Abstract

OBJECTIVE: Decision aids (DAs) play an increasingly critical role in supporting patients in making preference-sensitive treatment decisions. One largely untested assumption of DA design is that patients should be encouraged to deliberate carefully about their options after being informed of those options. The purpose of the present research is to test the impact of deliberative versus intuitive decision strategies in medical decision contexts. METHOD: In 3 experiments, participants were randomly assigned to make a hypothetical medical decision either intuitively, or using various deliberative strategies. In Study 1, we predicted that deliberation would improve decision confidence while not changing decisions. In Study 2, our aim was to establish whether the observed increase in confidence was due to decision-making effort, confirmation bias, or both. In Study 3, it was predicted that deliberation would cause participants to become more confident in suboptimal decisions. RESULTS: Across 3 studies, participants who deliberated felt better about their decisions and decision process, even when the decision was the same as what would have been chosen intuitively (Studies 1 and 2), and even when the decision was normatively bad (Study 3). Study 2 additionally indicated that participants' confidence was driven by confirmation bias rather than effort justification. CONCLUSIONS: Deliberative tasks may often fail to be an effective debiasing tool, and components of patient decision aids that ask patients to deliberate may serve to improve how patients feel without improving the quality of their decisions.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
