The financial cost of status signaling: Expansive postural displays are associated with a reduction in the receipt of altruistic donations

We examined the impact of a nonverbal display (expansive posture) that, by signaling high status, simultaneously cues both low need and high competence, on actual altruistic behaviors: donations of financial aid to needy individuals. Across three studies using ecologically valid data drawn from a micro-lending charity website, men who displayed expansive posture while requesting aid faced a substantial reduction in the amount of aid they received; this effect held controlling for a range of relevant covariates. These findings demonstrate that: (a) altruists bias their giving toward those in greater need rather those who may be more competent, and (b) subtle nonverbal cues of status influence altruistic decision-making.
