同质性是社会科学中被引用和研究最多的机制之一；它解释广泛的现象的能力是公认的，它可以容纳广泛的相似形式。尽管有这种广度，但相对较少的研究存在，以同源方式区分潜在的选择机制，这些机制将这些不同的基础和结果联系在一起。通过考察同质性的选择驱动因素，我们发展了激进主义者同质性选择的概念，其中同质性吸引的基础不仅是二元相似性，而且还包括对共同结构性障碍的看法，这些障碍源于基于群体成员身份的共同社会认同。我们从理论上分析了这种同质性选择与人际同质性选择的不同之处，人际同质性选择源于两个个体之间感知到的相似性，以及结构层面的诱导同质性。使用实验室实验的数据，我们发现有证据表明，激进分子的选择在很大程度上预测(并在很大程度上中介)女性参与者选择捐赠给一位女性创始人提出的众筹项目。世界上最大的众筹平台的真实数据中出现了一致的结果。
Homophily is among the most cited and studied mechanisms in the social sciences; its ability to explain a wide range of phenomena is well established, and it can accommodate a broad range of forms of likeness. Despite this breadth, comparatively little research exists to distinguish the mechanisms underlying choice homophily that link these varied bases and outcomes. By examining the drivers of choice homophily, we develop the concept of activist choice homophily, where the basis of homophilic attraction is not merely dyadic similarity but rather perceptions of shared structural barriers stemming from a common social identity based on group membership. We theorize how this form of choice homophily differs from interpersonal choice homophily, which emerges from the perceived similarity between two individuals, as well as from induced homophily at the structural level. Using data from a laboratory experiment, we find evidence that activist choice homophily predicts (and largely mediates) the choice of female participants to donate to a crowdfunding project proposed by a female founder. Consistent results emerge in real-world data from the world’s largest crowdfunding platform.
