Résumé de Presence

In "Presence," social psychologist Amy Cuddy argues that people can summon confidence in high-stakes moments not by waiting to feel powerful but by first adjusting their body language. Expanding on her widely discussed TED talk about "power posing," Cuddy describes how adopting expansive, open postures—rather than contracted, protective ones—can shift how someone feels and is perceived. She frames presence as "the state of being attuned to and able to comfortably express our true thoughts, feelings, values, and potential," a quality that emerges when we stop worrying about how others judge us. The book blends personal narrative with experimental psychology. Cuddy recounts her own recovery from a traumatic brain injury after a car accident in college, which doctors said would prevent her from finishing her degree; she describes how faking competence and persistence helped her rebuild an identity she feared was lost. This experience anchors her central concept of "self-nudging"—using small tweaks to body and mind, rather than grand transformations. She also introduces "power posing" research showing that holding expansive poses for a couple of minutes can raise testosterone and lower cortisol, though this finding later drew scholarly criticism and failed replications, which Cuddy addresses. Other chapters explore impostor syndrome, particularly among high-achieving women, and the idea that confidence often follows action rather than preceding it. Cuddy stresses that presence is not about dominating a room but about listening, being authentic, and trusting oneself under pressure. Widely reported premises include her advice to "fake it till you become it" and her claim that the body shapes the mind. The book reached bestseller lists and remains a prominent, if contested, entry in the communication and self-presentation genre.
