Retraction Watch on Förster (Blog)

Retractionwatch has two pieces out on alleged data irregularities in work published by social psychologist Jens Förster. They cite an unnamed (!) (LOWI?, UvA?) report dated 2012: These papers report 40 experiments involving a total of 2284 participants (2242 of which were undergraduates). We apply an F test based on descriptive statistics to test for linearity of means across three levels of the experimental design. Results show that in the vast majority of the 42 independent samples so analyzed, means are unusually close to a linear trend.
