Scott Alexander dissects a hoax chocolate study to critique common misconceptions about nutrition science, study design, and statistical methods. Longer summary

Scott Alexander analyzes a viral study claiming chocolate aids weight loss, which was revealed as a hoax designed to expose poor science journalism. He critiques four common but incorrect conclusions drawn from this incident: that people were gullible for believing it, that nutrition isn't a real science, that studies always need high sample sizes, and that p-values should be eliminated. Scott argues that there is previous research supporting chocolate's health benefits, that nutrition science uses multiple study types to build evidence, that sample size importance depends on the effect being studied, and that p-values have their place in research. He agrees with the fifth conclusion that science journalism should be trusted less, but notes that some sources like Wikipedia and specialized blogs are more reliable. Shorter summary

Scott Alexander defends psychiatry's use of 'chemical imbalance' theory, arguing it was meant to emphasize depression's biological basis rather than claiming a simple serotonin deficiency. Longer summary

Scott Alexander responds to criticisms of psychiatry's use of the 'chemical imbalance' theory of depression. He argues that psychiatrists never claimed depression was simply a serotonin deficiency, but rather a complex interaction of brain chemicals. He explains that the term 'chemical imbalance' was used to emphasize depression's biological basis and help people take it seriously, rather than viewing it as a personal failure. Scott provides evidence that serotonin and other neurotransmitters are indeed involved in depression, while acknowledging the full picture is more complicated. He concludes that framing depression in terms of brain chemistry remains useful, even if 'chemical imbalance' is no longer the best terminology. Shorter summary
