Therefore, if the effects of dispositional affect are playing out through social feedback mechanisms, the relationship of PA and NA with human unfair rejections should be the most marked.
Participants reported that human unfair offers were less fair than computer unfair offers, t 50) = 2.65, p =.01, but that human fair offers were more fair than computer fair offers, t 50) = 3.09, p <.01.
Participants felt more angry to unfair human offers than to unfair computer offers, t 50) = 3.24, p <.01, but did not differ for human and computer fair offers, t < 1. Participants rated unfair offers as less fair than fair offers, F 1, 50) = 424.51, p <.001.
But in 1997 he lost a match to Deep Blue, a chess-playing computer built by I.B.M. Afterward, he accused the computer of getting unfair human help, provoking counteraccusations from members of the snippy chess fraternity, who complained that he had an unsportsmanlike attitude.
Though, the statistical figures presented here are an indication of fair (and sometimes unfair) human practises at SO, the motive of this article is not to make claims, rather, we aim to present a set of questions that need to be answered.
However, men showed a non-significant trend to reject more unfair human offers than women, t(42) = 2.02, P = .05.05
PA was significantly positively related and NA significantly negatively related to both human and computer unfair offer rejection rates, all Ps<.05.
In an ultimatum game in which one player decided how to split a sum of money with another player, human subjects rejected unfair offers from human partners at a higher rate than those made by a computer.
These dispositional findings cannot be simply explained by existing emotion regulation [4] or social regulation [10] [11] accounts of UG behaviour, since dispositional affect did not influence UG behaviour via fluctuations in state affect and showed no differential relationship to human versus computer unfair proposals.
This suggests that enhanced behavioral reaction to unfair human (relative to computer) proposals is not driven solely by bodily feedback mechanisms, and may instead reflect some other, as yet unspecified, mechanisms.
In response it has been argued that just as what counts as fair differs among human communities, what is unfair to humans may not be unfair to another species; researchers should consider natural behavior in order to uncover potential fairness norms (Bekoff & Pierce 2009; Brosnan & Bshary 2010).
