Skip the hormonal "power pose" promises

Use posture for felt confidence, but don’t believe it’s changing your hormones.

Why it works

The original power-posing claim was that two minutes of expansive poses raised testosterone, lowered cortisol, and increased risk-taking. The honest mechanism is much narrower: any benefit comes from self-perception and felt confidence (embodied cognition), not endocrine change. Knowing this keeps you from leaning on an effect that isn’t real and lets you use the part that is.

How to do it

1. If an expansive stance helps you feel ready before a high-stakes moment, use it — for the felt effect.
2. Don’t count on it to change your hormones or make you take bigger risks.
3. Pair it with substance — preparation and rehearsal — rather than treating the pose as the work.

Evidence

The original power-posing hormonal and risk-taking effects largely failed to replicate in a larger, pre-registered study; later work supports only a modest "felt power" / self-report effect. (mechanistic)

Even one of the original authors later distanced herself from the hormonal claims while maintaining the felt-confidence effect may exist. Treat strong physiological claims as unsupported.

Common mistake

Believing a two-minute pose will physiologically transform you, then feeling cheated when it doesn’t — the honest, smaller felt-confidence effect is the part to actually use.
