Acknowledging the inevitability of inequality in individual talent, as a society, would lead to the most profound change in consciousness imaginable: we would leave behind forever the myth of just deserts. The notion that we more or less receive what we deserve, that our station is determined by our work ethic and talent, is the lifeblood of capitalism, the stuff of the American dream. And that notion is a lie, one promulgated by those deluded by religion into believing in cosmic justice, by those who benefit from our exploitative economic system, and by those who suffer underneath that belief themselves, convinced by centuries of propaganda that they are to blame for their own misfortune.
To recognize that our abilities lie outside of our control would be to strike the hardest possible blow against meritocracy. For it is that belief in the universal availability of success that underpins our entire system; it is the logic that convinces us that our suffering is fair. Tell the truth to people and show them that the deck was stacked against them the whole time, and support for the whole enterprise will collapse.
To a lesser extent, a problem with heritability study samples is that they tend to consist of more middle- and upper-class individuals than a representative sample would have. This is especially true of adoption studies because the poorest families in industrialized nations are usually not allowed to adopt children, nor are parents who have a history of violence, drug problems, or other dysfunctional behaviors. Therefore, the range of environments in these studies is reduced (Mackintosh, 2011), which makes the influence of genetics appear inflated (Nisbett et al., 2012). Adoption studies also cannot investigate the impact of abuse, neglect, and threats to physical safety because governments and adoption agencies try to prevent children from being placed into these extremely negative environments. Therefore, when behavioral geneticists produce a study that genes are a powerful influence on intelligence, it is important to consider the population and the environment that the study was conducted on. Often, the results of behavioral genetics studies will indicate that genes are important – if a person already lives in an industrialized nation in a home where basic needs are met. It is not clear how well these results apply to individuals in severe poverty or in highly unfavorable environments.
