No, his research staff does. He just talks about their results.
when it comes to his religion he he doesn't dig deeper than the book jacket
Obviously, he has not set that task before his research staff.
You didn't really thinks he comes up with information on his own?
Since I have been listening to Beck from the days when his research staff consisted of himself, Stu and the lady who emptied the trash cans, I believe I have a very sound understanding of how Beck seeks out information.
Beck's primary characteristics are an inquiring mind, common sense and the ability to synthesize information into a discernable picture. Yes, as his popularity and scope has expanded, his staff expanded, however the Beck of today is the same Beck from years ago when there was no staff.
I readily admit that I do not know for a fact that Beck has a thourough knowledge of his religion. However, considering the characteristics he has demonstrated from his early talk show days through today, it seems absurd to believe that in something so important to his life, he would settle for superfulous knowledge.
That is actually a really good point that should be applied to a LOT of media. The talking head rarely ever creates the content. He is nothing more than a mouthpiece for something, someone else wrote on a teleprompter. I have no idea about Beck specifically, but this is pretty much a general rule across the media.
