In 2010, a group of researchers published the finding that power posing—adopting a wide stance with one’s hands on one’s hips—improved self-reported feelings of power and increased testosterone levels in a sample of 42 participants (Carney, Cuddy, & Yap, 2010). Subsequent attempts to replicate the original study have yielded mixed results (Simmons & Simonsohn, 2017). Although some studies found the same effect, others found no effects of power posing, including one study that tested 200 participants (Ranehill et al., 2015). Sometimes there are good reasons that studies are not able to replicate previously published results, but sometimes this failure occurs because the original researchers engaged in unethical research practices. Use the concept of p-hacking to describe some potential reasons that there may be mixed results for the effects of power posing.
