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:

Why Do DMT Users See Insects from a Parallel Universe?
The molecule DMT (N,N-Dimethyltryptamine) is a psychoactive chemical that causes intense visions and can induce its users to quickly enter a completely different "environment" that some have likened to an alien or parallel universe. The transition from our world to theirs occurs with no cessation of consciousness or…
