What Assumption Inversion does

List the assumptions behind a current approach, flip each to its plausible opposite, and identify where the flipped version is actually true — uncovering new creative directions. Ideal when requirements or designs feel inevitable or unquestioned.

Assumption Inversion is cataloged under AI Engineering on DirSkills. Assumption Inversion comes from a repository tagged agent-skills, brainstorming, claude-code, codex and creativity.

Excerpt

Assumption Inversion

What this technique does

Every approach rests on a stack of unstated beliefs — about who the user is, what they value, how the thing gets delivered, in what order, at what price. List those beliefs, flip each one into its opposite, then ask the sharp question: where is the flipped version already true? Most flips are dead ends, and naming them dead is part of the work. The two or three flips that turn out to be true somewhere are where a non-obvious direction hides — the incumbents never looked there because the original belief felt like a law of nature.
