I hate it when your ilk make race vs IQ seem like an edgy new opinion that is being suppressed. It used to be mainstream globally, but we moved past that through dialectics. When the "bell curve" book was published, we resurrected the debate, then we moved passed it.
It seems to me that you have to go out of your way to bring up race and IQ. That's why, whenever the debate is brought up, one of the parties is accused of having an agenda.
No, parent is rightfully pointing out that it's IQ in general, not any specific trait X. X could stand for race/skin color, but it could also stand for ancestry (e.g. Askenazi Jew, which IMO have same skin color as the rest of Europeans), or sex, or maybe other things as well.
For example, any of these studies would drive the internet angry (if they found a strong result):
- Midgets vs IQ
- Attractiveness vs IQ
- Attractiveness vs Likelihood of birth defect
- Wealth vs Emotional Stability
- HN vs Autism Spectrum
- Eye Color vs Empathy
The formula is (visible trait) x (valued trait) x (has this trait already been historically used to justify atrocities).
And, actually, I would argue that in the real world, the correlation isn't even the thing that's problematic, its when the correlation is used as a basis for accepting discrimination on the basis of X. No one is upset about the widely known height/IQ correlation, but that's because no one is using it to justify discriminating based on height, because it is an easily-visible proxy for IQ.
Also suppose trait X is highly visible so that I can easily identify who has it (just for concreteness, let's say it's black eyebrows, and 20 IQ points). This would drive the internet batty.
The same is true if any such correlations are found for a number of other traits.
