The total price of a bat and a ball is 1$ 10 cents. If the bat costs 1$ more than the ball, what is the price of the ball?
The instinctive answer that most people give is 10 cents. System 1 is answering for you if that’s your answer. After doing careful calculations one finds out that the actual price of the ball is 5 cents. Those who curbed their instinct (System 1) to think about the correct answer were governed by System 2. System 1 is controlled dominantly by IP, while System 2 is controlled dominantly by AP.
