Rationality quotient (RQ), which has been recently introduced by Keith Stanovich, relies on two hypotheses. First, intelligence and rationality are independent based on narrow view (IQ tests or MAMBIT) (H₁); and, an individual may be high in one and low in another (H₂). This article examined these hypotheses. Participants included (n = 280) students from the social sciences (psychology & sociology) and basic sciences (physics & math). The participants filled out the CART tasks to assess the RQ, and the WAIS-III to assess the IQ. Confirmatory factor analysis (CFA) indicated that IQ and RQ are two factors but positively and significantly correlated. In addition, there was no significant difference among the students with high and low IQs in intellectual errors and biases (RQ) despite Stanovich’s hypothesis.

基思·斯坦诺维奇 (Keith Stanovich) 最近提出的理性商数 (RQ) 依赖于两个假设。首先，基于狭隘观点（智商测试或MAMBIT），智力和理性是独立的（H ₁）；并且，个体可能在一种方面较高而在另一种方面较低(H ₂ )。本文检验了这些假设。参与者包括（n  = 280）社会科学（心理学和社会学）和基础科学（物理和数学）的学生。参与者填写 CART 任务来评估 RQ，并填写 WAIS-III 来评估 IQ。验证性因素分析（CFA）表明IQ和RQ是两个因素，但呈显着正相关。此外，尽管斯坦诺维奇提出了假设，但高智商和低智商学生的智力错误和偏见（RQ）并没有显着差异。
