Putting the Cart in Front of the Horse

This is a little different from my usual posts, but it's an issue that comes up now and again and I want to address it for future reference.

Magic has been around for a very long time, and there are lots of teaching materials and references to choose from if you want to learn. Not all of them are good for beginners however. Show of hands, how many of you have seen a guy say he wants to learn more about mentalism and someone tells him to get Psychological Subtleties? One of the reasons I created my beginner's guide to mentalism is because this happens too often.

Please, do help people. But don't recommend material that you don't already have and don't recommend material that was clearly intended for more intermediate or advanced performers.
