Definition
Reversibility is the capacity to test a move, observe consequences, and adapt without paying an irreversible price.
Origin
The concept appears across decision theory, entrepreneurship, and product operations: separate one-way decisions from two-way doors, and maximize learning velocity where reversal is cheap.
Mechanism
A reversible move lowers psychological and operational risk. Lower risk increases action frequency, which increases feedback quality. Over repeated loops, the system compounds adaptation instead of freezing under perfection pressure.
Applications
Useful in experimentation, behavior change, and strategy: define the rollback condition before acting, then run small tests that preserve optionality while still generating real data.
