I understand your point, and I think I understand that of the original parent comment. I don't have much to add, except that believing intelligence is not heritable strikes me as a well thought-out and, in my opinion, largely constructive decision. Up until this very moment, I have always been interested in the reality of this idea; that is, what is true and what is false. Just now it has occurred to me that there is also a political component to this idea, as well as very real moral issue.

After reading through the comments and trying to suss out the logical conclusions of the idea "intelligence is heritable", I have decided to make the same decision.

From here on out, my position is that intelligence is not heritable. This is what I will tell my children and grandchildren. When they ask why, I will tell them that I simply believe it to be true. That it "feels right" to me and the alternative feels truly wrong.

In terms of the science and what is actually happening in the physical world, what measurements and testing actually prove: I am not interested and will not take part in the discussion as I find the idea that intelligence is heritable to be morally wrong. Maybe there is some giant leap humanity could make, and maybe millions of lives could be saved, but I don't care; I think the idea is abhorrent enough that I personally do not want to take the risk.

I'm not trying to preach, but point out that there's more to it than the science and what is objectively real.
