Okay, from what I know the Bell Curve states that there is only a slight difference between blacks and whites anyway. ...
If the difference in IQ between blacks and whites as groups is about 2% yet the economic differences are 20% don't you see that that is still a problem? Of course it is.
Malachi.
You should search for the threads where we previously debated all this.
The black white difference on IQ tests is 15 points-- about 1 SD, which puts the effect size at 1.0.
As posted earlier, here are some guidelines from the well-respected statistician (who doesn't publish in this area, and gives these estimates as guidelines for science in general), Cohen:
Effect sizes of .2 are considered small, .4 medium and .6 large.
1.0-- the black white difference-- is so large, Cohen has no name for it.
IIRC, only 14% of blacks score average on an IQ test, with only 3% scoring one SD above.
The differences are not trivial, and to the extent that IQ correlates with important life outcomes (which it does-- see previous threads) the group difference here is a likely (but not sole) explanation for why blacks do so poorly when it comes to things like education, ses, etc.
The data are the data.
No non-ignorant person can disupute the fact that: (1) IQ predicts important life outcomes, (2) IQ tests are neither culturally nor legally biased, (3) the 15 point race difference mentioned above is real (i.e., not due to test bias).
The only thing under debate is why.
