Amy Joy Casselberry Cuddy (born 1972)[1] is an American social psychologist. She became widely known for her 2012 TED talk, where she presented a 2010 study on "power posing" which she had co-authored. The TED talk, delivered at TEDGlobal 2012 in Edinburgh, Scotland, has been viewed more than 40 million times and ranks second among the most-viewed TED talks.[2][3] The results of the study have since been falsified,[4][5] and "power posing" became a prominent example of the replication crisis in the social sciences.[6] In December 2015 Cuddy published a self-help book advocating power posing. The lead author of the 2010 study, Dana Carney, in October 2016 released a statement recognizing the proposal's falsification,[7] while Cuddy as of September 2016 continued to advocate for it.[8]

Cuddy has also done work on stereotyping and discrimination, emotions, nonverbal behavior, and the effects of social stimuli on hormone levels.[4][9]


Cuddy grew up in a very small Pennsylvania Dutch town, Robesonia, Pennsylvania. She graduated from Conrad Weiser High School.[citation needed] She is a classically trained ballet dancer and worked as a roller-skating waitress when she was an undergraduate at the University of Colorado at Boulder.[citation needed]

When she was a sophomore in college she sustained a serious head injury in a car accident.[10][11] Her doctors told her she was not likely to fully recover and should anticipate significant challenges finishing her undergraduate degree. Her IQ fell temporarily by two standard deviations,[12][11]

In 1998, Cuddy earned a B.A. in Psychology, graduating magna cum laude, from the University of Colorado.[13] She attended the University of Massachusetts Amherst from 1998 to 2000 before transferring to Princeton University to follow her adviser, Susan Fiske.[4] She received a M.A. in 2003 and a Ph.D. in 2005 in Social Psychology (dissertation: “The BIAS Map: Behavior from intergroup affect and stereotypes”) from Princeton University.[13]

Cuddy was[year needed] an Assistant Professor of Psychology at Rutgers University, where she taught undergraduate social psychology.[citation needed] In 2012, Cuddy was an Assistant Professor at the Kellogg School of Management at Northwestern University,[14] where she taught leadership in organizations in the MBA program and research methods in the doctoral program

Cuddy was an Associate Professor of Business Administration at Harvard Business School, in the Negotiation, Organizations & Markets Unit.[year needed][dead link][15] At Harvard Business School, she taught MBA courses on negotiation, and power and influence, as well as executive education courses.[citation needed]

Cuddy married Paul Coster in August 2014 and has one son.[citation needed]



In 2002, Cuddy co-authored the proposal of the stereotype content model, with Susan Fiske and Peter Glick (Lawrence University), Cuddy developed [16] In 2007, the same authors proposed the "Behaviors from Intergroup Affect and Stereotypes" (BIAS) Map model.[17] These models propose to explain how individuals make judgments of other people and groups within two core trait dimensions, warmth and competence, and to discern how these judgments shape and motivate our social emotions, intentions, and behaviors.[18]

Power posing[edit]

Cuddy carried out an experiment with Dana Carney and Andy Yap[19] (Columbia University) on how nonverbal expressions of power (i.e., expansive, open, space-occupying postures)[20] affect people's feelings, behaviors, and hormone levels.[21] In particular, they claimed that adopting body postures associated with dominance and power ("power posing") for as little as two minutes can increase testosterone, decrease cortisol, increase appetite for risk, and cause better performance in job interviews. This was widely reported in popular media.[22][23][24] David Brooks summarized the findings, "If you act powerfully, you will begin to think powerfully."[11]

This and related research has been published in Journal of Personality and Social Psychology, Trends in Cognitive Sciences, Psychological Science, Research in Organizational Behavior, Advances in Experimental Social Psychology, and Science.

In 2014, Eva Ranehill and other researchers tried to replicate this experiment with a larger group of participants and a double-blind setup.[25] Ranehill et al. found that power posing increased subjective feelings of power, but did not affect hormones or actual risk tolerance. They published their results in Psychological Science.[26]

Carney, Cuddy, & Yap responded in the same issue of Psychological Science,[27] with an overview of 33 published studies related to power posing, including the Ranehill et al. study. Almost all had reported significant effects of some kind. The overview noted methodological differences between their 2010 study[19] and the Ranehill replication, which may have moderated the effects of posing.[28]

Two researchers at the Wharton School, Simmons & Simonsohn, later shared a meta-analysis of the same 33 studies on their statistics blog.[29] Based on the distribution of p-values reported across the studies (the 'p-curve'), they concluded that studies so far have demonstrated little to no average effect of power posing.[30] Their analyses will appear in Psychological Science.[31]

In a pre-registered direct replication, Garrison et al.[32] found that expansive (vs. contractive) body postures had either no effect or actually reduced psychological states associated with power. The fact the study was pre-registered, had a large n (over 300), used multiple measures of power (an ultimatum game, a gamble, and feelings of being powerful and in charge), and tested not only posing but adopting a direct eye gaze increases confidence that expansive poses have no or in fact negative effects on feelings of power.

Another critique of the findings and methodology appeared in a January 2016 article published in Slate magazine by two professors at Columbia University.[33]

In response to the results of these replication studies and meta-analysis, one of the co-authors of the 2010 paper, Carney, has repudiated this line of research in an open letter dated September 2016, stating "The evidence against the existence of power poses is undeniable", and discouraging others from studying power poses. Reflecting on what may have been flawed about their 2010 paper, Carney admits that their methodology included some instances of p-hacking, such as discarding certain variables of "self-reported confidence" that did not correlate with making power poses.[34] The other two authors, Cuddy and Yap, have not repudiated their initial results.

Since the release of Carney's statement a special issue of Comprehensive Results in Social Psychology has been published on the topic of power posing. A summary paper co-authored by Carney entitled "CRSP special issue on power poses: what was the point and what did we learn?", states that a meta-analysis of the preregistered studies included in the issue, "showed a reliable non-zero effect on felt power".[35] In fact, according to Gronau et al, who conducted this meta-analysis, it "yields very strong evidence for an effect of power posing on felt power".[36]

The "power posing" theory has been described as an example of the replication crisis in psychology, in which initially seductive theories can not be replicated in follow-up experiments.[6]



In December 2015 Cuddy published a self-help book advocationg power posing, Presence: Bringing Your Boldest Self to Your Biggest Challenges, which built on the value of the outward practice of power posing to focus on projecting one's authentic self with the inward-focused concept of presence—defined as “believing in and trusting yourself – your real honest feelings, values and abilities.”[37] The book reached at least as high as #3 on The New York Times Best Seller list (Advice, How-To & Miscellaneous) in February 2016.[38] The book was translated into German in 2016.[39]
