It also justifies believing things about oneself that have no objective validity. A truly inferior being can justify thinking of himself as superior because of his race membership. He can rationalize any failures or inadequacies and attribute them to the unfair advantage given to those he considers inferior. However, even if there were such a thing as a pure race, that fact would not justify considering that race superior to any other. One might even make a case for the inferiority of such a race.
Nature clearly favors variation.
Chances of survival under varied and changing conditions increase as the species is more varied. Likewise, a species with several varieties of intelligences, as well as individuals with varying degrees of those intelligences, could well be a sign of superiority , at least in terms of the survival potential of the race. It is valuable data, but it is also explosive data because of our racist political history. Such data will inevitably be exploited by white supremacists, twisted for their own political goals and used not to improve racial relations in America but to encourage further racial strife. Such data consists mainly of correlations.
