A total of 383 participants (aged 19 to 66 years) completed the Raven's Progressive Matrices, the Myers-Briggs Type Indicator (MBTI), the Fundamental Interpersonal Relations Orientation-Behavior (FIRO-B), and the California Psychological Inventory-434 (CPI-434). Results showed that IQ was positively correlated with perceiving (MBTI), control (FIRO-B), intellectual efficiency (CPI-434), achievement via independence (CPI-434), and negatively correlated with sensing (MBTI), internality (CPI-434) and norm-favouring (CPI-434), supporting the majority of the hypotheses.

Participants' age was correlated with many measures, particularly intelligence and accounted for a third of the variance in IQ scores. Limitations are considered.
