Definition
The system remains usable when people opt out, are confused, make mistakes, or withdraw cooperation. Refusal tolerance prevents extraction by endurance by treating refusal as a valid input, not a failure state. Called “human” because it protects humans from being turned into the crumple zone when they refuse.
Tests that show it is in place
- Opt-out or decline flows keep core services available without punitive delays.
- Manual alternatives are staffed and tooled so refusals do not create hidden labor.
