决策惯性是指重复先前的选择而不考虑结果的倾向，这可能导致在次优选择中的坚持。我们调查这种倾向的概率更新任务。研究1表明，当决策惯性与规范最优行为（贝叶斯更新）冲突时，错误率更大，决策更慢。这与决策惯性的双过程观点是一致的，即决策惯性是一个自动过程，与一个更理性、更可控的过程相冲突。我们发现的决策惯性的证据，在需要和自主的决定，但惯性的影响是更清楚的在后者。研究2考虑了更复杂的决策情况下，进一步的冲突，由于强化过程。我们发现相同的影响决策惯性时，强化与贝叶斯更新对齐，但如果后两个过程冲突，影响仅限于自主选择。此外，两项研究都表明，依赖决策惯性的倾向与对一致性的偏好呈正相关。
Decision inertia is the tendency to repeat previous choices independently of the outcome, which can give rise to perseveration in suboptimal choices. We investigate this tendency in probability-updating tasks. Study 1 shows that, whenever decision inertia conflicts with normatively optimal behavior (Bayesian updating), error rates are larger and decisions are slower. This is consistent with a dual-process view of decision inertia as an automatic process conflicting with a more rational, controlled one. We find evidence of decision inertia in both required and autonomous decisions, but the effect of inertia is more clear in the latter. Study 2 considers more complex decision situations where further conflict arises due to reinforcement processes. We find the same effects of decision inertia when reinforcement is aligned with Bayesian updating, but if the two latter processes conflict, the effects are limited to autonomous choices. Additionally, both studies show that the tendency to rely on decision inertia is positively associated with preference for consistency.
