The concept of power pose originates from a Psychology study from 2010 which suggested that holding an expansive pose can change hormone levels and increase risk-taking behavior. Follow-up experiments suggested that expansive poses incidentally imposed by the design of an environment lead to more dishonest behaviors. While multiple replication attempts of the 2010 study failed, the follow-up experiments on incidental postures have so far not been replicated. As UI design in HCI can incidentally… 
Prior Setting In Practice: Strategies and rationales used in choosing prior distributions for Bayesian analysis
Bayesian statistical analysis is steadily growing in popularity and use. Choosing priors is an integral part of Bayesian inference. While there exist extensive normative recommendations for prior
Prior Setting in Practice: Strategies and Rationales Used in Choosing Prior Distributions for Bayesian Analysis
It is found that participants' experience and philosophy influence how much and what information they are willing to incorporate into their priors, manifesting as different levels of informativeness and skepticism.
Squish This: Force Input on Soft Surfacesfor Visual Targeting Tasks
Results of a visual targeting task for three levels of softness indicate that high force levels appear more demanding for soft surfaces, but that performance is otherwise similar, suggesting force input was underestimated so far.
Some Prior(s) Experience Necessary: Templates for Getting Started With Bayesian Analysis
A set of R code templates that guide Bayesian novices through their first analysis, tailored to CHI, and empirical results for understanding and addressing barriers to using Bayesian analysis in HCI are provided.
Increasing the Transparency of Research Papers with Explorable Multiverse Analyses
Explorable multiverse analysis reports is presented, a new approach to statistical reporting where readers of research papers can explore alternative analysis options by interacting with the paper itself, a step towards more transparent research papers.


Real and imagined power poses: is the physical experience necessary after all?
ABSTRACTPrevious research investigated the effects of power poses at the behavioral, subjective, and neuroendocrine level. However, it is not clear whether the same effects would be obtained also by
Does that pose become you? Testing the Effect of Body Postures on Self-Concept
ABSTRACTSelf-concept expansion predicts a range of adaptive outcomes. An intriguing possible cause of self-concept expansion is the posing of one’s body expansively, that is, “power posing.” In Study
Embodied power, testosterone, and overconfidence as a causal pathway to risk-taking
ABSTRACTPrevious work has found that configuring participants into high-power versus low-power physical postures caused increases in subjective feelings of power, testosterone, and risk-taking as
Assessing the Robustness of Power Posing
A conceptual replication study of the findings of Carney et al. found that power posing affected levels of hormones such as testosterone and cortisol, financial risk taking, and self-reported feelings of power, and found no significant effect of power posing on hormonal levels or in any of the three behavioral tasks.
A Bayesian model-averaged meta-analysis of the power pose effect with informed and default priors: the case of felt power
ABSTRACTEarlier work found that – compared to participants who adopted constrictive body postures – participants who adopted expansive body postures reported feeling more powerful, showed an increase
One perspective on embodiment proposes that bodily states exert direct, context-free effects on psychological states, as in the research on “power poses.” We propose instead that bodily states
Researcher-Centered Design of Statistics: Why Bayesian Statistics Better Fit the Culture and Incentives of HCI
It is shown that Bayesian analysis yields more precise effects with each new study, facilitating knowledge accrual without traditional meta-analyses, and Bayesian methods can be adopted from the bottom up without the need for new incentives for replication or meta-analysis.
Power Posing: P-Curving the Evidence
The existing evidence for the purported benefits of power posing is too weak to justify a search for moderators or to advocate for people to engage in power posing to better their lives.
Is once enough?: on the extent and content of replications in human-computer interaction
What the results mean to HCI, including how reporting of studies could be improved and how conferences/journals may change author instructions to get more replications, is discussed.
Power Posing: Brief Nonverbal Displays Affect Neuroendocrine Levels and Risk Tolerance
Humans and other animals express power through open, expansive postures, and they express powerlessness through closed, contractive postures. But can these postures actually cause power? The results
