英文摘要：
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 {\\em obvious dominance}, or {\\em twofold conservatism}.

中文摘要：
不确定条件下选择的保守主义意味着，只有在现状被主导的情况下，才会放弃现状，转而选择某种替代方案。Bewley（2002）提出的保守选择标准模型引入了多种决策标准，当所有标准都认为替代方案优于现状时，就称现状为主导。我们考虑的情况是，使用多个标准来评估现状和替代方案，但不能用于对其进行排名。只有当根据最坏情况评估第一种方案，并根据最佳情况评估第二种方案时，才选择替代方案。由此产生的模型是{\\em明显优势}或{\\em双重保守}之一。
