Matthew is a brilliant student who seems rather arrogant about his intelligence and academic success. He corrected a comment made by his English teacher in class yesterday. The teacher complimented him for his analytical thinking and provided information to support her comment. After class, Matthew told his buddy that the teacher was wrong. His buddy said, "Well she gave you the source of her information. I don't think you have a leg to stand on." What specific problem-solving attribute is Matthew demonstrating?
