事实上，基因和环境对人类行为、特征和态度的差异有不同的贡献，这是行为遗传学领域的核心。对这些不同贡献的看法可能会影响对人类能动性的看法。我们调查了两个独立的样本（N=301和N=740），以评估有关自由意志，决定论，政治取向，以及基因和环境对21个人类特征的相对贡献的信念。我们发现，奠定估计的遗传对这些特征的影响聚类成四个不同的群体，差异预测人类代理，政治取向和宗教信仰。尽管与这些信念有明显的意识形态关联，但平均奠定估计值和公布的遗传力估计值之间的对应关系很大（r= 0.77）。相信遗传决定论的出现是这些外行估计准确性的适度预测。此外，受过教育的多子女母亲对这些特征的遗传贡献的估计特别准确。
The fact that genes and environment contribute differentially to variation in human behaviors, traits and attitudes is central to the field of behavior genetics. Perceptions about these differential contributions may affect ideas about human agency. We surveyed two independent samples (N=301 and N=740) to assess beliefs about free will, determinism, political orientation, and the relative contribution of genes and environment to 21 human traits. We find that lay estimates of genetic influence on these traits cluster into four distinct groups, which differentially predict beliefs about human agency, political orientation, and religiosity. Despite apparent ideological associations with these beliefs, the correspondence between mean lay estimates and published heritability estimates for the surveyed traits is large (r=.77). Belief in genetic determinism emerges as a modest predictor of accuracy in these lay estimates. Additionally, educated mothers with multiple children emerge as particularly accurate in their estimates of the genetic contribution to these traits.
