不确定性下选择的保守主义是指只有在现状被主导的情况下，人们才会放弃现状，转而选择另一种选择。Bewley（2002）提出的保守选择标准模型引入了多个决策标准，当所有标准都同意替代方案优于现状时，称为现状占主导地位。我们考虑使用多个标准来评估现状和替代方案，但不能用于对它们进行排名的情况。只有当替代方案比现状更可取时才会被选择，即使第一种方案是根据最坏情况评估的，而第二种方案是根据最好情况评估的。由此产生的模型是一种明显的主导模式，或双重保守主义模式。
Conservatism in choice under uncertainty means that a status-quo is abandoned in favor of some alternative only if it is dominated. The standard model of conservative choice introduced by Bewley (2002) introduces multiple decision criteria, and calls the status quo dominated when all criteria agree that the alternative is better than the status quo. We consider the case when multiple criteria are used to evaluate the status quo and the alternative, but cannot be used to rank them. The alternative is chosen only if it is preferable to the status quo even when the first is evaluated according to the worst-case scenario, and the second according to the best-case scenario. The resulting model is one of obvious dominance, or twofold conservatism.
