Collective choice mechanisms are used by groups to reach decisions in the presence of diverging preferences. But can the employed mechanism affect the degree of post-decision actual agreement (i.e., preference homogeneity) within a group? And if so, which are the features of the choice mechanisms that matter? Since it is difficult to address these questions in natural settings, we employ a theory-driven experiment where, after the group collectively decides on an issue, individual preferences can be properly elicited. We find that decision mechanisms that promote consensual behaviour generate substantially higher levels of post-decision actual agreement compared to outcome-wise identical procedures that incentivise subjects to exaggerate their differences.

协议的良性循环

群体使用集体选择机制在存在不同偏好的情况下做出决定。但是,所采用的机制会影响群体内决策后实际一致的程度(即偏好同质性)吗?如果是这样,哪些是重要的选择机制的特征?由于在自然环境中很难解决这些问题,我们采用了理论驱动的实验,在小组集体决定一个问题后,可以适当地引出个人偏好。我们发现,与鼓励受试者夸大其差异的结果相同的程序相比,促进自愿行为的决策机制产生了更高水平的决策后实际协议。
