Audit which constraints are real and which are assumed

List every constraint you’re working under, then test each one for whether it is actually fixed.

Why it works

Solvers routinely over-constrain problems by treating assumptions as facts, a phenomenon related to representational fixity. Explicitly auditing constraints forces each one through a simple test — "if I had to violate this constraint to solve the problem, could I?" — which separates truly fixed constraints (legal, physical) from self-imposed ones that are actually negotiable. Removing even one false constraint often changes the solution space dramatically.

How to do it

1. List every constraint you believe applies to the problem ("must be done by Friday," "can’t cost more than $X," "requires manager approval").
2. For each, ask: "Is this constraint externally imposed and unchangeable, or is it an assumption I’m carrying?"
3. For assumed constraints, ask: "What would happen if I violated this? Is that consequence actually unacceptable?"
4. Remove at least one assumed constraint and generate fresh solutions in the expanded space.

Evidence

Constraint relaxation as a problem-solving technique is supported by research on representational change and insight (Ohlsson, Knoblich). Identifying and removing self-imposed constraints reliably increases the solution space in experimental problem-solving tasks. (observational)

Lab insight problems (matchstick puzzles) may be too clean to fully represent real organizational constraints; the principle transfers but the magnitude of effect may not.

Common mistake

Treating time, budget, and headcount as absolute constraints without checking whether the real constraint is an approval process that is faster to change than assumed.
