Next time you experience a tip-of-the-tongue state, don't retrieve the information from memory. Instead, look up the correct answer. Repeat it a few times or write it down to help with encoding.

People that experience the tip-of-the-tongue state often suffer from incorrect practice time. Instead of learning the correct work, they are learning the mistake itself. For example, some music students who claim to practice diligently can get worse over time. This is because they keep on repeating the same mistakes, instead of using deliberate practice. They actually train themselves to make mistakes.
