A substantial body of evidence has demonstrated that people vary to the extent they utilize analytic (Type 2) processing when engaging in decision making (analytic cognitive style, ACS). Much of this research discusses ACS as an enduring trait. To date, however, there is no evidence that a greater reliance on Type 2 processing is temporally stable. Here we aggregate data from 11 studies run on Amazon Mechanical Turk in which the Cognitive Reflection Test (CRT) was administered, and identify N = 2,992 unique individuals who completed the CRT twice. We find a strong correlation between an individual’s two CRT scores, r = .792. This is true even when constraining to individuals whose CRT scores were separated by over 2 years, r = .749. Furthermore, we find that CRT scores at time 1 are negatively correlated with belief in God at time 2, r = -.178, and with social conservatism at time 2, r = -.105. Taken together, these results suggest that ACS, as measured by the CRT, is reasonably stable over time.
