May 24, 2025

Lecture Notes: Amy Cuddy on Body Language and Power Posing

Introduction

  • Speaker: Amy Cuddy
  • Main Idea: The impact of body language on self-perception and interpersonal interactions.
  • Life Hack: Changing one's posture for just two minutes can have significant effects on life outcomes.

Body Language and Nonverbals

  • Importance of body language in communication.
  • Nonverbal signals influence how we judge others and how others judge us.
  • Body language can affect important decisions:
    • Hiring and promotions
    • Dating decisions
  • Research Examples:
    • Nalini Ambady's study: Physician's niceness predicts lawsuits based on 30-second clips.
    • Alex Todorov's study: Judgments of political candidates' faces predict election outcomes.

Power Dynamics of Body Language

  • Nonverbal expressions of power: Expanding oneself (taking up space) vs. closing oneself (making oneself small).
  • Animal Kingdom Comparison: Both animals and humans exhibit similar power expressions.
  • Pride expressions are universal: Both sighted and blind individuals exhibit the same physical behaviors when they win.

Observations in Classroom Settings

  • MBA students demonstrate a wide range of power nonverbals:
    • Alphas occupying space vs. students making themselves small.
  • Gender differences observed in power expression.
  • Participation in class linked to power dynamics observed in students.

Research on Power Posing

  • Key Questions:
    1. Can "fake it till you make it" work for power expressions?
    2. Do our nonverbals change how we think and feel about ourselves?
  • Evidence shows:
    • Smiling can induce happiness, and adopting powerful poses can influence feelings of power.
    • High-power poses lead to hormonal changes: Increase in testosterone and decrease in cortisol.

Experiment on Power Posing

  • Participants took high or low-power poses for two minutes.
  • Findings:
    • 86% of high-power posers took risks (gambling) vs. 60% of low-power posers.
    • Hormonal changes observed:
      • High-power posers: 20% increase in testosterone, 25% decrease in cortisol.
      • Low-power posers: 10% decrease in testosterone, 15% increase in cortisol.

Application of Findings

  • Power posing recommended for evaluative situations (e.g., job interviews).
  • Caveat: Do not perform poses in front of others; do them privately to influence self-perception before evaluations.

Real-Life Implications

  • Cuddy shares a personal story of overcoming feelings of impostor syndrome through power posing.
  • Encouragement to others who feel out of place to embrace power posing.
  • Key Message: "Fake it till you become it."
  • Small changes in body posture can lead to significant changes in perception and outcomes.

Conclusion

  • Takeaway: Tiny tweaks (like posture changes) can lead to big changes in life.
  • Encourage sharing this knowledge with others, particularly those who lack resources, as it can empower them.
