Although he was very intelligent and was considered a genius, Nash found it difficult to deal with other people. Instead of talking and having fun with other students at the university, he was busy solving equations. In the film, Nash admitted that he didn't like people and thought people didn't like him. Nash was also disheartened when he heard about other students publishing their paper while he couldn't even find a topic for his doctorate. However, one day a great idea came to him and from here he started working on his theory which took him decades to finalize. As John Nash told one of his colleagues at the university, he was patient, and that patience led to his work being recognized. Although Nash was initially afraid of social interaction, he eventually made friends but became attached to only two people: his wife Alicia and his Charles Herman. Charles Herman's theory of personality. Adler can explain John Nash's personality. In some parts of the film he becomes aggressive because his need to excel in class or achieve something is not satisfied. Because of his desire to realize his original idea, Nash began to have delusions that made him violent later in his life. Kelly's personal construct theory may also help explain John Nash's behavior. Kelly believed that alternative interpretations were always available and Nash acted according to his interpretation of things.

According to this theory, there are certain needs that people are motivated to satisfy. A person's basic needs are physiological needs including food, water, and shelter. People work hard to satisfy these needs, and John Nash apparently lacked none of these physiological needs. Then, he had to move to the next level, which was the need for security. As shown in the film, Nash worked for the government cracking Pentagon codes. When he met Alicia and fell in love with her; he thought of marrying her so he wanted to leave this job. When the doctor went to the university to take him to the hospital, he kept running away, thinking that the doctor was a Russian spy (Milnor, 2008). Apparently, John Nash became scared for his safety because he thought they were chasing him because he wanted to quit his job. His case was different from that of other people; However. John Nash was delusional, and his delusions led him to believe that someone would harm him. He believed that someone was spying on him and that the Russians were locking him in the hospital to prevent him from doing his top secret work for.
