Deriving the piano keyboard from biological principles using clustering
Once upon a time we were creatures in the wilderness and we evolved the ability to hear sounds. Now here's an interesting thing, if you hear a sound of frequency f and others of frequency 2f, 3f, etc then there's a good chance these sounds come from the same object, due to the physical principle of resonance .

Noted study in psychology fails to replicate, crumbles with evidence of fraud
About 80 people pointed me to this post by Uri Simonsohn, Joe Simmons, and Leif Nelson about a 2012 article, “Signing at the beginning makes ethics salient and decreases dishonest self-reports in comparison to signing at the end.” Apparently some of the data in that paper were faked; see for example here:
