Designing for the Nod That Means Nothing
■ Precise language is not legible language
Dr. Koshiba's explanation contains no errors. Stage II, Kaplan-Meier curves — medicine's most precise vocabulary. But jargon compresses information, and it only reaches listeners who can decompress it. What Nakamura received was not content, but the texture of being told something difficult.
■ A vague nod is a failure signal that never gets logged
She nodded and asked nothing. From the speaker's side, the consultation concluded smoothly. Because the person who didn't understand holds the room together with silence, the gap leaves no record. The danger isn't misunderstanding — it's agreement forming while the misunderstanding stays invisible.
■ Conclusion: an explanation succeeds inside the listener
Hakobukun added no new information. It re-encoded the same content as visual structure: progression as position, options as branches, outlook as width. That conversion doesn't depend on vocabulary fluency. "I'll use diagrams from now on" isn't a surrender — it's a design decision to re-select the channel to fit the receiver.
Saying it correctly and saying it so it lands are two different skills.
