成功的预防往往不会得到奖励

塔勒布设想,一位立法者在 2001 年 9 月 10 日强制给所有驾驶舱安装持续上锁的防弹门。措施真的阻止了袭击以后,公众只会看到成本、麻烦和一场从未发生的灾难。

Who is more valuable, the politician who avoids a war or the one who starts a new one (and is lucky enough to win)?

成功的预防会抹去自己的功劳。没有事故,措施便显得多余;事故发生以后善后的人,反而更容易进入历史。这位沉默英雄也是 Vox clamantis in deserto 的一个例子。

Assume that a legislator with courage, influence, intellect, vision, and perseverance manages to enact a law that goes into universal effect and employment on September 10, 2001;

it imposes the continuously locked bulletproof doors in every cockpit (at high costs to the struggling airlines)

just in case terrorists decide to use planes to attack the World Trade Center in New York City.
