Intelligence, personality, and interests: evidence for overlapping traits

Area of Science:

• Psychology
• Cognitive Science
• Educational Assessment

Background:

• The modern paradigm of intelligence assessment has evolved significantly.
• Distinguishing between intelligence as maximal performance and typical performance is crucial for understanding its application.
• Existing theories of intelligence, personality, and interest offer potential avenues for exploring overlaps.

Purpose of the Study:

• To examine the relationship between intelligence, personality, and vocational interests.
• To evaluate the communality across personality domains and vocational interest models.
• To provide a comprehensive meta-analysis of correlations between personality, interests, and intellectual abilities.

Main Methods:

• Review of theories of intelligence, personality, and interest.
• Analysis of intelligence-as-typical performance for evaluating intelligence-personality and intelligence-interest relations.
• Extensive meta-analysis of personality-intellectual ability correlations.
• Review of interest-intellectual ability associations.

Main Results:

• Consideration of typical performance facilitates the evaluation of intelligence-personality and intelligence-interest relationships.
• Evidence for communality exists across personality constructs and J. L. Holland's model of vocational interests.
• Four distinct trait complexes were identified: social, clerical/conventional, science/math, and intellectual/cultural.

Conclusions:

• Intelligence-as-typical performance is a valuable framework for understanding individual differences.
• Personality, vocational interests, and intellectual abilities are interconnected, forming identifiable trait complexes.
• The findings support a unified view of individual differences across cognitive and affective domains.
