Replication Data for “Power Posing: Brief Nonverbal Displays Affect Neuroendocrine Levels and Risk Tolerance” by Carney, Cuddy, Yap (2010)

This analysis replicates the main experimental results in “Power Posing: Brief Nonverbal Displays Affect Neuroendocrine Levels and Risk Tolerance” by Carney, Cuddy, and Yapp (2010). The main experiment assessed the effects of power posing (high vs. low) on participants' testosterone and cortisol levels, feelings of power, and risk-taking behavior. The replication analysis provides code, data, and results that: (1) replicate composite scores and create an improved replication data set for re-analysis; (2) provide summary statistics on the full sample of participants; (3) replicates every main statistical finding using the main experimental data; (4) identifies several reporting and coding errors in the original study; (5) evaluates the consequences of these errors in robustness re-analyses. It was found that re-analyses that correct for these errors, following the intended analytic decisions by the study authors, do not substantially alter the interpretation of the study's main experimental results.
