I really appreciate the author's critical analysis of this correlation presented as "fact" by Radiolab and I love how Hacker News and other blogs take these types of scientific findings and dig in for the truth. I think the PNAS paper refutes the original conclusion pretty thoroughly - I wish the Nautilus author would just explain that.

I don't think we should dismiss effects just because they seem really large (as the Nautilus author claims) but I do think that it's incredibly irresponsible of Sapolsky and Radiolab to be uncritically citing a study that looks like it was debunked in 2011.

I also think it's strange that the author cites the SJDM paper which is much, much less convincing, claiming that it refutes the original experiment. It looks to me like that paper just shows that by simulating a non-random order of parole requests they can create data that looks like the original experiment.

I love that Hacker News posts these things and people go through and analyze the papers. No one outside of the specialized field could possibly have time to analyze all of these papers but they clearly have implications that matter for everyone. I wish that popular science shows would do a more thorough analysis of these results on their own.
