"More important" for what and "other factors" from which set?

In regard to social issues, such as the murder rate by race you cited earlier, I'm not compelled to believe blacks are genetically wired to behave poorly and kill more often. Rather, as I've said, I believe there has been an extreme set of circumstances in the U.S. that have led to lots of problems.

What do you think are transmission mechanisms which would show how having, say, great-great-grandparents who were slaves affects you now?

As I've said—and as you've said by saying culture can be persistent through generations—I am who I am, in part, because of who my parents and family are. Of course, genetically. But there is more than this. Partly because of material wealth, partly because of availability of education and the opportunity to learn marketable skills, partly because of access to social and professional networks—Simply, there was a deficit created by slavery that takes a while to even out. Slavery wasn't that long ago.

And again, even apart from slavery, there has been, and continues to be discrimination against African Americans in the U.S. Both legally through segregation and just plain old racism (implicit and explicit).

If we compare it to a 100 meter race, it's not as if this was just a simple 20 meter head start for whites because of slavery; it's also that hurdles have been placed every 10 meters in the African American lane through segregation and discrimination.

Do you think the somewhat worse conditions of the American blacks explain the gap in outcomes looking at the present day?

This is my view, yes. See above.

I cited this earlier.

Imagine something like this type of discrimination is happening at all sorts of levels in the U.S.—Blacks are just less likely to be successful in a professional capacity simply because they discriminated against because are black, and apart from any consideration of actual merit.

So, it takes 15 resumes (instead of 10) to get a callback. Then the black candidate is 33% less likely to score an actual interview from that callback. Then 33% less likely to get to the second interview; 33% less likely to get to the 3rd and final interview.

Then they're employed... How much less likely is it a black person receives a promotion? How much less do they make on average?

Edit: Correct me if I'm wrong, but it seems you discount the idea slavery, segregation and discrimination has had ill effects for African Americans in the U.S. up to the present day...Why is that?
