In June 2012, Amy Cuddy, a professor at Harvard Business School, took the Internet by storm with a TED talk on a radical new way to prepare for job interviews. She recommended a technique dubbed “power-posing”: taking on a powerful stance, as in standing arms akimbo. Cuddy’s research claimed that just two minutes of power-posing could alter hormone levels in the blood. She and her team reported that power-posing increased testosterone and decreased cortisol, with the net result that people felt more confident. The power posers in the study were deemed better job candidates than the non-posers. In short, people who felt more powerful were more likely to land the job.
