Is Reliance on the Affect Heuristic Associated With Age?

Objectives
With age, decision makers rely more on heuristic and affect-based processing. However, age differences have not been quantified with respect to the affect heuristic, which derives judgments based on positive and negative feelings toward stimuli and concepts. This study examined whether reliance on the affect heuristic is associated with age, whether these patterns vary by task type, and which covariates account for age effects.

Method
In a preregistered study, an adult life-span sample (N = 195, 21–90 years, Mage = 52.95, 50% female, 71% non-Hispanic White) completed a battery of cognitive, personality, and socioemotional covariates as well as 3 established affect heuristic tasks: (a) a risk–benefit task, (b) a dread–inference task, and (c) an affect–impact task. Reliance on affect was indexed through (a) a negative relationship between perceived food risks and benefits, (b) a positive relationship between feelings of dread and statistical inferences about mortality risks, and (c) a positive relationship between affective responses and impact judgments when evaluating catastrophes.

Results
For all 3 tasks, usage of the affect heuristic was documented at the group and the individual levels. Contrary to hypotheses, age was not associated with affect heuristic use for any of the tasks. Affect heuristic indices did not correlate across tasks and showed no consistent associations with the covariates.

Discussion
Results suggest that the use of affect-based heuristics is context- or stimulus-dependent rather than a stable, age-associated trait. Further research is needed to validate the present results across additional domains, tasks, and stimulus types.
