stapel_npcIt turns out we missed two more recent retractions from Diederik Stapel. They were nestled in the table of contents of the Journal of Personality and Social Psychology that contained four retractions we covered last week.

The notices, for “Method matters: Effects of explicit versus implicit social comparisons on activation, behavior, and self views” (cited 48 times, according to Thomson Scientific’s Web of Knowledge) and “From seeing to being: Subliminal social comparisons affect implicit and explicit self-evaluations” (cited 95 times), both say the same thing: Read the rest of this entry »
