There's scientific data on the ability to delay gratification in little kids, comparing black to white. Kids are offered one piece of candy now or three pieces later. This can predict criminality as well as other measures of life success. Google if interested.
Recent genetic race science is censored or obscured in various ways so as not to incite racism. Race itself is said not to exist, but I don't feel that way based on what I've seen, but then I'm not a geneticist to be sure. 'Ice people' had to plan ahead to survive, in Africa you could pick fruit off trees year round, as an example.
Basic common sense based on observing the real world doesn't require science for most people.
