We translated the International Cognitive Ability Resource sample test (ICAR16) and the Cognitive Reflection Test (CRT) into Danish. We administered the test online to a student sample (N=72, mean age 17.4). Factor analysis revealed a general factor. The summed score of all test items correlated .42 with GPA. Item difficulties correlated .85 with those reported in the Internet norming sample. Method of correlated vectors analysis showed positive relationships between g-loading of items/subtests and their correlation with GPA (r=.53/.85). Model comparisons revealed that for predicting GPA the CRT did not have incremental validity over the ICAR16, but the evidence was not strong.
