Why?
ABE:
I see what you mean: I think the point that people
do hold superstitious beliefs has been dealt with above.
I would add however that it is part of our psychology to belive all kinds of nonsense as it has been shown that how we appraise the world includes a predeliction to superstitious thought (see Borkovec, Halett-Stevens and Diaz, 1999).
We get cause and effect wrong in our heads and it gets reinforced by our up-bringing and culture (as mentioned above).
There is no objective evidence that anything supernatural exist and you will be amazed and aghast at the logic hoops some people will jump through to get around that fact.
