| description | Proportion responding (PR) is the preference for proportionally
higher gains, such that the same absolute quantity is valued more as the
reference group decreases. This research investigated this kind of proportion
PR in decisions about saving lives (e.g., saving 10/10 lives is preferred to
saving 10/100 lives). The results of two studies suggest that PR does not stem
from an overall tendency to choose higher proportions, but rather from faulty
deliberative reasoning. In particular, people who display PR are less likely to
engage in deliberative reflection as measured by response time, the Process
Dissociation Procedure, the Cognitive Reflection Test, a numeracy test, and a
task assessing denominator neglect. This association between faulty
deliberation and PR was observed only when choosing the highest proportion was
non-normative because it came at the expense of absolute gains (e.g., saving
10/10 lives is preferred to saving 11/100 lives). These results help to make
sense of discrepant findings in previous research, pertaining to how PR relates
to biased reasoning and decision making. |
