The second form of schizophrenia is called catatonic. They looked the same and liked many of the same things, yet their personalities were very different. So let's say that you're a scientist and you're very interested in learning about what causes schizophrenia. And even if Eric does an adoption study, he might not fully be able to answer that question.

Both identical and fraternal twins were enrolled in the study at either 11 or 17 years of age. And you might take that as an indication that there's a genetic component. It appears, by evidence of this study, that there is a correlation between biological parents and their children in terms of intelligence. Example Nature is your genes.
