It seems that my comment section has been infested with racists.
What's the difference between a race realist and a racist? The race realist understands The g Factor, The Bell Curve, and other works of scientific research. The racist apparently thinks that because Barack Obama is half black, it's impossible for him to have a significantly higher g than John McCain.
Go back and read Arthur Jensen. Obama, and his half brother, having IQs of 145, is a fact that's perfectly consistent with everything we know about the science of intelligence.
Most of the people who are making these racist comments have obviously never been to law school so have no idea of how difficult it is to graduate magna cum laude from Harvard (currently set at the top 10% of the class). Law schools have blind grading, and everyone is required to take the same core classes during the first year, and generally another semester of required classes after that. The other three semesters can be filled up with easy seminars, but everyone else at Harvard was doing the same thing. Someone reported that 80% of black law students wind up in the bottom 20% of the class, and that sounds believable. But Barack wasn't one of them.
Also, I may ask, how many people have taken a physics class at an Ivy League university? I have. Believe me, that's not the major that someone who barely got admitted because of affirmative action would choose. The one physics class I had at Penn was the most difficult class I ever took at any university. That Obama's half-brother majored in that stuff, and then got a Masters degree in it, demonstrates that like Barack, he's the real deal, a black person (half-black, actually) with elite cognitive ability.
The most cited arguments against this are:
(1) The way Obama talks in interviews. As I've said before, speaking ability has a low g-loading and writing ability has a high g-loading. Judge Obama by the books he wrote and not by his TV interviews. (But to my ears, Palin is the one who sounds incredibly stupid.)
(2) He hasn't released his test scores and transcripts. Neither has any other candidate. This means that the political system discourages that sort of thing. Some say it's because people want to vote for the guy they'd like to drink beer with, and no one wants to drink beer with a smart person.
(3) Vast left-wing conspiracy to fake Obama's magna designation. I think there's a greater chance that Palin faked her pregnancy. But if you really believe it, go write on every blog you can find (but not mine) that Obama has a fake magna, and see if it causes any new data to come out.
(4) Obama is a liberal. Unfortunately, the elite universities are full of high-g liberals. High g give you the ability to think logically, but many, perhaps most, don't bother to think logically. A lot of intelligent people use their intelligence to create arguements to justify their emotional beliefs rather than use their intelligence to find the correct thing to believe.

People who are upset that Obama has higher g need to reflect on why Republicans are unable to select smart people for high office. Undoubtedly, it's the Christian influence in the party. Most high IQ people reject the simplistic notion that the Bible is the literal word of God. The Evangelical Christians (who are the lowest IQ Christians--the highest IQ Christians are from the mainline Protestant Episcopal and Presbytarian sects) reject candidates who aren't one of them.
