There were several ethical and unethical instances in the film and first I will start off with the ethical. John Nash is awarded the privilege to work for Wheeler Laboratory for making up his own original idea. This is something very honorable and being part of the Wheeler Lab was something of high standards. On the same note, it was very noble of Nash’s opponent, Martin Hansen, to congratulate John Nash on winning the chance to be with the Wheeler Laboratory. The position was a very competitive spot, so when Nash won it was good sportsmanship that Hansen was content with Nash’s success.
As for unethical incidents, here are the few I picked out. Martin Hansen “assumed” that John Nash was the waiter at the table. I say assumed because Hansen was playing dumb and just wanted to insult or tease Nash. Second, Dr. Nash tells his student that his ability to speak comes second to how well Nash can hear himself. This was unprofessional because of the lack of courtesy Nash lacked as a professor. The next point is unethical because it is something frowned upon in society. The way John Nash tries to be with a woman by telling her straight forwardly that he just wants sex. This is not something gentlemanly towards a woman.
John Nash goes through a series of fantasies where he thinks he is involved with a secret part of the government. Nash later is captured by a psychologist and his employees. When taken to the hospital, the director lets the viewer know that Nash is diagnosed with schizophrenia. This psychological disorder makes the diagnosed generate fantasies from the mind and turn them into real life. Although the fantasies are not real to everyone else the diagnosed believes everything they see is real.
