tough one there, racinchikki. 
I listen to him maybe once a week (I work nights). Basically, he goes both ways. Sometimes the show has completely legitimate scientists, etc. on there talking about exotic topics: Chaos theory, astrophysics, quantum mechanics, the psychiatry of mass murderers, etc.
Sometimes it’s scientists on the edge: ghostbusters, cold fusion
Sometimes it’s completely out there: Mothman, UFOs, conspiricy theories, “shadow people,” black helicopters
My favorite is whe he has no guest and throws it open to the callers. He 'll say “If you are a time traveller, or a person from another dimension, please call now.” And the lines light up. My favorite show was one where he talked to several dozen Antichrists in one night.
Basically, he takes everyone at their word and at face value. What he really thinks is not always clear. Sometimes, with the last group, he lets it slip a little bit and you can “see” him smirking.
He’s a sane man who recognizes that much of his audience is mentally ill, and acts accordingly.
Favorite Art Bell moment:
Caller: I have not been told my destiny yet. I am either the second coming of Christ, or the Antichrist. The Father has not yet revealed to me whether I will save the world, or lead it into eternal damnation.

Art: I can see how you’d want a decision on that.
