Interesting ... superstitions make you less likely to believe in God? It hardly seems possible, yet apparently it's true, according to several semi-scientific studies.
Apparently, there's only room for one set of superstitions in the average person's mind. If a person believes in the paranormal, or in ghosts, they are considerably less likely to believe in Yahweh, the traditional Judeao-Christian god.
This could be because the three traditional Abrahamic religions strongly discourage all superstition except their own brands; Yahweh is jealous and demands that His followers stick to just His version of the supernatural.
But whatever the cause, I find it fascinating that belief in ghosts and the paranormal is inversely related to belief in Yahweh. I would have guessed the opposite: That if you can find it in yourself to accept one faith-based system of beliefs, other supernatural beliefs would make sense too.
