A common factor called "decision acuity" underpins diverse decision-making abilities. Decision acuity reflects a facility for sound decision-making. High decision acuity reflected fast learning, considering outcomes in the distant future, reward sensitivity, trust in others, and a low tendency for retaliation. Crucially, decision acuity and IQ had dissociable brain signatures. Independent of IQ, decision acuity predicted performance in the decision-making tasks was higher in older subjects and increased parental education.
Decision acuity may be necessary for understanding mental health, inferior social function, and aberrant thought patterns. Decision acuity increased with age and was associated with mental health symptoms independently of intelligence. It was associated with distinctive resting-state networks, particularly in brain regions typically engaged by decision-making tasks. Decision acuity is reliable and stable over months and even years later. Therefore, stable, functional connectivity underpins decision-making ability.
These results may be necessary for understanding mental health, inferior social function, and aberrant thought patterns. Decision acuity is reduced in individuals with low general social functioning. Decision acuity was decreased in those with deviant thinking and low general social functioning.
