^You're the 2nd person who has mentioned that black people seem SJ. I'd be interested to hear why this might be the case. I'm probably wrong in drawing any conclusions, but a lot of the black friends I've had and those I've known seemed predominately SP. Very laid back, easy going, love to have fun, joke around, etc. I think the general population is fairly evenly split between SJ's and SP's, so maybe it's just a matter of not having met a lot of black people who are "N". And that happens with white people too - N's are a minority compared to S's - it's harder to find N friends because there just aren't as many of them.
