Scott Alexander analyzes online drug ratings, finding patients prefer older antidepressants while doctors prefer newer ones, and explores potential explanations for this paradox.
Longer summary
Scott Alexander analyzes patient ratings of antidepressants from online databases, finding that older drugs like MAOIs are rated higher than newer ones. He then compares this to doctor ratings, discovering a negative correlation between patient and doctor preferences. The post explores possible explanations for these paradoxical results, including confounding factors and the hypothesis that newer antidepressants may actually be less effective. Scott extends the analysis to other drug classes, finding the negative doctor-patient correlation holds broadly, while the preference for older drugs is specific to psychiatric medications.
