It also applies to magicians and mentalists, but in a slightly different way. A magician hopeful might watch a magic show and be completely overwhelmed. Eventually they learn their first secrets, and there is a sudden case of "Oh, really? That's it?" and something they were previously enthralled with is now a bit of a bummer. Magic shows become more of a technical puzzle to work out, instead of the spectator amusement they were before learning the secrets. For a while, they forget what it actually was about magic or mentalism that got them so excited. And it is so easy to forget that YOU know the secret, but your audience doesn't. The methods may very well be not so dazzling when you know them, but it's the performance that makes it magical in the first place. And that's where the fun is for the magician or mentalist, and why it's important to not give away their secrets (unless you're like Penn and Teller, where sometimes the secret IS the dazzling part!). Knowledge, to an audience, can immediately make the show very uninteresting. But as the performer, you have to remember they don't have the knowledge you have.
