Operator Error Is a Time Ratio
The claim
Human error probability in an accident is set by the ratio of time available to time required for the response, not by operator training alone.
01Mechanism
Procedures require a minimum time to execute; when available time approaches it, error probability rises steeply and training cannot compress the procedure further.
02Predictions
- P1Error probability should rise sharply below a time ratio.
- P2Training alone should mispredict.
03Refutation
Error tracking training would remove the time ratio.
