Some effects of training are delayed. Self-confrontational experiences can have temporary effects. The experience can be temporarily upsetting, and may result in low ratings. If training managers use survey results in evaluating staff, trainers may choose not to confront participants and may even slip into entertainment postures. When the numbers come out of the computer, many trainers pay the most attention to the negative results.
Surveys are about judging others' work rather than taking personal responsibility.
Participants earn their salaries while learning and planning how to apply the learning to their work. Reflect often and honestly about their faults. Have participants' supervisors come to the final session, and have each person declare in front of all the worth of the experience and his or her intended changes. Then gather the data. When they leave, quietly consider the degree of personal integrity in such a strategy.
