How do I explain an idea that sounds strange before someone sees it?
Before you expand a pitch, give an unusual idea a plain explanation. Draft a short version in ordinary words covering who it's for and what they'd encounter, and why that encounter matters to them. Add one concrete moment, then ask a listener to describe it back.
Tyra Banks's description of an unconventional fictional world showed how much an idea can depend on context. Even so, an unusual concept needs a plain explanation that helps someone understand the experience you want to create.
Skip the promotional language and the claims about how new the concept is. Show what a participant, reader or customer would do, then say what that moment reveals about the larger idea. A specific experience is easier to question than a pile of ambitious adjectives.
When the listener describes it back, notice whether they misunderstood the premise or just don't want the experience. Those are different kinds of feedback and need different responses.
Revise the explanation before you expand the pitch. Clarity won't make an unusual idea ordinary, and it will let people decide whether the unusual part interests them. Once they understand it, they can respond to the idea itself.
