Scott Alexander critiques a New York Times article claiming psychology is not in crisis despite low replication rates. He argues that the article ignores publication bias, experimenter effects, and low base rates of true hypotheses. Scott contends that even if failed replications are due to different conditions, this still represents a crisis as it undermines the practical utility of psychological findings. He suggests that while we can't investigate every failed replication, studying some might reveal why replication issues keep occurring in psychology. Shorter summary

Scott Alexander critiques a meta-analysis supporting psychic phenomena to illustrate flaws in scientific methodology and meta-analysis. Longer summary

He uses this to illustrate broader issues with the scientific method and meta-analysis, concluding that even seemingly rigorous studies and meta-analyses can produce incorrect conclusions. This challenges the idea that scientific consensus and meta-analysis are the highest forms of evidence. Shorter summary
