Robin asked “If lawyers and academics can disavow these ancient practices, while still embracing a true essence of law or academia, why can’t religious folks disavow ancient religious practice in favor of some true essence that makes sense in modern terms?”
In “Retreat To Commitment”, Bartley described the (at the time) very large and very powerful group of liberal Protestants who did so disavow ancient views, and look what it got them: demographic replacement by the faithful, by the Evangelists. It only looks like religious folks are different. In truth, after a while we no longer see many folks representing those newer, weaker memes. Isn’t it just normal evolution?
Bob wrote “The person who calls himself a global warming skeptic… after reading a couple of books and a few articles arguing for [such skepticism] will often acknowledge that if he’d started by reading books advocating alternative views, then he would not have come to be a global warming skeptic...” This is one mechanism, but sometimes positions just “feel right” to people, i.e. in agreement with their predisposed visions, or traits.
Also it seemed to me that by asking of people that they examine as many arguments opposed to their view as they examine in alignment with their view, you would also be demanding a similar objectivity from scientists. But as has been said often, scientists are only human. They pursue their hunches (conjectures); and natural selection knew what it was doing when it made all of us normally tend to do the same.
This is not to strongly discount a goal of overcoming bias, but is to confirm a point doubtlessly made here before, that not only does bias exist for a reason but can in many instances be optimal for achievement or survival. Admittedly, truth seeking and achievement may be at odds with one another at times.
