If Math Is The Aspirin, Then How Do You Create The Headache?

I'd like you to think of yourself for a moment not as a teacher or as an explainer or a caregiver though you are doubtlessly all of those things. Think of yourself as someone who sells aspirin. And realize that the best customer for your aspirin is someone who is in pain. Not a lot of pain. Not a migraine. Just a little.

Piaget called that pain "disequilibrium." Neo-Piagetians call it "cognitive conflict." Guershon Harel calls it "intellectual need." I'm calling it a headache. I'm obviously not originating this idea but I'd like to advance it some more.

One of the worst things you can do is force people who don't feel pain to take your aspirin. They may oblige you if you have some particular kind of authority in their lives but that aspirin will feel pointless. It'll undermine their respect for medicine in general.[1]
