Power posing is a controversial self-improvement technique or "life hack" in which people stand in a posture that they mentally associate with being powerful, in the hope of feeling more confident and behaving more assertively. Though the underlying science is disputed, its promoters continue to argue that people can foster positive life changes simply by assuming a "powerful" or "expansive" posture for a few minutes before an interaction in which confidence is needed. One popular image of the technique in practice is that of candidates "lock[ing] themselves in bathroom stalls before job interviews to make victory V's with their arms." [1]
Power posing was first suggested in a 2010 paper by Dana R. Carney, Amy Cuddy, and Andy Yap in the journal Psychological Science , [2] and came to prominence through a popular TED talk by Cuddy in 2012. [3] However, in 2015 several researchers began reporting that the effect could not be replicated, [4] [5] [6] and, in 2016, Carney issued a statement abandoning the theory. [7] Cuddy, however, continued her research, [8] [1] claiming to have evidence that posture feedback can at least make people feel more powerful. [9] [10] [11] Today, power posing is often cited as an example of the replication crisis in the sciences. [12]
The initial research on power posing was published in 2010. Dana Carney, Amy Cuddy, and Andy Yap claimed that high-power poses "produce power". The study included 42 participants, who were coached by researchers to assume a physical position of power. Hormone levels were measured before and after, and the authors stated that they found an increase in testosterone and a decrease in cortisol after posing. [1] The researchers themselves suggested a range of possible real-world applications:
These findings suggest that, in some situations requiring power, people have the ability to "fake it 'til they make it." Over time and in aggregate, these minimal postural changes and their outcomes potentially could improve a person's general health and well-being. This potential benefit is particularly important when considering people who are or who feel chronically powerless because of lack of resources, low hierarchical rank in an organization, or membership in a low-power social group." [2]
The researchers concluded that power posing induces lasting hormonal changes, which can lead to better outcomes in work-related situations, such as job interviews and wage negotiations.
The earliest criticism of Carney, Cuddy and Yap's work came from Steven Stanton, who noted their lack of attention to gender differences. "Carney et al. used a novel manipulation to ask an important question," he concluded, "but the degree to which their findings can be fully understood and implemented into future research is questionable without more complete analyses." [13]
A 2015 article, published in Psychological Science by Ranehill et al. reported the results of a conceptual replication of the study using a larger sample. The researchers confirmed Carney et al.'s results about felt power but could not detect any physiological or behavioral effects of power posing. [4] The statistical methods that may have led to the original erroneous findings were reviewed by Uri Simonsohn and Joseph Simmons of the Wharton School in a 2016 paper, concluding that the current body of research fails to "suggest the existence of an effect once we account for selective reporting". [5] [14] [15]
In the years that followed, attempts were made by various research groups to apply power posing manipulation in different contexts. The results did not support the assumptions made by Cuddy et al. In a 2016 study by Garrison et al. the effect of posture manipulation was combined with dominant vs. submissive gaze. However, no effect was found on risk taking and, in contrast to original expectations, adopting an expansive pose reduced feelings of power. [16] Deuter et al. (2016) investigated the effect of cognitive role taking and Cuddy's power posing manipulation in the Trier Social Stress Test; although role taking had an influence on the cortisol and testosterone response after stress, the posture manipulation had no effect on hormonal, behavioral or subjective measures. [17]
In a study conducted by Smith et al. in 2017, participants had to compete in a challenging task while they had to assume high or low power poses. The authors report no main effect of pose type on testosterone, cortisol, risk or feelings of power. However, they found an interaction between pose type and competition outcome on testosterone: while winners assigned to a high-power pose had small increases in testosterone levels, losers had a reduction in testosterone after holding high-power poses. [18]
In 2016, Dana Carney, who had been the lead author on the original 2010 paper and had supported the publication of the 2015 Ranehill et al. replication attempt, published a statement on the University of California, Berkeley website, stating that she no longer believed the effect was valid: "I do not believe that 'power pose effects' are real...the evidence against the existence of power poses is undeniable." [1] [7] [19] [8]
Joseph Cesario, an associate professor of psychology at Michigan State University, who co-edits Comprehensive Results in Social Psychology, arranged a special issue on power posing that published in June 2017; the issue included eleven new studies, along with a meta-analyses, which found that the effect of power posing on power behaviors was not replicated. [5] [20] [21] [22] [23] The published studies were designed to answer whether the power-posing hypothesis was real and included high quality research features like pre-registration of endpoints. [24] Carney co-authored the introduction to the issue, and noted that while the meta-analysis failed to find any effect in power behaviors, it did find a medium-sized effect in a feeling of power; she also wrote that the studies could not resolve whether the effect on a feeling of power was only an experimental artifact. [24]
In 2017, a meta-study by Cuddy et.al, surveyed 55 studies about power poses, and found "strong evidential value for postural-feedback (i.e., power-posing) effects and particularly robust evidential value for effects on emotional and affective states (e.g., mood and evaluations, attitudes, and feelings about the self)" [25]
A comprehensive meta-analytic review that analyzed 128 studies on the topic of body postures such as power posing, considering both published and unpublished papers, suggests that power posing has a reliable effect on thoughts and feelings (e.g., positive mood, self-esteem, feelings of dominance). However, power posing has no effect on physiological measures (e.g., hormone levels, blood pressure, skin conductance). Although the authors report an effect on behavioral measures, it remains unclear whether this effect actually exists or is due to selective reporting of significant results. In addition, the researchers point to limitations of the power posing literature: Few studies have included a control group (neutral posture), so it remains unclear whether the effect comes from dominant postures (so-called high power poses) or from submissive, slumped postures (so-called low power poses). [26]

Several researchers noted the lack of control groups in many power posing studies. Many studies had only compared power poses to contractive poses like slouching but had failed to include a normal pose as a control group. [27] [26]
The problem falls under a general problem called the "poison-medicine" problem; [28] comparing a medicine (m) to a poison (p) would not establish if the medicine works in promoting longevity (y) if a baseline (neutral, i.e. placebo) condition is not included because if y(m) > y(p) this difference could arise for a multitude of reasons including that (a) m does not work and p reduces y, or (b) m reduced y but p reduces y more. That a difference is observed in y(m) and y(p) does not necessarily mean that it was caused by the expected treatment effect. This issue is often overlooked in testing some psychology theories wherein incorrect comparisons have been made (e.g., in Galinsky-type power priming studies, where a high and low power prime are often compared; [28] when a baseline is included, priming of this sort creates an asymmetric demand effect, which precludes making correct causal inference). [29] [30]
Since its promotion in a 2010 Harvard Business School Working Knowledge post, [31] Amy Cuddy has been the most visible proponent of power posing in the public sphere. Her interest in "studying how people can become their aspirational selves" stems from her own experience of recovering from head trauma after a car accident. [1] The power posing "hack" gained wide attention after a TED talk she gave in 2012, where she demonstrated the posture and argued for its benefits. [3] The technique was then covered by CNN and Oprah Winfrey; it was the centerpiece of her 2015 book Presence: Bringing your boldest self to your biggest challenges; and by 2017 her TED talk had been viewed by about 47 million viewers, becoming the second most popular. [1]
In 2015, several news outlets in the United Kingdom said that some members of the UK Conservative Party had begun to adopt a "bizarre" wide stance at high-profile political events, which some suggested was based on Cuddy's 'power posing' advice. [32] [33] [34] [35] [36] [37] While this was referred to by some as the "Tory power pose", [38] [39] it had previously been used by Labour Prime Minister Tony Blair. [40] [41] [39] Politicians publicly photographed in this stance include Sajid Javid, George Osborne, David Cameron, [42] Tony Blair, [43] and Theresa May. [44] [43]
By 2016, public discussion of power posing had shifted to the difficulty of replicating the effect in subsequent studies. An extensive series of articles on power posing replication was published by New York magazine by Jesse Singal and other contributors in its Science of Us section. [8] [19] [45] [46] There was intense controversy around these issues and Cuddy reported experiencing harassment, including death threats, after the findings were not replicated. [47] In the spring of 2017, Cuddy left Harvard but continues to promote power posing as life-improvement technique. [1] [10]
In psychology, libido is psychic drive or energy, usually conceived of as sexual in nature, but sometimes conceived of as including other forms of desire. The term libido was originally developed by Sigmund Freud, the pioneering originator of psychoanalysis. With direct reference to Plato's Eros, the term initially referred only to specific sexual desire, later expanded to the concept of a universal psychic energy that drives all instincts and whose great reservoir is the id. The libido - in its abstract core differentiated partly according to its synthesising, partly to its analytical aspect called life- and death-drive - thus becomes the source of all natural forms of expression: the behaviour of sexuality as well as striving for social commitment, skin pleasure, food, knowledge and victory in the areas of species- and self-preservation.
Estrogen is a category of sex hormone responsible for the development and regulation of the female reproductive system and secondary sex characteristics. There are three major endogenous estrogens that have estrogenic hormonal activity: estrone (E1), estradiol (E2), and estriol (E3). Estradiol, an estrane, is the most potent and prevalent. Another estrogen called estetrol (E4) is produced only during pregnancy.
Testosterone is the primary male sex hormone and androgen in males. In humans, testosterone plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. It is associated with increased aggression, sex drive, dominance, courtship display, and a wide range of behavioral characteristics. In addition, testosterone in both sexes is involved in health and well-being, where it has a significant effect on overall mood, cognition, social and sexual behavior, metabolism and energy output, the cardiovascular system, and in the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty, accumulation of adipose fat tissue within the body, anxiety and depression, sexual performance issues, and bone loss.
The relationship between biology and sexual orientation is a subject of on-going research. While scientists do not know the exact cause of sexual orientation, they theorize that it is caused by a complex interplay of genetic, hormonal, and environmental influences. However, evidence is weak for hypotheses that the post-natal social environment impacts sexual orientation, especially for males.
An aphrodisiac is a substance alleged to increase libido, sexual desire, sexual attraction, sexual pleasure, or sexual behavior. These substances range from a variety of plants, spices, and foods to synthetic chemicals. Natural aphrodisiacs, such as cannabis or cocaine, are classified into plant-based and non-plant-based substances. Synthetic aphrodisiacs include MDMA and methamphetamine. Aphrodisiacs can be classified by their type of effects. Aphrodisiacs that contain hallucinogenic properties, such as bufotenin, have psychological effects that can increase sexual desire and sexual pleasure. Aphrodisiacs that have smooth muscle relaxing properties, such as yohimbine, have physiological effects that can affect hormone concentrations and increase blood flow.
The digit ratio is the ratio taken of the lengths of different digits or fingers on a hand.
An anaphrodisiac is a substance that quells or blunts the libido. It is the opposite of an aphrodisiac, something that enhances sexual appetite. The word anaphrodisiac comes from the Greek privative prefix ἀν-, denoting negation, and aphrodisiac, from the Greek goddess of love, Aphrodite. Some people use anaphrodisiacs in order to curb a very high libido or due to hypersexuality. However anaphrodisiacs are also used by those with an average libido, at times due to having incessant schedules.
Testosterone cypionate, sold under the brand name Depo-Testosterone among others, is an androgen and anabolic steroid (AAS) medication which is used mainly in the treatment of low testosterone levels in men, including hormone therapy for transgender men. It is given by injection into muscle or subcutaneously, once every one to four weeks, depending on clinical indication.
Feminizing hormone therapy, also known as transfeminine hormone therapy, is hormone therapy and sex reassignment therapy to change the secondary sex characteristics of transgender people from masculine or androgynous to feminine. It is a common type of transgender hormone therapy and is used to treat transgender women and non-binary transfeminine individuals. Some, in particular intersex people, but also some non-transgender people, take this form of therapy according to their personal needs and preferences.
The relationship between the environment and sexual orientation is a subject of research. In the study of sexual orientation, some researchers distinguish environmental influences from hormonal influences, while other researchers include biological influences such as prenatal hormones as part of environmental influences.
Alcohol and sex deals with the effects of the consumption of alcohol on sexual behavior. The effects of alcohol are balanced between its suppressive effects on sexual physiology, which will decrease sexual activity, and its suppression of sexual inhibitions. A large portion of sexual assaults involve alcohol consumption by the perpetrator, victim, or both.
The hormonal theory of sexuality holds that, just as exposure to certain hormones plays a role in fetal sex differentiation, such exposure also influences the sexual orientation that emerges later in the individual. Prenatal hormones may be seen as the primary determinant of adult sexual orientation, or a co-factor.
Sexual motivation is influenced by hormones such as testosterone, estrogen, progesterone, oxytocin, and vasopressin. In most mammalian species, sex hormones control the ability and motivation to engage in sexual behaviours.
Amy Joy Casselberry Cuddy is an American social psychologist, author and speaker. She is a proponent of "power posing", a self-improvement technique whose scientific validity has been questioned. She has served as a faculty member at Rutgers University, Kellogg School of Management and Harvard Business School. Cuddy's most cited academic work involves using the stereotype content model that she helped develop to better understand the way people think about stereotyped people and groups. Though Cuddy left her tenure-track position at Harvard Business School in the spring of 2017, she continues to contribute to its executive education programs.
The replication crisis is an ongoing methodological crisis in which the results of many scientific studies are difficult or impossible to reproduce. Because the reproducibility of empirical results is an essential part of the scientific method, such failures undermine the credibility of theories building on them and potentially call into question substantial parts of scientific knowledge.
The ovulatory shift hypothesis holds that women experience evolutionarily adaptive changes in subconscious thoughts and behaviors related to mating during different parts of the ovulatory cycle. It suggests that what women want, in terms of men, changes throughout the menstrual cycle. Two meta-analyses published in 2014 reached opposing conclusions on whether the existing evidence was robust enough to support the prediction that women's mate preferences change across the cycle. A newer 2018 review does not show women changing the type of men they desire at different times in their fertility cycle.

Enclothed cognition has been described as the overall influence that clothing has on the wearer's psychological processes. The term was coined by Hajo Adam and Adam D. Galinsky who exhibited the effects of clothing in a 2012 experiment that used white lab coats. They hypothesised that worn attire affects the wearer’s psychological processes due to the activation of abstract concepts through its symbolic meaning.
