Neither. It can be educated out of some people, that's largely how I got there. A good scientific education is pretty corrosive to faith if you can generalize it from just the narrow perspective of the science to a broader view of how the world works, but faith in general is just as much alive as it's ever been. It's not going away any time soon, at least not until we get over our fear of death, and even that might not do it. Faith, considered as belief without evidence, and sometimes in the teeth of the evidence, is magical thinking. That's the default for most of us, we are not generally rational critical thinkers. We're capable of rational critical thinking, certainly, but that's a learned skill and it's bloody difficult, both to teach and to learn.
