A person’s economic political views are shaped by their genetic predisposition for cognitive performance interacting with their childhood social class. People with a higher genetic likelihood for cognitive performance tend to adopt left-wing policies if they grew up poor, and right-wing policies if they grew up wealthy. The research was published in Political Psychology. Understanding differences in economic policy preferences is a primary goal of political science. Traditional models in political economics assume that individuals will support policies that benefit them financially. In a strictly theoretical system where flat taxes are redistributed equally, anyone earning below the average income should want complete redistribution, while anyone earning above the average should oppose it. While real political systems are messier, the fundamental dynamic generally holds. Low-income earners tend to benefit from proportional taxation and redistribution, while high-income earners bear the costs. In recent years, researchers have found that genetics also influence political behavior. Studies using various methods have documented genetic overlaps with political preferences. This overlap means that ideological preferences partially share the same genetic architecture as …
