Participants completed two personality tests and an intelligence test. They were also asked to estimate their intelligence. Correlations indicate that there was no relationship between test-derived IQ at both subscale and total level but that it was related to many personality traits. The regression suggests few associations of demographic, test-derived IQ, or personality trait scores. This paper discusses what IQ estimates are a function of, and limitations are acknowledged.en© 2025 The Authors. Published by Elsevier Ltd.
