Question

What is the part of the personality that provides a buffer between the id and the outside world?

Answer 1

The Ego

Explanation:

It is well known that the id, ego and superego are in conflict with one another. The id is the selfish side to you while the superego is the moral side to you. The ego's job is to make sure that the needs of both come to a suitable compromise resulting in making you seem socially desirable.
