He sounds like a typical gifted child if you ask me. The need to have sound knowledge before accepting a fact or making a decision is characteristic. Some things that my son's gifted teacher and I have worked on to help Chance with this are conundrums (questions with NO right answer) and we are starting basic rules of debate as well. Looking at conundrums has helped him realize that there isn't always just one way of looking at a situation, or a single solution to a problem. Basic debate rules are helping him to at least be tactful when arguing a subject, instead sounding arrogant. Another thing I like to do with him, when he's demanding an answer and the facts to support it, is to tell him to go look it up. The answers to almost any subject are available on the internet these days. Having him look up his own answers meets his need for the knowledge, and makes him less dependent on me to be the "know it all".
