最大最小规则可以用作预防原则的正式版本。本文评估了该决策规则的可行性和直观合理性。主要结论是：（1）预防措施必须对称实施。 (2) 只有当结果在价值上具有可比性时才可能采取预防措施，以便可以确定哪种结果最差。 (3) 预防措施对可能性标准敏感。必须排除遥远的场景，并且很难找到原则性的方法来划定界限。 (4) 预防措施对决策问题的框架很敏感。局部的谨慎可能会加剧全球的不谨慎。
The maximin rule can be used as a formal version of the precautionary principle. This paper evaluates the feasibility and the intuitive plausibility of this decision rule. The major conclusions are: (1) Precaution has to be applied symmetrically. (2) Precaution is only possible when outcomes are comparable in terms of value, so that it can be determined which outcome is worst. (3) Precaution is sensitive to standards of possibility. Far-away scenarios have to be excluded, and it is difficult to find a principled way to draw the line. (4) Precaution is sensitive to the framing of decision problems. Local cautiousness may add up to global incautiousness.
