| Summary: | We estimate the
effects of repeated exposure to the Cognitive Reflection Test (CRT) by
examining 14,053 MTurk subjects who took the test up to 25 times. In contrast
with inferences drawn from self-reported prior exposure to the CRT, we find
that prior exposure usually fails to improve scores. On average, respondents
get only 0.024 additional items correct per exposure, and this small increase
is driven entirely by the minority of subjects who continue to spend time
reflecting on the items. Moreover, later scores retain the predictive validity
of earlier scores, even when they differ, because initial success and later
improvement appear to measure the same thing.
