Bill thought he had a bad day. In the morning, he drove his sister to school, then he worked 12 hours, took her home, and then started dinner. Unfortunately, he burnt the macaroni and cheese he made.
Bill: "I am so stupid! I can't even make macaroni and cheese!"
What is "Disqualifying the Positive?"
Bill helped his sister, worked 12 hours, and is very busy.
Just because he burnt the macaroni and cheese, that does not mean that he is less intelligent. Perhaps he was doing too much at once, but this does not make him "stupid."
