Researchers around Amy Cuddy of Harvard Business School concluded in a study in 2010 that power poses held for a short time influenced the hormones and the willingness to take on financial risks for the subjects participating in the study. Scientists of the University of Zurich now refute these findings with a large study
“This indicates that the main influence of power poses is the fact that subjects realize that the feel more self-confident. We find no proof, however, that this has any effect on their behavior or their physiology.”
“Our study is much more meaningful than the original study, as we have much more data…The greater number of subjects in our study makes it much less probable that our results are due to coincidence. Our study is to the best of our knowledge the only published paper that again examines the effect of power poses on hormones.” Roberto Weber adds that the results of the new, larger study also demonstrate how important it is to replicate published research results.
