Japan Nuclear Accident: Worse than Worst, Again

[pokerfan]

"Worst-case scenario builders consistently underestimate the statistical probability of separate bad things happening simultaneously, as the result of the same underlying causes. <...> Actually, ever major nuclear accident has been worse than worst case, and that's a fact every nuclear advocate--this one included--will have to take into account. As we learned in the global financial crisis as well, instrument and devices thought of as separate entities can all "go south" as the result of a single underlying cause, upending estimates of how likely any one failure would be."
