (PTSD) by Bessel van der Kolk. The review covers the book's historical context, its insights into PTSD symptoms and neurobiology, and its treatment recommendations. Scott praises the historical accounts of PTSD recognition but criticizes the book's outdated scientific claims, lack of consideration for genetic factors, and uncritical enthusiasm for alternative therapies. He notes the book's emphasis on bodily disconnection in PTSD patients and the importance of reconnecting with the body in treatment. Overall, Scott finds the book less helpful than expected for guiding clinical practice, but acknowledges its potential value in highlighting the importance of trauma screening and specialized trauma clinics.

Scott Alexander discusses a study challenging the idea that childhood abuse lowers IQ, and explores its implications for understanding the effects of child abuse on various outcomes. Longer summary

This post discusses a study by Danese et al. challenging the assumption that childhood abuse lowers IQ. The study found that after adjusting for pre-existing factors, there was no significant difference in IQ between abused and non-abused children. Scott Alexander explores the implications of this study in the context of shared-environment-skeptical psychiatry and discusses other studies showing limited effects of child abuse on various outcomes. He notes that while these findings are interesting, they may understate the dangers of severe abuse due to sample size limitations. The post concludes by suggesting that child abuse likely causes PTSD-like symptoms but may not have effects drastically different from normal PTSD. Shorter summary
