All of these categories of failure of rational judgment and decision-making are very imperfectly correlated with intelligence – meaning that IQ tests tend not to capture individual differences in rational thought. Intelligence tests measure mental skills that have been studied for a long time, whereas psychologists have only recently had the tools to measure the tendencies toward rational and irrational thinking.
所有这些类型的非理性判断和决策都与智商毫不相关，也就是说智力测验可能无法捕捉到理性思维方面的个体差异。智力测验评估的是脑力技能，这一技能已经被人们研究多时；而心理学家直到最近才找到测算理性和非理性思维倾向的工具。尽管如此，认知科学近来在理性思维研究上取得的进展意味着：没有什么因素—金钱除外—会阻止我们设立“RQ”测试（理性测试）。
