I think that is a good theory on his theory.

In any academic discipline, the only way to make a name for yourself is to come up with something new. It doesn't matter a whole lot whether it's true or not; it just needs to be something different enough to get your colleagues to talk about it, and if you are lucky enough, let it filter down to the public. I couldn't have named very many turkey biologists before Chamberlain came along, but now most turkey hunters know who he is. His career really took off when he started using social media to promote his ideas, and a certain segment believed everything he says.

Bible scholars very much know how to use the idea of something new to make themselves famous and leverage that to a better job. There's not much about the Bible that hasn't been studied endlessly, so it's a challenge to come up with something new, but some of them manage to do it. Those biblical theories don't have much affect on the rest of us. Unfortunately, the turkey theories do.
