Less flippantly, you should expect people running high-variance strategies to be overrepresented at the top. The people leading countries may go to school and get law degrees, but if they stay the path of doing what everyone else does but better, they end up an unremarkable partner at a law firm or something, not POTUS or Bezos or Musk. They don't have to literally do life-threateningly dangerous things (although I'm sure the propensity correlates and that's what the previous poster was talking about), but they do have to be willing to risk the comfortable life that was all but guaranteed for them.
