The Science of Libertarian Morality - Reason Magazine:

"...A fascinating new study, “Understanding Libertarian Morality: The psychological roots of an individualist morality,” to be published in a forthcoming issue of The Journal of Personality and Social Psychology. In probing the moral thinking of libertarians, the study uses the “largest dataset of psychological measures ever compiled on libertarians,” involving moral surveys of more than 10,000 self-identified libertarians gathered online at the website yourmorals.org, run by Haidt and colleagues.

...the study found that libertarians show (1) stronger endorsement of individual liberty as their foremost guiding principle and correspondingly weaker endorsement of other moral principles, (2) a relatively cerebral as opposed to emotional intellectual style, and (3) lower interdependence and social relatedness.

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 and much higher on Ingroup, Authority, and Purity scales. In this case, libertarians scored low on all five surveyed moral dimensions. “Libertarians share with liberals a distaste for the morality of Ingroup, Authority, and Purity characteristic of social conservatives, particularly those on the religious right,” notes the study. Libertarians scored slightly below conservatives on Harm and slightly above on Fairness. This suggests that libertarians “are therefore likely to be less responsive than liberals to moral appeals from groups who claim to be victimized, oppressed, or treated unfairly.”

The Schwartz Value scale measures the degree to which participants regard 10 values as guiding principles for their lives. Libertarians put higher value on Hedonism, Self-Direction, and Stimulation than either liberals or conservatives and they put less value than either on Benevolence, Conformity, Security, and Tradition. Like liberals, libertarians put less value on Power, but like conservatives they value Universalism less. Universalism is defined as “understanding, appreciation, tolerance, and protection of the welfare of all people and nature.” All three put high value on Achievement. Taking these results into account, Haidt concludes that “libertarians appear to live in a world where traditional moral concerns (e.g., respect for authority, personal sanctity) are not assigned much importance..."
