JayMan is an HBd blogger obsessed with IQ, heredity and achievement, and probably Richard Lynn's #1 fan. He claims to be Jamaican, which makes him either the most insanely self-hating black person on earth, or a white Nordicist pretending to be black so he can get away with insulting blacks and everyone else who isn't Northwestern European. Either way, he's an idiot.
Recently he "called me out" on his blog re: my stance on environmental factors in global IQ disparities. I had debated him there about a year and a half ago and easily won, and I guess he's been traumatized by it ever since. He links to that post in his new one, and I wondered why he would want to remind people of his defeat, but when I checked it again I noticed that he'd deleted my final reply to try and make himself look like the winner (you can read the unedited discussion here; the deleted comment is "Mar 27 2012 9:57 AM"). Then when I attempted to reply to his latest "challenge" the other day, he refused to approve that comment too. Just thought you'd want to know what a pathetic, dishonest, chickenshit loser he is...if you couldn't already tell.
Anyway, my response to his nonsense was this study showing that poverty leads to a significant drop in IQ points, and this new one which concludes similarly that the wealth of nations determines "national IQs" (not the other way around).
