Arnold Kling's TCS article, From Far Left To Libertarian, is one of the more interesting things I've read lately:
The question of how I became a libertarian ultimately is a question about how I changed my mental model of the political system from one of "good guys vs. villains" to one of the importance of limited government, individual liberty, and personal responsibility. I travelled the route from Far Left to libertarian. I think that quite a few libertarians have travelled that route, and yet I cannot think of anyone who has gone the other direction. This leads me to suspect that:1. Far Leftists and libertarianism have much in common.
2. Libertarians know something that Far Leftists do not.
I think Kling's ideas apply equally for those who move from conservative to libertarian.
What I believe that Libertarians have learned is what social psychologists call the Fundamental Attribution Error. The error is to attribute behavior to a person's character when this behavior is in fact based on context. In one classic experiment, the subject is asked to watch a person read a speech that the subject knows that the speaker did not write. Subjects attribute to the person the beliefs contained in the speech.The Far Left believes that bad policies come from evil motives. In this view, villains, such as powerful corporations, oppose good policies, and political incumbents lack the strength and courage to overcome the villains.
Libertarians believe that context is more important. We believe that government power is inherently corrupting, regardless of who holds leadership positions or how they are influenced. We believe that the market does a relatively good job of channelling self-interest toward socially desirable ends.
Notice that Kling's point is entirely utilitarian, that libertarianism produces better outcomes, and ignores the ethical point, that coercively managing society is inherently immoral.
A couple of points I should add - Kling's move from 'Far Left' to libertarian is more about the move from elitist societal management to a governmental model emphasizing freedom than anything to do with the more familiar left vs right political model, which is why it also applies to people who move from rightist to libertarian.
Also, if Kling's article gains traction, I'm sure we'll see a number of leftists claiming to be 'former libertarians' in order to discredit him.
