Thinking fast and slow is a book that can explain this very well. You have two modes, one is quick snap decision making, system 1, and long form thinking, system 2.
A great example of these systems conflicting is the following question: A bat and ball cost $1.10 – the bat costs one more dollar than the ball, how much does the ball cost? System 1 wants to serve up “ten cents” but system 2, if engaged, will determine that the actual price of the ball is “five cents”
