Although he was very intelligent and considered a genius, Nash had difficulty dealing with others. Instead of talking and having fun with other university students, he was busy solving equations. In the film, Nash admitted that he didn't like people and that he thought people didn't like him. Nash was also discouraged when he heard that other students were publishing their own papers when he couldn't even find a topic for his doctorate. However, one day he had a great idea and from there 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 allowed his work to be recognized. Although Nash was afraid of social interactions at first, he eventually made friends, but he only became attached to two people: his wife Alicia and his Charles Herman. Adler's theory of personality can explain John Nash's personality. In parts of the film, he became aggressive because his need to excel in class or achieve something was not being met. Due to his desire to come up with his original idea, Nash began having delusions that made him violent later in life. Kelly's theory of personal constructs may also help explain John Nash's behavior. Kelly believed that alternative interpretations were always available and Nash behaved according to his interpretation of things. Because he thought he was being hunted by Russian spies, he ran away and began to become paranoid.

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 continued to run away, thinking the doctor was a Russian spy (Milnor, 2008). Apparently, John Nash feared for his own safety because he thought they were coming after him because he wanted to quit his job. His case was different from that of the others; However. John Nash was delusional and his delusions led him to believe that someone was going to harm him. He believed that someone.
