Power posing significantly increases confidence and success.
NOT BSTOTAL BS
MOSTLY BS — Verdict: Mostly False
Verified by Lenz ·
The Short Version
The best available evidence — including large pre-registered studies and meta-analyses — shows power posing produces a real but small effect on subjective feelings of power. It does not reliably change hormones, and behavioral or cognitive outcomes that would constitute "success" are weak or absent. The claim's use of "significantly" overstates the effect size, and pairing "confidence" with "success" implies downstream real-world benefits that the evidence does not support. The original 2010 findings have been substantially undermined by replication failures.
Caveats
The word 'significantly' conflates statistical significance (a technical threshold) with practical significance (a meaningful real-world impact) — the actual effect on subjective confidence is small.
No reliable evidence supports that power posing leads to measurable 'success' outcomes such as improved performance, decision-making, or risk-taking behavior.
The original 2010 hormonal and behavioral claims that popularized power posing have not been replicated and are considered unsupported by current meta-analyses.
