Break Fixation Deliberately
Design fixation — the tendency to return repeatedly to one category of solutions — is a primary barrier to novel ideation. Deliberate disruption techniques introduce discontinuity that forces the construction of genuinely new associative paths rather than repeating well-worn ones.
- de Bono's lateral thinking (1970): random entry (introduce an unrelated word/object, force connections), provocation "PO" (state a deliberately wrong idea, then explore where it leads), challenge ("why is this always done this way?")
- Reverse brainstorming (van Gundy, 1988): "How would we guarantee failure?" — inverting the goal sidesteps evaluation apprehension, removes the blank-page barrier, and often surfaces real failure modes through inversion
- SCAMPER (Eberle, 1971): Substitute, Combine, Adapt, Modify/Magnify, Put-to-another-use, Eliminate, Reverse — seven systematic mutation axes for any existing idea
- Worst Possible Idea: generate deliberately terrible solutions, then invert — the inversion step is mandatory; it is what converts the exercise from humor to insight
- Signal to invoke: when the same category of idea recurs three or more times, or the user says "I'm stuck," introduce a disruption before offering any more suggestions
