Scott argues that AI companies' existential-risk warnings are sincere rather than a corporate plot, since independent experts share them, leaders voiced them long before founding companies, and the supposed plot would be self-defeating.

A replication of a 2023 neuroscience study on brain entrainment and learning found that the original effect likely doesn't exist, revealing how the study obscured key issues through statistical averaging and highlighting how AI tools are democratizing scientific scrutiny.

Scott examines whether reported increases in "crime" actually reflect concerns about "disorder" (litter, graffiti, shoplifting, homelessness, tent encampments), finding that most disorder metrics are either stable or down from historical highs, contradicting narratives of societal collapse.

Scott examines why young people feel economically hopeless despite economists saying things are fine, testing various explanations like housing costs and wages, and concluding the truth involves both real factors (harder competition, expensive cities, recent mortgage spikes) and media-driven negativity.

A detailed insider look at Phase I clinical drug trials, revealing how the system's structure encourages participants to routinely lie about their medical history and symptoms to continue participating.

Scott investigates AI psychosis through historical analogies and a reader survey, finding it affects roughly 1 in 10,000 to 100,000 people yearly, with most cases involving pre-existing risk factors.

Scott Alexander explores correlations between PMS symptoms and various beliefs and traits, finding significant connections that leave him puzzled.

Scott Alexander investigates the optimal dosage of Lexapro, comparing it to other antidepressants and exploring the reasons behind its effectiveness at lower doses.

Scott examines the relationship between sleep, synaptic homeostasis, and depression, exploring how sleep deprivation temporarily alleviates depression symptoms.

Scott Alexander conducts a personal randomized controlled trial of a sleep supplement, finding no significant effect over placebo, but gains insights into his sleep patterns.

Scott Alexander analyzes birth order effects in SSC readers, finding strong effects for sibling age gaps of 1-7 years, with a significant drop-off after 7 years.

Scott Alexander outlines 18 preregistered investigations for the 2019 SSC survey, covering topics from psychiatric medication effects to birth order influences.

Scott Alexander revisits his stance on SSRIs, discussing new meta-analyses, broader trends in psychiatric medication efficacy, and potential explanations for the discrepancy between statistical and clinical observations.

Scott Alexander recounts his frustrating attempt to conduct a study on a bipolar disorder screening test, highlighting the excessive bureaucratic hurdles that ultimately led to the study's abandonment.

A collection of interesting links covering science, politics, economics, and culture, with Scott's commentary on each story.

Scott Alexander presents a roundup of recent medical and psychological studies, covering topics from UV light exposure to belief in science during stress.

Scott highlights a study showing juries give harsher penalties for crimes affecting few people versus many, demonstrating the cognitive bias of scope insensitivity.

Scott examines the universal human bias toward supporting underdogs, presents evidence it significantly influences opinions, and asks why evolution would favor such an apparently irrational strategy.

Scott explains two psychological techniques for detecting hidden attitudes: the Bogus Pipeline (a fake lie detector that reduces conscious lying) and the Bona Fide Pipeline (a reaction-time computer test that measures unconscious associations).

Scott surveys research on priming, including studies showing it can sway political judgments and votes, and suggests deciding important matters in a neutral environment.

Scott explains Ramachandran's theory that anosognosia and split-brain confabulation reflect a left-brain 'apologist' and a right-brain 'revolutionary' whose balance governs our ability to change our minds.

Scott uses Calvinist predestination and Tversky's ice-water heart study to show how people confuse correlation with causation and deceive themselves about their own motives.

Scott uses self-handicapping studies to argue that people can hold a biased belief on the surface and an accurate one underneath, much like belief in belief.
