Groups that lag behind have often blamed their lags on wrong-doing by groups that are more successful. Since sainthood is not common in any branch of the human race, there is seldom a lack of sins to cite, including haughtiness by those who happen to be on top for the moment. But the real question is whether these sins -- real or imagined -- are actually the reason for different levels of achievement.
Intellectuals, whom we might expect to counter mass hysteria with rational analysis, have all too often been in the vanguard of those promoting envy and resentment of the successful.
This has been especially true of people with degrees but without any economically meaningful skills that would create the kinds of rewards they expected or felt entitled to.
Such people have been prominent as both leaders and followers of groups promoting anti-Semitic policies in Europe between the two World Wars, tribalism in Africa and changing Sri Lanka from a country once renowned for its intergroup harmony to a nation that descended into ethnic violence and then a decades-long civil war with unspeakable atrocities.
Such intellectuals have inflamed group against group, promoting discrimination and/or physical violence in such disparate countries as India, Hungary, Nigeria, Czechoslovakia and Canada.
Both the intellectuals' theory of genetic determinism as the reason for group differences in outcomes and their opposite theory of discrimination as the reason have created racial and ethnic polarization. So has the idea that it must be one or the other.
The false dichotomy that it must be one or the other leaves more successful groups with a choice between arrogance and guilt. It leaves less successful groups with the choice of believing that they are inherently inferior for all time or else that they are victims of the unconscionable malice of others.
When innumerable factors make equal outcomes virtually impossible, reducing those factors to genes or malice is a formula for needless and dangerous polarization, whose consequences have often been written in blood across the pages of history.
