" He describes how the timing of Nash's schizophrenia is misrepresented in the film. He also describes how Nash was not able to complete any more significant work once he began to develop schizophrenia. Seiler also quotes experts in schizophrenia describing how individuals suffering from schizophrenic delusions are not capable of being productive. This point is supported by Nasar's book because it shows that Nash completed his thesis before he began to suffer from schizophrenia. This shows that there is not a real link between schizophrenia and creative brilliance as the film suggests. Nasar also supports this idea because of the way she describes Nash's life after he develops the symptoms of schizophrenia. At one point Nasar describes Nash's life in Princeton as follows:.

             Nash spent most of his time hanging around the university, including fine hall. Most days he wore a smocklike Russian peasant garment. He seemed, as one graduate student at the time remembered, to "talk to the squirrels." He carried around a notebook, a scrapbook entitled ABSOLUTE ZERO in which he pasted all sorts of things, presumably a reference to the rock-bottom temperature at which all activity ceases. He was fascinated by bright colors (Nasar 285). .

             This is hardly a description of a functioning mathematician still contributing to scholarly research. Instead, it shows that Nash's creative genius was now only being used in ways that made him eccentric, with Nash no longer able to contribute anything significant. This is exactly how Seiler's experts describe schizophrenia, where sufferers are too out of touch with reality to be productive. It must also be noted that Nash's initial thesis that contributed to the development of game theory is the only significant achievement he made in his career. This suggests that Nash's future achievements were limited because of his struggle with schizophrenia. Considering this and considering that Nash made his contribution while not suffering from schizophrenia, it can be seen that the book does not provide any suggestion that schizophrenia can have a positive effect.
