Power Posing
The hypothesis, popularized by Amy Cuddy, that adopting expansive 'high-power' body postures briefly influences hormones, feelings of power, and behavior — a contested claim with mixed replication evidence.

Explanation
Power posing refers to the deliberate use of expansive, open-bodied postures — feet apart, hands on hips, arms raised in a 'V', leaning back with arms behind the head — to influence one's psychological and physiological state. The idea was popularized by social psychologist Amy Cuddy in a 2010 paper (Carney, Cuddy & Yap) and a widely viewed TED talk.
Original claims:
- Two minutes of high-power posing increased testosterone and decreased cortisol.
- It increased subjective feelings of power and willingness to take risks.
- It improved performance in evaluative settings like job interviews.
The replication story:
- The hormonal claims have largely failed to replicate. Carney herself later stated she no longer believes in the hormonal effects.
- The behavioral risk-taking findings have also failed to replicate robustly.
- The most consistent surviving finding is on **felt sense of power** — adopting expansive postures reliably makes people *feel* more powerful, even if downstream behavioral and hormonal effects are smaller or absent.
- Cuddy has since framed the more modest claim — about subjective experience — as the defensible core of the work.
Why include it as a concept:
- Power posing is a textbook case of how an [[embodied-cognition]] claim was overstated, popularized, and then trimmed back through replication.
- It remains relevant as a sibling to [[enclothed-cognition]], [[alter-ego-effect]], and [[batman-effect]] — all leverage the body and presentation to influence cognition.
- The narrower 'felt power' effect is still useful: changing posture before a high-stakes moment is a cheap intervention with at least a subjective payoff.
Lessons for the discerning reader: prefer small claims that survive replication over big claims that go viral, and treat power posing as an example of how to evaluate psychology findings as they evolve.
