It's not just academics, I've seen the same kind of thinking from lawyers, doctors and business owners. In one sense this isn't a bad thing. It's hard to reason about the world and using our tools and talents to makes sense of it all helps us cope with society. We all have our own religion whether it be spiritual or scientific.
The problem comes when we just hang with our own, in our social networks both in person and online. We start believing that everyone else thinks the same way we do. Then we have difficulty working with people outside our community and that just isolates us even more.
