How Much Money Do You Need to Feel Taller? Impact of Money on Perception of Body Height

Body height is considered to be one of the most important reproductive signals. However, there are only a few publications on what influences the sense of whether we assess ourselves as tall or short. In the present contribution, the psychological impact of money on the evaluation of a person's own height was tested. We performed two experimental studies in which the respondents had contact with different amounts of money and were asked to evaluate their body height with the use of a laser pointer. The first experiment (N = 61) showed that contact with money significantly increased subjective height evaluation, and the effect was independent of participants' real body height. The second experiment (N = 120) replicated the effect of money manipulation. Moreover, it was shown that higher amounts of money increased one's own height estimation more than smaller amounts. Our research shows that money can be used for building one's social position, which is an attractiveness signal that can influence one's own height evaluation.
