Acts as a mediator between the ID and the Superego
Explanation:
So how is the battle between the id and superego handled? The ego, like a judge, listens to both the id and superego. Then it employs the reality principle to determine if the demands of the id can be met without breaking the rules of the superego. The ego is the great compromiser, as it works to find ways to get what a person wants in the real world. Since its focus is on reality, it lies mostly within the conscious and preconscious mind.

He said the ego acts as a person's conscience. When it say right in the reading, "According to the story Pinocchio, you should “always let your conscience be your guide.” For Freud, your conscience is your superego. It’s the voice inside your head that tells you what you should do, instead of what you want to do"
