Using P-Curve to Assess Evidentiary Value of Social Psychology Publications

© ImagesRouges –

The proposed project will utilize p-curve, a new meta-analytic tool to assess the evidentiary value of studies from social psychology and behavioral marketing. P-curves differs from meta-analytic methods by analyzing the distribution of p-values to determine the likelihood that a study provides evidence for the existence of an effect; in the event that there is not evidentiary value in a study, p-curve can also determine whether a study is powered such that it would detect an effect 33% of the time, given it exists. We will apply p-curve to each empirical paper in the first issue of 2014 in three top-tier journals: Psychological Science, The Journal of Personality and Social Psychology, and The Journal of Consumer Research. Additionally, we will conduct a direct replication of one study from each of these issues.
