Explaining Without the Lecture

Someone told me recently that I’m a bad explainer. My first instinct was to argue, which, if you think about it, is exactly the move of a bad explainer. So I sat with it instead. And the honest verdict is: yeah, fair. When I care about something, I don’t hand it over so much as bury the other person under it. The intent is generous. The impact is a lecture nobody signed up for. That gap has a name in the wild, and it’s not a flattering one. People call it mansplaining, or condescension, or just being a lot, and the sting of those words is that they describe how it landed, not what I meant. Intent and impact are different currencies. You can pay in pure enthusiasm and still hand someone a bill.

Here’s the part that took the personal sting out, though: the failure isn’t a character flaw, it’s a cognitive bug, and it has a tidy lab demo. In 1990 a Stanford grad student named Elizabeth Newton ran a study where she had people tap out a famous song, just the rhythm, finger on a table, while a listener tried to name it. Tappers guessed listeners would get it about half the time. The real number was around two and a half percent. Because inside the tapper’s head the whole song is playing, full band, and they genuinely cannot imagine the silence on the other side. Psychologists call this the curse of knowledge: once you know a thing, you lose the ability to feel what not knowing it is like. Every over-explanation and every under-explanation I’ve ever inflicted on someone traces back to that one bug. I’m not condescending on purpose. I just can’t hear the silence.

So the obvious fix would be to read the room better, to guess what the other person knows before I open my mouth. That’s a trap, and it’s a slower version of the same disease, because now I’m just running my broken model of their knowledge at higher resolution. You don’t beat mind-reading by mind-reading harder. You beat it by not having to. The move is to make the explanation diagnostic instead of broadcast: check in early, drop a relatable anchor and watch whether it catches, and flat-out ask where they want to start. “Do you want the one-line version or the whole machine?” hands them the steering wheel. Teachers have a fancy term for the target you’re aiming at, Vygotsky’s zone of proximal development, the thin band just past what someone already knows where new stuff actually sticks. The thing is, you can’t calculate that band from the outside. You can only find it by reaching out and letting them tell you when you’ve reached too far.

Which is the real reframe: a good explanation is a game of catch, not a monologue. You throw a small piece, you pause, and the pause is not dead air, it’s the most important part. It’s where they get to throw the ball back. Linguists have basically encoded the rule for this. Grice’s maxim of quantity says: be exactly as informative as the moment needs, no more, no less. Over-explaining violates it from above and reads as condescension. Under-explaining violates it from below and reads as showing off. The pause is how you find the line without guessing. When they look lost, you don’t repeat louder, you toss an analogy to bridge the gap. When they’re already nodding ahead of you, you skip the scaffolding and throw them straight to the nuance they actually came for. Either way they’re steering the depth, and you’re just the one with the ball. This is the same muscle as watching your own mind mid-run, pointed outward: you’re tracking, in real time, not just what you know but whether it’s landing.

I want to be a university lecturer someday. The real kind, the one who actually cares about the hour they’re given and isn’t just running out the clock until office hours. And the joke I keep circling is that the best lecturers don’t lecture, they pass the ball so well you don’t notice you’re catching. None of this makes me suddenly good at it. But it turns “I’m a bad explainer,” which sounds like a sentence, into “I haven’t been passing the ball,” which is just a habit, and habits move. The fear underneath all of it was always sounding smart instead of being clear. Turns out the cure for both is the same: shut up half a second sooner, and let the other person tell you where they are. My friends, the ones I’ve talked at instead of with, would probably appreciate me figuring that out about a year ago.
