Predictions are so much easier after the fact. :-)

It seems a little shady for them to claim victory with people staying on the available list year over year. With 120 candidates, how can they not be lucky at least a few times?

I have seen studies that Nobel winners live longer. I'd be interested in the NPV of the career benefits above and beyond the award. Is it more lucrative in some fields than others?
