Abstract Self-assessed intelligence (SAI) and its correlates have been extensively studied in adults. However, our understanding of how younger people perceive intelligence is limited. The current study aimed to fill this gap by investigating how SAI is associated with objective intelligence, gender, personality traits, and well-being in a sample (N = 428) of high-school students. The results revealed that SAI was not correlated with objectively measured intelligence (Raven's test); however, it was associated with other constructs. First, there were gender differences, i.e. boys' self-estimates of their intelligence were higher than that of girls. Furthermore, SAI was strongly related to grandiose narcissism and moderately related to the personality trait intellect. Additionally, high SAI was associated with high levels of well-being. Finally, SAI accounted for the link between narcissism and well-being as well as that between intellect and well-being. The lack of correlation between SAI and IQ score is consistent with previous findings suggesting that the conception of intelligence in adolescence differs from academic definitions of cognitive ability. On the other hand, the strong association between SAI and narcissism suggests that the concept of intelligence might primarily be a manifestation of boldness and a narcissistic attitude in adolescence.
