When a working-class person votes conservative, isn't he voting against his economic interests? That's what many lefties think and it puzzles them. Why would the workers do such a thing? This gives rise to the duping hypothesis: "the Republican party dupes people into voting against their economic interests by triggering outrage on cultural issues."
Jonathan Haidt demolishes the hypothesis.
According to Haidt, conservatives have a broader "moral palate" than liberals. Liberals have only three concerns to the conservative's six (emphasis added):
. . . we have identified six moral concerns as the best candidates for being the innate "taste buds" of the moral sense: care/harm, fairness/cheating, liberty/oppression, loyalty/betrayal, authority/subversion, and sanctity/degradation. Across many kinds of surveys, in the UK as well as in the USA, we find that people who self-identify as being on the left score higher on questions about care/harm. [. . .]
But on matters relating to group loyalty, respect for authority and sanctity (treating things as sacred and untouchable, not only in the context of religion), it sometimes seems that liberals lack the moral taste buds, or at least, their moral "cuisine" makes less use of them. [. . .]
In America, it is these three moral foundations that underlie most of the "cultural" issues that, according to duping theorists, are used to distract voters from their self-interest. But are voters really voting against their self-interest when they vote for candidates who share their values? Loyalty, respect for authority and some degree of sanctification create a more binding social order that places some limits on individualism and egoism. [. . .]
Despite being in the wake of a financial crisis that – if the duping theorists were correct – should have buried the cultural issues and pulled most voters to the left, we are finding in America and many European nations a stronger shift to the right. When people fear the collapse of their society, they want order and national greatness, not a more nurturing government.
Even on the two moral taste buds that both sides claim – fairness and liberty – the right can often outcook the left. The left typically thinks of equality as being central to fairness, and leftists are extremely sensitive about gross inequalities of outcome – particularly when they correspond along racial or ethnic lines. But the broader meaning of fairness is really proportionality – are people getting rewarded in proportion to the work they put into a common project? Equality of outcomes is only seen as fair by most people in the special case in which everyone has made equal contributions. [. . .]
Similarly for liberty. Americans and Britons all love liberty, yet when liberty and care conflict, the left is more likely to choose care. This is the crux of the US's monumental battle over Obama's healthcare plan. Can the federal government compel some people to buy a product (health insurance) in order to make a plan work that extends care to 30 million other people? The derogatory term "nanny state" is rarely used against the right (pastygate being perhaps an exception). Conservatives are more cautious about infringing on individual liberties (eg of gun owners in the US and small businessmen) in order to protect vulnerable populations (such as children, animals and immigrants).
In sum, the left has a tendency to place caring for the weak, sick and vulnerable above all other moral concerns. It is admirable and necessary that some political party stands up for victims of injustice, racism or bad luck. But in focusing so much on the needy, the left often fails to address – and sometimes violates – other moral needs, hopes and concerns. When working-class people vote conservative, as most do in the US, they are not voting against their self-interest; they are voting for their moral interest. They are voting for the party that serves to them a more satisfying moral cuisine. The left in the UK and USA should think hard about their recipe for success in the 21st century.
