Willingness to suspend judgment is another attribute of personality fundamental to scientific behavior. Persons with this attitude accumulate sufficient evidence before making judgments or drawing conclusions. They recognize the tentative nature of hypotheses and the revisionary character of our knowledge. To learn the attitude of suspended judgment, our students should be confronted with situations in which this behavior is rewarded or in some way leads to success while formation of conclusions without evidence leads to failure. Pupils should examine explicitly the consequences of jumping to conclusions.
