Why "african americans" can never excel at anything relative to the white majority : they can't be the smartest, nor the poorest, nor the best nor the neediest nor the anything else-est. Not ever.
We've been discussing statistics now and again (and again), but apparently nothing's harder "to understand" for common folk than plain, obvious and common sense items they do not wish to even consider, let alone grok.
Let's go again : black people living in the United States can not be the smartest, poorest, best, neediest nor dominate any other normally distributed category of performance however defined because there's just not enough of them.
That's it, and it's sufficient. Here, with visual aids :
The large white space eating the tiny black space represent the relative populations : there's a factor of about 8 separating white and black populations ; and there's a factor of about 8 separating white and black surfaces.
Because the black distribution is so small, you need roughly speaking three standard deviations to match performance equivalent to one single standard deviation in the larger distribution. This is to say that in order to find a black guy who is better than two thirds of the general population at any given task -- being a fireman, or being indigent, or being just about anything else -- you are looking for a black guy that is better than 99.87% than all black guys at the same task.
Yes, you read that right : only the one-in-a-thousand black swan can compare on equal footing with the one third of the general population. You need the best black guy out of one thousand black guys to get a black guy that can compete on equal footing with a white guy that's the best of... a random sample of three dudes.
Which is why (for instance) having anything but white people on, say, Stanford's list of full scholarships for reason of anything (academic performance, economic indigence, anything whatsoever) this year (or any other year) is strictly obscene, as the white guys are not only the most deserving academically and by such a large margin no Ivy league could possibly admit anyone else in any sort of fair contest -- but they're also the neediest, by equally such a large margin that idem.
Where's your "science" now ?
Are you willing to admit it's just bullshit you made up with no basis in reality whatsoever ? Or not just yet ?
Who's gonna provide "just the facts" carefully curated of any actual facts so the sort of rank nonsense you swim in can continue ?
