Sigmund Freud's psychoanalytic theory was based on the opinion that the human personality is composed of three components: Id, Ego and Superego. These three components are arranged along a hierarchical order with the id at the basal end, the ego at the center and the superego at the top. The id at its core seeks instant pleasure and fulfillment, guided by the pleasure principle. The id wants what it wants, when it wants it; whether or not that particular desire or need can be satisfied. The presence or logic of reality or social behavior have no effect on the id. For example, if a child is thirsty and sees a bottle of water, he will take the bottle and drink even if it belonged to someone else and he did not. He is guided by the reality principle in an attempt to rationalize the situation and acts accordingly in order to achieve satisfaction by doing so in a socially acceptable manner. The Ego is «like a man on horseback, who must rein in the superior strength of the horse» (Freud, 1923). For example, while at the restaurant Tom is thirsty but he knew that the waiter would return to refill his glass of water, so he waited until then to get a drink, even though he actually just wanted to drink from Mrs. Smith's glass. The Super Ego sits, omnipresent, on high and acts as a moral compass for both the Id and the Ego. McLeod (2008) states that the superego attempts to manage the impulses of the id and convince the ego to think and act towards moralistic rather than simply realistic goals and to strive for perfection. There are two aspects of the superego: the ego ideal and conscience. The ego ideal is the general idea one has of how to behave in order to be classified as an honest member of society; includes norms, rules and standards for good. The methods he used to obtain information and data have raised questions from other scientists. Her research on children was lacking, as was her use of empirical studies, her research was dominated by men and also lacked universality. The theory of Id, Ego and Superego develops from birth to childhood, therefore the use of case studies on adults and the lack of empirical studies do not seem feasible enough to have developed this theory. Firstly there is no guarantee that these adults' memories of their childhood were accurate, there was no concrete and retestable data therefore they lacked reliability and validity secondly the experience of each case and person is different and therefore cannot be used to determine the development of an entire population. Freud's theory was further distorted because it neglected social and environmental aspects, which prevent universality; he was a European man researching other upper-middle-class Europeans whose daily lives and circumstances differed greatly from those of others
