More broadly, I think it's important to note that there's a lot of variance across individuals, to the point where giving generalized advice just isn't very good. I run a lot and eat a fairly typical runner diet with lots of rice and pasta. I don't seem any worse for it, but I surely wouldn't recommend it to someone that was either sedentary or only did light exercises.

My money is on high IQ people making better decisions under stress/pressure/time constraint than low IQ people, on average. I don't think your example is particularly good here. Maybe this will occasionally be swamped by other factors, but on average, I would expect high IQ people to have an even larger advantage over low IQ people under time constraints than when everyone has plenty of time. Tests like the Wonderlic support my contention.
