"I would say, "This is what I believe about I.Q. differences, I have 12 different studies that have been published over the years, here’s the journal that's put this stuff together, I believe that this is true, that race predicts I.Q. and that there were I.Q. differences in races." And they would come back with 150 more recent, more well researched studies and explain to me how statistics works and we would go back and forth until I would come to the end of that argument and I'd say, Yes that makes sense, that does not hold together and I'll remove that from my ideological toolbox but everything else is still there. And we did that over a year or two on one thing after another until I got to a point where I didn’t believe it anymore."
