You might be onto something there SolidGoldBrass. I think they might also find conventional science boring, because of it lack of in-depth understanding. I have to confess I find physics intensely boring, but that is merely through not having very much knowledge of it (school physics lessons put me off for life)- DH understands things like astrophysics and finds them exciting (if not mind blowing/verging on woo), whereas to me it sound a lot like "blah blah blaah blah"
.
Also, lots of people have a need to believe there is "something else out there", like with the ghosty stuff, because the world we see, hear, touch, taste, smell and can measure is not giving them comfort in their lives. Some will turn to religion, others to woo..
