This principle leads people to advocate enormously costly actions to prevent disasters that are even more enormous but whose likelihood highly uncertain. If a disaster is unacceptable, then, no matter how uncertain the likelihood of its occurrence, it must be prevented.
在此原则的指导下，人们倾向于采取大规模而且代价高昂的行动来阻止那些更加巨大，但爆发的可能性也不甚确定的灾难。如果一场灾难非常巨大，那么无论其发生的可能性有多么不确定，都必须被阻止。
