According to the Merriam-Webster Dictionary the definition of superstition is as follows -
1a: a belief or practice resulting from ignorance, fear of the unknown, trust in magic or chance, or a false conception of causation.
b: an irrational abject attitude of mind toward the supernatural, nature, or God resulting from superstition.
2: a notion maintained despite evidence to the contrary.
Now the WT org has printed many articles about avoiding superstitious practices, for example this one 'Are Superstitions Harmless?' Awake!—1987, which in part said "Remember, too, that superstitions offer an immature individual an excuse for blaming some power beyond himself for his bad fortune.”
So why is it that when something appears to go wrong in their lives the majority of the JWs will immediately blame Satan the Devil!
Isn't that just being superstitious?
For example, a friend of ours, due to a mistake in the payroll department of his employer, did not get paid the week before the Regional Convention. "That's the Devil trying to stop me going to the convention" he immediately said. "No, it's a fault with your employer's payroll system." we said. "Yes, but obviously the Devil was behind it. These things don't just happen by chance." Um, yes, they do.
Similarly when a pioneer who was on the first day's programme had a flat tyre en route. "How did that sharp nail just happen to be on the road and me in my good suit having to change a dirty tyre. The Devil's to blame I know!!"
Isn't this just magical thinking and a belief in superstition.
