Behavioral Failure Modes
- Wrong target behavior: you picked a behavior users will not perform.
- Remedy: re-rank candidate behaviors with observed data, not opinions. Run a 1-week field probe to measure baseline feasibility.
- Context misfit: the behavior does not fit the real environment.
- Remedy: change the environment or the touchpoint. Move the behavior to where it naturally occurs.
- Ability overestimation: too hard for the median user.
- Remedy: reduce steps, provide scaffolds, and train to fluency before expecting frequency.
- Negative social externalities: social cost blocks action.
- Remedy: provide private paths, reduce visibility, or add credible social proof.
- Time to First Behavior too long.
- Remedy: reduce the steps between the start event and the first beneficial completion. Set a TTFB target from the behavior’s required timing and domain evidence. Targets such as under 5 minutes for a consumer flow or under 1 day for a B2B pilot are starting points, not benchmarks.
- Incentive misalignment: rewards push the opposite behavior.
- Remedy: align incentives with the specific target behavior, not with proxies.
- Brittle reinforcement: behavior collapses when prompts stop.
- Remedy: design intrinsic value and natural triggers that live in the user’s environment.
- Hidden costs: cognitive, time, or money costs are not surfaced.
- Remedy: make costs explicit and reduce or offset them.
Use the Four-Fit Evidence Readiness Checker to see whether the evidence and pre-registered thresholds for each fit are recorded. It does not detect these failure modes or judge initiative viability.
