Using cluster-analysis, we investigated whether rational, intuitive, spontaneous,
dependent, and avoidant styles of decision making (Scott
& Bruce, 1995) combined to form distinct decision-making profiles that
differed by age and gender. Self-report survey data were collected from 1,075 members of
RAND’s American Life Panel (56.2% female, 18–93 years,
Mage = 53.49). Three decision-making profiles were identified:
affective/experiential, independent/self-controlled, and an interpersonally-oriented
dependent profile. Older people were less likely to be in the affective/experiential
profile and more likely to be in the independent/self-controlled profile. Women were less
likely to be in the affective/experiential profile and more likely to be in the
interpersonally-oriented dependent profile. Interpersonally-oriented profiles are
discussed as an overlooked but important dimension of how people make important
decisions.
