Both definitely contribute. But at the same time the people who stay wizards (and the people you realize are wizards but didn't previously) only appear to be more magical than ever.

Some magic tricks are unimpressive when you know how they are done. But that's not true for all of them. Some of them only become more and more impressive, only truly being able to be appreciated by other masters. The best magic tricks don't just impress an audience, they impress an audience of magicians.
