Abstract

Intelligence and rationality both predict optimal decision making. However, whether cognitive rationality (CR) and general cognitive ability (CA) are identical or reflect fundamentally distinct processes is hotly debated. Here, we report a twin study aimed at distinguishing the cognitive mechanisms involved in CR and CA. CR and CA tests were administered to a large twin sample. Univariate analyses indicated that both CA and CR were strongly heritable. Multivariate modelling of CA scales and CR indicated that CR was accounted for by a latent g-factor, which itself was strongly heritable. We conclude that CR is not a distinct disposition from CA, but instead that the reflexive and reflective aspects of cognitive ability make making CR a robust and efficient test of general cognitive ability.

认知理性具有遗传性，属于一般认知能力范畴

智力和理性都能预测最佳决策。然而，认知理性（CR）和一般认知能力（CA）是相同的还是反映了根本不同的过程，这一问题一直争论不休。在这里，我们报告了一项双胞胎研究，旨在区分CR和CA涉及的认知机制。CR和CA测试是对一个大的双胞胎样本进行的。单因素分析表明，CA和CR均具有较强的遗传性。CA量表和CR的多变量模型表明，CR是由一个潜在的g因子引起的，该因子本身具有很强的遗传性。我们的结论是，认知能力测验与认知能力测验并不是一种截然不同的倾向，相反，认知能力的反身性和反思性方面使认知能力测验成为一种稳健有效的一般认知能力测验。
