Robert Trivers claims in The Folly of Fools that blacks explicitly self-enhance but subconsciously feel that they are inferior. Consistent with this blog's analyses, Trivers cites research indicating that, when asked, blacks inflate themselves more than whites. But Trivers then describes studies that show that blacks implicitly associate whiteness with goodness and blackness with undesirability. They also perform worse on IQ tests when reminded that they are black. Whites, by contrast, associate whiteness with goodness and do a bit better on tests when reminded that they are white. Trivers explains this in terms of identfying with the oppressor: to reduce conflict, victims self-deceive and adopt the view of the exploiter.
In my view, Triver's goofy leftism runs him off the rails here. The fact is that whites are not the oppresors of blacks, and have not been for several decades. It is also a fact that whites are better suited than blacks to life in a civilized society. Perhaps blacks sense this inferiority subconsciously--which is revealed in these studies of subconscious attitudes--but their excessive self-enhancement is manifested consciously. This helps explain phenomena like clownish Afro-centrism. Or perhaps the truth is as simple as whites creating a dominant culture which minorites tend to absorb because it's the water you swim in. The culture doesn't portray whites as superior, but it is mostly made by whites. You might identify with the leader, not because he is exploiting you, but because he is the leader.
For whites, their subconscious self-enhancement is most simply explained as natural: if Trivers is correct, people naturally self-enhance unless there is something to override it.
