~30% is an interesting number in statistics. For example, 33% of Democrats are 9/11 truthers.
30% of people believe in UFOs
Almost 30% of people believe in Astrology and Reincarnation
35% of women believe in Ghosts
..and 32% of people believe in lucky numbers.

I think it is just one of those averages that is a societal norm for fringe beliefs.
