One hundred participants with current paranoia and 50 individuals without paranoia were recruited. Using a double-blind randomised controlled experimental design, participants twice held powerful or neutral postures before entering neutral virtual reality social environments. In the paranoid sample, those who held a powerful pose did not significantly increase in feelings of power by the end of testing in comparison to controls (group difference = 0.67, C.I. = −1.12; 1.46; p = 0.098), or decrease in paranoia (group difference = −0.23, C.I. = −1.17; 0.72; p = 0.634). In the non-paranoid sample, there was a small significant increase in powerful feelings by the end of testing in the powerful group (group difference = 1.13, C.I. = 0.23; 2.02; p = 0.013), but no significant decrease in paranoia (group difference = −0.71, C.I. = −2.16; 0.74; p = 0.338). Paranoia status was not a modifier on the relationship between condition and feelings of power. We conclude that power posing results in only very small changes in self-reported feelings of power and has no subsequent effect on paranoia.
