A system, method and article of manufacture are disclosed which implement a training session for training a user to validate assumptions. First, a plurality of stimuli are presented to a user in the context of a simulation. The user is then prompted to enter responses to the stimuli which are subsequently recorded. The user is then allowed to enter assumptions that form a basis of the responses. Next, the user is prompted to enter information on how to validate the assumptions which is subsequently received. Feedback is then outputted based on the stimuli and responses. Such feedback relates to appropriate assumptions and information on how to validate the appropriate assumptions. As an option, the feedback may be further based on a number of assumptions entered.
