Amy Cuddy introduces a "no-tech life hack" involving changing body posture for two minutes. She asks the audience to audit their current posture, highlighting how many people make themselves smaller (hunching, crossing legs) or spread out. She emphasizes that this simple change can significantly alter one's life.
Cuddy discusses the fascination with body language and how it influences our judgments of others. She provides examples like the significance of a handshake and how nonverbal cues can predict meaningful life outcomes, such as hiring decisions, dating prospects, and even the likelihood of a physician being sued or a political candidate winning an election. She also notes that our nonverbals influence how we perceive ourselves.
Cuddy, as a social psychologist, explains her interest in power dynamics and the nonverbal expressions associated with power and dominance. She illustrates how both animals and humans, when powerful, expand their bodies to take up space, citing the universal expression of pride. Conversely, when feeling powerless, individuals tend to close up and make themselves small. She observes these behaviors in her MBA classroom, noting a gender disparity in power posing and its correlation with class participation and grades.
Cuddy and her collaborator Dana Carney investigated whether adopting powerful poses could lead to actual behavioral outcomes and changes in self-perception. They hypothesized that just as our minds change our bodies, our bodies might change our minds. She explains how feelings of power correlate with increased assertiveness, confidence, and optimism, and how physiological markers like testosterone (dominance hormone) and cortisol (stress hormone) differ between powerful and powerless individuals.
The experiment involved participants adopting high-power or low-power poses for two minutes. The results showed that those in high-power poses had an 86% likelihood of gambling (indicating higher risk tolerance), a 20% increase in testosterone, and a 25% decrease in cortisol. In contrast, those in low-power poses showed a decrease in testosterone and an increase in cortisol. These findings suggest that two minutes of power posing can configure the brain to be more assertive and less stress-reactive.
Cuddy emphasizes applying power posing in evaluative and socially threatening situations, such as job interviews, public speaking, or school board meetings. She clarifies that power posing is not about performing for others in the interview itself, but rather about preparing oneself beforehand. She suggests finding two minutes before such situations to power pose privately, like in a bathroom, to configure one's brain for optimal performance.
Cuddy addresses the common concern that power posing feels "fake." She shares her personal story of overcoming impostor syndrome after a severe car accident lowered her IQ, and how she was encouraged by her advisor to "fake it till you make it." This led to her realization that it's not about faking it until you achieve an external goal, but faking it until you internalize the feeling and "become it." She recounts an interaction with a struggling student who also felt like an impostor, demonstrating that this simple advice transformed the student's confidence and performance. Cuddy urges the audience to embrace "fake it till you become it" to truly change oneself from within.
Cuddy concludes by reiterating that tiny tweaks can lead to big changes. She encourages everyone to practice power posing for two minutes before stressful situations to elevate testosterone and lower cortisol, allowing them to express their true selves rather than feeling shut down. She also calls for sharing this simple, accessible science with others, especially those who lack resources, technology, or status, as it only requires one's body, privacy, and two minutes to potentially change the course of their lives significantly.
