Observing others give & take: A computational account of bystanders’ feelings and actions
Fig 6
Participants punished selfish allocators more often (A & B) and more severely (C & D) than generous allocators and those who split resources equally in both Experiment 1 (A & C) and Experiment 2 (B & D). Surprisingly, participants also punished generous allocators more frequently than allocators who split the money equally in Experiment 2 (B & D) and punished them the same in Experiment 1 (A & C). Grey dots show the proportion of trials on which each participant punished each allocator (top panels) and the mean amount of punishment per allocator for each participant (bottom panels). Red diamonds represent the averages of these means. The box plots show the distribution of the participants’ mean punishment per allocator: boxes indicate 25–75% interquartile range, whiskers extend from the first and third quartiles to the most extreme data point within 1.5 × interquartile range, and the median is shown as a horizontal line within this box. * p < 0.05, *** p < 0.001.
