I think the major problem is that it&#x27;s easy to fill yourself into thinking that you could have stopped it in hindsight because you already know what happened.<p>If you took this one report more seriously you would have stopped it, sure, but how does that help you going forward? It&#x27;s the same kind of thinking that makes you feel like you could have made a killing buying Microsoft stock or Google or something. Easy to make a post hoc rationalisation that explains the observed facts, likely impossible to do ex ante.
