I don't. From Crooks and Liars Study: Oh Yes, We Can Change Conservative Minds by Susie Madrak - http://crooksandliars.com/2015/02/study-oh-yes-we-can-change-conservative
I've never seen it happen once. The article says it's possible. But ... the real question is ... Is It Probable?
Here's the problem:
Fariss Samarrai, author of the study, American Liberals and Conservatives Think as if From Different Cultures states, " ... political thought was somewhat malleable. They discovered that if they trained holistic thinkers to think analytically, for example, to match scarf with mitten, they would subsequently start viewing the world more liberally (though not on economic policy). Likewise, liberals, if trained to think holistically, would come to form more conservative opinions."
What is the possibility the Right Wing Noise Machine and their minions are even open to training? Have you ever witnessed a FoxNews-viewing-Limbaugh-listening poltroon willing to consider for even one second to look at anything differently? Were not talking about house-breaking a dog here. Were talking about making someone change their world view which is much harder than training a dog to go pee outside.
