The average black American IQ is 85 and the average white American IQ is 100. Higher IQ lends itself to more self awareness and hence a higher or even exaggerated sense of one's own flaws. This is why lower IQ people can seem more confident. They just don't have awareness of their own flaws. I read one study that said even poor black children tend to have higher self esteem than white children who are well off.
This is why a 17 y/o blonde Stacy who gets endless validation can think she is a fat pig when she is just curvaceous, while on the other hand, a 275 pound 40 year old black woman will squeeze into the tiniest booty shorts she possibly can in the summer time, wear a halter top with her stretch marked gut hanging out and think she is gods gift to all races of men everywhere. And if you ask her, she mogs 17 year old blonde Stacy to hell and back "dat white gurl beez skinny, I got sum meat on ma bones". She's too low IQ to even suspect that she has any flaws.
Where I used to live, you could see a 48 year old black homeless bum, drug and alcohol addicted, with tattered and dirty clothes, missing teeth, desperately needs a bath, scraggly dirty beard who has sky high confidence and think he can get any woman of any race of any age he wants, just like that. But what do you think his IQ is? He's hardly the sharpest knife in the drawer. All while a suburban Chad is sitting somewhere depressed, over exaggerating in his mind some minor flaw where the black homeless bum believes he's perfect.
I say that the IQ difference and ability to be aware of one's flaws lends itself to the suicide rate differences
