Too perfect to be good? An investigation of magicians' Too Perfect Theory.

The "Too Perfect Theory" states that if a trick is too perfect, it might paradoxically become less impressive, or give away its secret method. This theory suggests that an increased impossibility results in a less magical effect. The Too Perfect Theory is often applied to magic effects, but it conflicts with recent scientific investigations showing that participants' level of enjoyment of a magic performance is positively related to their perceived impossibility of the trick.
