But these honest conversations are occurring.
For example, scientists have honestly looked up the "biology" or "DNA" hypothesis. But this hypothesis is not very strong:
- why a "color-of-the-skin" would be linked to IQ when a "color-of-the-eye" would not?
(and also: why some people are so interested in IQ and color-of-the-skin but are not interested as soon as the genetic factor is something less "visible to the eye"?)
- how could there be IQ disparity based on skin color when the human DNA is so strongly mixed that between two white men and one black man, one of the white can easily be genetically closer to the black than the other white? There is no "DNA of Black Men" group: the DNA of black men is as diverse as the one of the white men and mixes totally with the one of the white men.
- why black men placed on different social situations are scored so differently on IQ when they have very similar DNA (same family or even twins separated at birth)
- why white men placed on different social situations are scored so differently on IQ? If you use white men as a way to predict IQ based on sociological factors, you get a formula that also predict black IQ, so science would say that color-of-the-skin is not the relevant factor here.
There are works about IQ and skin colors for ages now, and the discourse seems to always go backwards with people saying "sure, but let's forget that we know it does not make more sense and try again". This is those people who stop the honest, curious and intellectual discussion.
And I'm pretty sure the first reaction to this would be "it's all lies", because instead of an honest, curious and intellectual discussion, a lot of people who want to have this discussion are in fact more interested of pushing for one particular answer. For different reasons, but I think one of these reasons is the same as why the EA movement was popular despite being so flawed: those people want to think of themselves as very deep and very smart, they want to see "counter intuitive and repugnant" things and stroke their ego by explaining how smart they are for not finding it counter intuitive or repugnant. The problem is that they sometimes just take things that are counter intuitive and incorrect, and they force them into "look at me, I'm smart, it's counter intuitive and yet I dare to consider it".
It's basically what the Bostrom says: he says himself that he is attracted by the idea black people have lower IQ because it is the rebel thing to do. But being the rebel thing to do does not mean that it is scientifically correct or scientifically smart (it can sometimes be, and sometimes not be, you have the same odds throwing a coin). Saying "women are biologically less apt to choose their leaders and therefore it makes sense they don't have the right to vote" or "the position of stars in the sky is affecting our lives based on in which months people were born" are both as "counter intuitive" and "repugnant" as the Black IQ discussion.
Also, it's a bit strange, because in the case of the Black IQ question, the hypothesis of "I see black men failing more often, so I guess they are not as smart", is not counter intuitive at all. It is people who have considered this hypothesis and realised it's simplistic and the truth is more complicated who went further than the basic intuition.
