The ego is the self as contrasted by another self. Once the ego has developed, it is responsible for mediating between the unrealistic id and the reality. It uses reality to help the id satisfy its demands and to obtain what the ego seeks. Much like the id, the ego seeks out pleasure by reducing tension that has been created and avoids pain. Some other characteristics of the ego are:
- Modified by direct influences
- Decision-making component of the personality
- Works by reason
- Waits for gratification and satisfaction to avoid negative consequences
- No concept of right or wrong
- Something is good as long as there is no harm to self or id
- Weak compared to the id
- Failure to use the reality principle, will experience anxiety
- Works by rational, realistic, and orientated towards problem solving
