There's a curious phenomenon related to alleged miracles, the paranormal, psychic powers, divination and all kinds of other nonsense: Whenever the phenomenon in question is actually studied and measured, it somehow stops working.
The great James Randi is perhaps the most prominent debunker of such claims, and his method is pretty simple: Let's test if they really work. Somehow they never work in controlled double-blind experiments. Yet invariably the claimants afterward offer all kinds of excuses why it didn't work precisely at that moment. Some even go so far as to directly claim that the very presence of such a skeptic as Randi affects the result.
All these things should be named "quantum powers": They work as long as nobody is actually measuring them. When someone does, they somehow stop working.
