Morality in Six Dimensions

The Science of Libertarian Morality - Reason Magazine

Rather than a five-dimensional morality scale, maybe there's a sixth scale that's been overlooked.

In his earlier work, Haidt surveyed the attitudes of conservatives and liberals using what he calls the Moral Foundations Questionnaire, which measures how much a person relies on each of five different moral foundations: harm/care, fairness/reciprocity, ingroup/loyalty, authority/respect, and purity/sanctity. Typically, conservatives scored lower than liberals on the harm and fairness scales—that is, they gave those issues less weight when making moral judgments—and scored much higher on ingroup, authority, and purity.

Haidt and his colleagues eventually recognized that their Moral Foundations Questionnaire was blinkered by liberal academic bias, failing to include a sixth moral foundation, liberty. They developed a liberty scale to probe this moral dimension. Unsurprisingly, the researchers found that libertarians dramatically outscored liberals and conservatives when it came to putting a high value on both economic and lifestyle liberty. Haidt and his colleagues conclude, “Libertarians may fear that the moral concerns typically endorsed by liberals or conservatives are claims that can be used to trample upon individual rights—libertarians’ sacred value.”
