Well, you claimed that children of parents with higher IQ have more successful children.

That wasn’t my first claim. My first claim was that IQ predicts success.

I pointed out that this is largely due to social factors, to which you replied a non sequitur about how intelligence has a genetic component.

Then I went here because you brought up parents. So not a non-sequitur but a specific reply to your comment.

From that, a reasonable person would assume that you believe that genetics is a major component of IQ, and not just a small contributing factor.

When I specifically said it’s not clear how big of a factor it is. So no, I don’t think a reasonable person would assume that.
