Summary: | Much research in
cognitive psychology has focused on the tendency to conserve limited cognitive
resources. The CRT is the predominant measure of such miserly information
processing, and also predicts a number of frequently studied decision-making
traits (such as belief bias and need for cognition). However, many subjects
from common subject populations have already been exposed to the questions,
which might add considerable noise to data. Moreover, the CRT has been shown to
be confounded with numeracy. To increase the pool of available questions and to
try to address numeracy confounds, we developed and tested the CRT-2. CRT-2
questions appear to rely less on numeracy than the original CRT but appear to
measure closely related constructs in other respects. Crucially, substantially
fewer subjects from Amazon’s Mechanical Turk have been previously exposed to
CRT-2 questions. Though our primary purpose was investigating the CRT-2, we
also found that belief bias questions appear suitable as an additional source
of new items. Implications and remaining Keywords: cognitive reflection,
CRT.
