A Negative Effect of a Contractive Pose is not Evidence for the Positive Effect of an Expansive Pose: Comment on Cuddy, Schultz, and Fosse (2018)

Cuddy, Schultz and Fosse (2018) present the results of p-curve analyses that are interpreted as providing "clear evidential value for power posing effects”. This commentary highlights that the vast majority of the studies included in the p-curve analyses were not designed in a way that could speak to the efficacy of power poses relative to a normal or neutral pose. Further, I discuss how the few studies that were designed to shed light on this issue indicate that any overall effect of physical pose on feelings of power, emotions, affect, and self-evaluations is almost entirely due to the negative effect of a contractive pose and not any positive effect of expansive power poses.
