关于人类遗传变异的民间信仰在种族分类和评估中发挥什么作用？在两项研究中，作者评估或操纵了参与者对人类共有遗传物质百分比的估计，并检验了该变量是否可以预测黑人-白人种族构成中单调变化的面孔的分类（研究 1）和评估（研究 2）。在这两项研究中，具有低（相对于高）基因重叠信念的参与者隐含地认为种族之间的界限更加离散。即使控制了认知需求、政治意识形态、本质主义信仰和“实体”信仰等变量，这些结果仍然很重要。这些发现表明，相信所有人都拥有相似（与不同）的基因构成可能是形成种族分类的关键假设。
What role do folk beliefs about human genetic variation play in racial categorization and evaluation? In two studies, the authors assessed or manipulated participants' estimates of the percentage of genetic material that human beings have in common and examined whether this variable would predict categorization (Study 1) and evaluation (Study 2) of faces that varied monotonically in Black–White racial composition. In both studies, participants with low (vs. high) genetic overlap beliefs implicitly perceived the boundary between races to be more discrete. These results remained significant even when controlling for such variables as Need for Cognition, political ideology, essentialist beliefs, and “entity” beliefs. These findings suggest that believing that all people possess similar (vs. different) genetic makeup may serve as a key assumption that shapes racial categorization.
