Final answer:
Intelligence is the trait that does not define personality, as personality traits are stable characteristics such as openness, conscientiousness, extroversion, agreeableness, and neuroticism.
Step-by-step explanation:
Which is not a trait that defines personality?
The trait among the listed options that does not define personality is intelligence. Personality traits are stable characteristics and ways of behaving that can be captured by various models including the Five Factor Model, which includes openness, conscientiousness, extroversion, agreeableness, and neuroticism. These traits are sometimes scored over a continuum, reflecting different degrees of expression. Intelligence, while it can impact behavior and decision-making, is not considered a personality trait but rather an attribute related to cognitive functions and capabilities.
Emotional stability is one of the dimensions identified in the Eysencks' theory, as well as in Cattell's 16 personality factors, which defines how an individual responds emotionally to stresses. Conscientiousness and extroversion are both dimensions found in the widely accepted Five Factor Model and reflect one's degree of organization and social energy, respectively.
