Decades of research suggest that our political differences are best captured by two dimensions of political ideology. The dual evolutionary framework of political ideology predicts that these dimensions should be related to variation in social preferences for cooperation and group conformity. Here, we combine data from a New Zealand survey and a suite of incentivised behavioural tasks (n = 991) to test whether cooperative and conformist preferences covary with a pair of widely used measures of the two dimensions of political ideology-Social Dominance Orientation (SDO) and Right Wing Authoritarianism (RWA)-and related policy views. As predicted, we find that cooperative behaviour is negatively related to SDO and economically conservative policy views, while conformist behaviour in the form of social information use is positively related to RWA and socially conservative policy views. However, we did not find the predicted relationships between punitive and rule following behaviours and RWA or socially conservative views, raising questions about the interpretation of punishment and rule following tasks and the nature of authoritarian conformist preferences. These findings reveal how cooperative and conformist preferences that evolved to help us navigate social challenges in our ancestral past continue to track our political differences even today.
数十年的研究表明，我们的政治分歧最好用政治意识形态的两个维度来描述。政治意识形态的双重进化框架预测，这些维度应该与合作和群体一致性的社会偏好变化有关。在这里，我们结合了来自新西兰调查和一系列激励行为任务的数据（n=991），以测试合作和从众偏好是否与两种政治意识形态的广泛使用的两个维度（社会支配倾向 SDO 和右翼威权主义 RWA）以及相关政策观点相关。正如预测的那样，我们发现合作行为与 SDO 和经济保守政策观点呈负相关，而以社会信息使用形式的从众行为与 RWA 和社会保守政策观点呈正相关。然而，我们并没有发现惩罚和遵守规则行为与 RWA 或社会保守观点之间的预期关系，这对惩罚和遵守规则任务的解释以及威权主义从众偏好的性质提出了质疑。这些发现揭示了在我们的祖先时代帮助我们应对社会挑战的合作和从众偏好，即使在今天，它们如何继续跟踪我们的政治分歧。
