Pain has shaped our evolutionary history, and pain-free experiences are critical for our health. There are, however, enormous individual differences in pain sensitivity, and the psychological consequences of this heterogeneity are only poorly understood. Here, we investigated whether individual differences in pain sensitivity predicted the experience of unfairness. We found that the magnitude of pain sensitivity correlated with the extent to which participants experienced unfairness. This association was due to the shared human alarm system of unfairness and pain sensitivity. This finding may elucidate mechanisms for producing a new and positive cycle of a healthy experience between fairness and feeling pain-free.
疼痛塑造了我们的进化史，无痛体验对我们的健康至关重要。然而，人们对疼痛敏感性存在巨大的个体差异，而这种异质性的心理后果却知之甚少。在这里，我们研究了疼痛敏感性的个体差异是否能预测不公平感。我们发现，疼痛敏感性的大小与参与者体验到不公平感的程度相关。这种关联是由于不公平感和疼痛敏感性的人类共同警报系统所致。这一发现可能阐明了在公平感和无痛感之间产生健康体验的新的积极循环的机制。
