STC13: Lee LeFever on the art of explanation

Lee LeFever is the founder of CommonCraft, best known for the instructional videos with the drawn paper cut-outs that a hand moves around as a voice explains how stuff works. He presented their approach to explanation which focus on empathy with the audience to foster understanding. (This is part of my coverage of the STC Summit 2013 in Atlanta.)

Explanations are hard and try as you might, they can still fail – as anyone knows who has given driving directions to a stranger and then seen them make the wrong turn.

The key to good explanations is empathy with the “explainee”, so you can explain something in their terms. What gets in the way is the “curse of knowledge” which means we cannot remember what it was like not to know how get to the specialty store or how a cloud service like twitter or dropbox works.

To show how explanations increase understanding, Lee used an explanation scale. First you have little understanding, and you care about the big idea, the “why?” Why should you care about a cloud service, why is this important to you? Once you have the “why?” down, you’re ready for basic understanding of the essentials, the “how”? How does a tool work, how can I use it to my benefit? To get expert understanding, you assemble more and more details for different scenarios – and before long, you have all the knowledge to explain this thing yourself!

Four features can make explanations successful:

Context anchors an explanation in shared experience and creates agreement. We all know what it feels like to have misplaced your keys, and we can agree that it’s very annoying. Context is important to show why something is relevant to you.

Story ties together a problem and its solution in a narrative arc. That can be as simple as: “Bob has a problem. Bob finds a solution. Bob is happy!” Story invites our empathy because we can identify with Bob and root for him. It illustrates facts, such as cause and effect, in real life.

Connections can provide a shortcut to other stories we already know. When the producers of the 1979 science fiction movie “Alien” sought funding, they connected their project to a recent successful movie in three simple words: “Jaws in Space”.

Analogies can emphasize “what’s really going on”. Consider an encounter with a bear and how it sets off your “fight-or-flight” impulse with stress hormones. Now transfer that experience: “Imagine the bear comes home from the bar every night.” This analogy gives you a good impression what it feels like to be the child or partner of an abusive alcoholic.

Lee closed by sharing several examples, both from his CommonCraft videos and elsewhere.
