Figure 4. Proportions of reward allocations rejected in Experiments 1 (social) and 2 (nonsocial).

Rejections are shown for the disadvantageous inequity condition (A and B) and the advantageous inequity condition (C and D). Within condition, rejections are shown by equal distribution (1–1, A and C) and unequal distribution (1–4 of 4–1, B and D). Participants were assigned either to the disadvantageous inequity condition or to the advantageous inequity condition. Within condition, participants received six equal trials and six unequal trials. Error bars represent 95% confidence intervals.
