Mead believes there is an "I" and a "me." The "I" is the more random and creative section of the mind. The "me" is the way we view ourselves from the perspective of others. The "I" is all about innovation and new ways of thinking while the "me" follows standards of conformity. "I" is what we see in ourselves and "me" is what other people see in us. 

Frued has an opposing theory of the mind with 3 parts. The Id is the primal part of our minds that seeks instant gratification and is obsessed with violence and sex, at least according to Freud. The SuperEgo is the part of the mind that wants us to conform to societies expectations and norms. The Ego is ourself, the core of what we regard as personality. According to Freud the Id and Superego are in competition with each other as far as how we are supposed to behave, sort of like the classic angel and devil on our shoulders. 

Both Mead and Freud agree that there are multiple parts of the self. There are multiple perspectives that disagree in how the individual is supposed to act. In both theories, one piece of the mind wants us to conform to societies standards, "Me" and "Superego," while another piece wants us to live how we want to without seeing the consequences, "Id" and "I." Both psychologists agree that our minds are made up of multiple parts that debate how we behave and act.

The military is one example of a total institution. I should preface this by saying I have not actually served in the military but I am going off of other sources.

In the military, life on and off duty is controlled by a commanding officer. Whether it is a physical fight in the barracks or a bounced check, the commanding officer will be notified and will respond accordingly. The military tries to establish uniformity and trust between its members. In the military, soldiers will have to interact with other soldiers and officers while on active duty. While different branches of the military have different value systems, all branches agree on bravery, honor, and service before self. The military aims to create disciplined, dedicated, and courageous individuals to help aid in combat.

Resocialization occurs during basic training. The main goals of Basic training, or Boot Camp, is to establish the military mindset. Recruits will be forced to adhere to specific schedules, learn traditions, and reprogram them into warriors. The military will verbally berate recruits in order to wither down their spirits and get them into fighting shape. The army resocializes people by forcing them to remain accountable for themselves and by changing their mindsets to fit the army's goal
