But whether you’re an expert or a novice, it’s usually much more straightforward to learn from your successes than your failures. For example, imagine getting your grade back on an exam. If you aced it, you could reasonably assume you made good choices around when, what, and how much to study, and you can replicate those decisions for the next test. But if you failed, it could be for any number of reasons. Maybe you didn’t study enough, maybe you studied the wrong information, or maybe you did everything right and the test covered things you shouldn’t have been expected to know. In cases like this, it’s unclear exactly what went wrong, making it difficult to learn how to improve.
