Understand the "become it" claim accurately
Sustained behavioral practice of confidence — acting as if — can build real self-efficacy over time, through mastery experiences rather than pose duration.
Why it works
Cuddy’s popular reformulation ("fake it till you become it") has a more defensible basis than the hormonal mechanism: behaving as a confident person behaves — making eye contact, volunteering, attempting difficult tasks — generates mastery experiences (Bandura) that update self-efficacy beliefs over time. The "becoming" comes from the behavior and its outcomes, not from two minutes of posture in a bathroom.
How to do it
- Identify one specific confident behavior you currently avoid (raising your hand, expressing an opinion, applying for a stretch role).
- Commit to doing it once this week, regardless of felt confidence — as if you already had the confidence.
- Debrief afterward: did the world end? What did you learn? What belief updated?
- Repeat with increasing stakes, tracking how your self-assessment of capacity shifts.
Evidence
Behavioral experiments that produce mastery experiences are among the best-supported mechanisms for building genuine self-efficacy; acting as-if generates the behavioral evidence that confident self-belief requires. (rct)
This mechanism takes time and requires genuine challenging behavior — it is not an instant fix. The original "fake it" framing implied a shortcut that the evidence does not support.

Common mistake
Interpreting "act as-if" as "perform confidence externally while feeling fraudulent internally," which produces imposter syndrome rather than genuine self-efficacy updating.

More practices for Power Posing Revisited
- Adopt expansive posture to shift subjective confidence
Upright, open posture — not a "power pose" — reliably correlates with higher self-reported confidence, even if the hormone claims did not hold.
- Create a pre-performance ritual that includes posture
A consistent pre-performance ritual — including posture — reduces anxiety and improves performance more reliably than any single element.
- Use value-based self-affirmation before threatening evaluations
Before a threatening evaluation, write for 10 minutes about a value that matters to you — unrelated to the domain being evaluated.
- Pair confidence work with honest, accurate appraisal of your actual standing
Confidence without accurate self-assessment is overconfidence — the goal is calibrated self-belief, not boosted belief.
- Use voice pacing and tone as accessible, real-time confidence levers
Speaking slowly, at moderate volume, with deliberate pauses signals confidence to listeners — and partially to yourself.
