3. Recall an episode where you experienced the Einstellung effect. How were you able to change your thinking to get past the preconceived, but erroneous, notion?
One episode that occured quite frequently in youth (and less so but still consistently nowadays) was the notion that rote memory is the most effective way to memorize something. Until I read "Moonwalking With Einstein" and realized that the mind memorizes pictures better than words, I would always hammer something until I memorized it. Now, if it's something I really want to approach and get a grasp of, I'll make picture references.
