Excerpts from a long and interesting article by Ronald Bailey in Reason...
When it comes to morality, libertarians are often typecast as immoral calculating rationalists who also have a somewhat unseemly hedonistic bent. Now new social science research shows that libertarians are quite moral, just not in the same way that conservatives and liberals are.
University of Virginia social psychologist Jonathan Haidt has done considerable previous work probing the moral differences between American liberals and conservatives, but came to recognize that a significant proportion of Americans did not fit the simplistic left/right ideological dichotomy that dominates so much of our political and social discourse. Instead of ignoring outliers, Haidt and his colleagues chose instead to dig deeper.
The result: A fascinating new study, “Understanding Libertarian Morality: The psychological roots of an individualist ideology”...involving moral surveys of more than 10,000 self-identified libertarians gathered online at the website yourmorals.org...
So what did the study find to be the basis of libertarian moral thinking? It will not surprise Reason readers that 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....
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....Haidt and his colleagues eventually recognized that their Moral Foundations Questionnaire was blinkered by liberal academic bias by failing to include a sixth moral foundation, Liberty. They developed a liberty scale to probe this moral dimension....And guess what? The researchers found that libertarians dramatically outscored liberals and conservatives when it came to putting a high value on both economic and lifestyle liberty. Most dishearteningly, liberals scored two full standard deviations below libertarians on economic liberty....
Clearly, libertarians are not amoral. Rather, standard morality scales do a poor job of measuring their one central and overriding moral commitment.”...
