"...Consider these facts. The right wing says it cares about groups, rather than individuals; and yet it favors the most rampant form of 'dog-eat-dog' capitalism. The left wing is suspicious of markets and wants to even the playing field across citizens. The right wing claims that its positions will reduce crime and strengthen the families. Yet it is the most left wing states that have the lowest crime rate and the strongest, most stable marriages. Happiness ratings are highest in the socialist societies, while lowest in right wing authoritarian societies. This list could be extended.
Why, then, do right wing partisans ignore this evidence and continue to support policies that are patently dysfunctional? I believe it is because, having stated a position, based on either their own family values or those dictated by their religion, they are loathe to change their minds and declare that they have been wrong. And so, following Festinger, the disconfirming evidence causes them (or at least many of them) to dig in their heels more deeply.
Another element operates as well. Right wing positions are more frequently associated with Protestant evangelicals and with traditional (Reagan) Catholics. Often the leaders of these groups (e.g. television evangelists, sinning priests) epitomize the opposite of the stated values. But both of these groups embrace forgiveness, absolution, being born again. Other groups—atheists, non-fundamentalist Jews and non-fundamentalist Protestants—do not have the option of absolution; they make firmer demands on themselves and are oppressed by their superegos. Note the 'pass' that non-combatants Bush and Cheney received, in comparison to Gore and Kerry who volunteered to serve during the Vietnam War. Note the forgiving attitude toward to Sarah Palin, with her sinning family, which would never be afforded a comparable Democrat. "What we profess is important—not what we have done"."
