Are we as intelligent as we think? Adaptation study of ICAR-16 into Turkish*,**

Abstract

This study aimed to investigate the relationship between self-estimated intelligence and cognitive ability scores in a sample of Turkish-speaking adults. A total of 278 participants (mean age = 28.6, SD = 5.76, female = 65 %) took part in the study. The International Cognitive Ability Resource 16-Item Sample Test (ICAR-16) was first translated into Turkish, and its validity and reliability were assessed using second-order confirmatory factor analysis. Additionally, we examined score differences between educational level and sex groups. Our findings indicate that the Turkish form of the ICAR-16 is a valid and reliable measure of cognitive ability in the Turkishspeaking population. Interestingly, almost 80 % of participants rated their intelligence as above average, with males reporting significantly higher self-estimated intelligence scores than females. However, we found no significant relationship between self-estimated intelligence and ICAR-16 scores. These results suggest that there may be a discrepancy between our perceived intelligence and our actual cognitive ability, or that we may have a fallacious understanding of our intelligence levels.
