Nowhere in my post was I "emotional". Are you projecting?
Are you sure that you are not a Democrat?
I'm growing quite used to Republicans calling me "Democrat" and Democrats calling me "Republican". The other day, I was called a "racist" by a Democrat on another board, just because I oppose Affirmative Action. Now, I come here and am called "Democrat" by you.
If I have to classify myself, I'm a libertarian. The underlying principle of "conservatism" is "individualism", and I really do see people as individuals.
I read once that reportedly 70% of American "blacks" can trace their heritage directly to Europe, as a result of generations of "race-mixing", so I don't put much stock in the notion of "race" or "race studies", either.
The summary of the study you linked admitted that the "black" children adopted were adopted at a later age, on average, that other factors could've come into play, and that no study is perfect. There are many influences outside the family, particularly if a child attends school.
The study you linked also put "mixed-race" children in the middle IQ group. I have personal experience raising "mixed-race" children. My oldest son, now only age 7, could read at a fifth-grade level by age 5. He would read astronomy books and knew more on the topic than most adults. Last year, my husband introduced him to algebra, and he picked it right up.
So, why is he performing so well? I think the reason is that we homeschool our children, and that is why I said that "education" makes the big difference. Also, we don't teach our children to identify only with certain people, or to define themselves in a limited way, and that makes a big difference, too. This past summer, we sent our oldest to school, and he was way ahead of his classmates, the vast majority of whom were white.
We know other "mixed-race" homeschoolers performing well above other students, too.
Maybe my one child (and probably the other two, though they're too young to tell) plus these other children are exceptions to the rule. But, then again, I know so many "black" people who are intelligent and "whites" and "Asians" who are not that, at this point, I just don't believe the "race statistics".
BTW, I guess you don't support Proposition 54- the Racial Privacy Initiative - on the ballot in CA to stop the CA state gov't from "classifying" people according to race...? It is backed by Republicans and conservatives, while the Democrats and liberals oppose it. Which side are you on, with that one?
IQ debate of "races" or not -- I think the issue is what a family nurtures or holds as a primary focus as a directing force. Part of the reason, IMHO, homeschooled students do so well, and regardless of their skin tone? The focus is upon "real time" education. In other families, the focus might be upon, say, shopping, or camping each weekend and visiting theme parks. Those of Asian descent tend to score higher, and from all that I've witnessed, primarily because the parents are very clearly focused upon "education".
OTOH, years back I met a group of homeschooling families who were not especially focused on the "education" aspect as much as they were on the "socializing" aspects. Result? The students weren't especially academically oriented, and while, academically, they were still ahead of peers in pub ed, these students were more into being cool, impressing each other.
Yep, I've read "The Bell Curve" and numerous other race, mixed race studies concerning intelligence. How is it this country has seen poorly (or if at all) educated parents raise geniuses and very gifted children, regardless or race, creed, ethnicity? My own two cents: It has everything to do with where education is prioritized in a family. Others have said this, written about it. I do concur with this. It's not a "race" can do/can't do. It's a cultural issue.
Kudos! on educating your beautiful children!
