An intellectual-yet-idiot who placed too much hope and emphasis on game theory, despite the fact that it only works when agents are perfectly rational.

It might also be fitting to describe NN Taleb. The only one it does not fit, I think, would be Edward Snowden, the last cultural bastion of free speech and human rights protection.
(100,100) (-100,99)
(99,99) (98,98)
The Nash equilibrium strategy is that you pick row 1 and your opponent picks column 1, each receiving 100 points. Once in this state, neither of you can improve by unilaterally changing your strategy. However, if your opponent irrationally deviates and takes column 2, receiving 99 instead of 100, you will get the catastrophic -100 payoff.
