No way to predict, sure. But if my memory serves me correctly, the entire theme of Taleb's Black Swan was about accounting for such events. For example, financial hedging; you won't know what event might manifest itself and cause a huge financial disruption (the cause), but you can anticipate "it" happening, in some form, and preparing for it by buying long shot hedges (accounting for the effect).
