Of course, learning isn’t a perfect process. Sometimes, we forget the details of things that we have already learned. If you find yourself struggling to recall some tidbit of information, research suggests that you are better off simply looking up the correct answer.
One study found that the longer you spend trying to remember the answer, the more likely you will be to forget the answer again in the future. Why? Because these attempts to recall previously learned information actually results in learning the “error state” instead of the correct response.
