Before revision:  However, observed values differed from the model predictions, as less knowledgeable participants overestimated their own capabilities  and assumed greater-than-optimal responsibility.
After revision:  The model generally provided quite accurate predictions of the actual values of the measured responsibility. A bias existed only when participants' classification capabilities were much worse than those of the automated classification system. In this case, the participants overestimated their own capabilities and assumed greater-than-optimal responsibility.
