Fake It ’til You Make It – The Power Pose Parable Part II

Where does p-hacking and the replication crisis leave the state of scientific studies?

Last time, we explored the findings of a 2010 psychological study, which concluded that assuming a “power pose” for two minutes increases testosterone (confidence) and decreases cortisol (stress). But it turned out that p-hacking affected the results of the initial study, and that subsequent studies debunked the “power pose” findings.

Saliva samples were used to measure the dominance hormone testosterone and the stress hormone cortisol. Risk-taking was gauged by a willingness to take a bet with a 50 percent chance of winning $2 and a 50 percent chance of losing…
