White privilege is real. If that thought provokes immediate dismissal and denial, that would be the wrong response, as the statistics backing it are all real: the income gaps, the education gaps, the incarceration gaps, the addiction gaps, and so on. But, the fundamental cause of white privilege may not be what you think, as the most important gap is illustrated in the figure below: the intelligence gap. This is not merely a racist dataset. This is among the most established facts in the science of psychology. Brains exist, and the race-IQ gaps exist. The same racial gaps exist for ALL tests related to general intelligence, and there are very many of them (the figure below is of the military AFQT). It does NOT follow from this data that the gaps are GENETIC. The cause could be ENVIRONMENTAL: maybe blacks tend to have bad diet, bad schooling, lead poisoning, and/or so on. But, one way or the other, the fundamental importance of the data is undeniable and should not be dismissed as something only a racist would find important. It explains every aspect of racial differences of privilege, either wholly or in large part, as intelligence score differences are strongly related to everything we associate with privilege, even within each race, and it should be a guiding theory of what explains both the race gaps and the class gaps.
