Combining archival footage, re-enacted scenes, and present-day interviews, it recounts how the brothers discovered one another by chance in New York in 1980 at age 19, their public and private lives in the years that followed, and their eventual discovery that their adoption had been part of an undisclosed scientific "nature versus nurture ...

The authors, born in New York City in 1968 to Leda Witt, daughter of Nathan Witt, were separated as infants, in part, to participate in a "nature versus nurture" twin study. [2] They were adopted by separate families in the New York area who were unaware that each girl had a twin sister. [3]
On the other hand, in an adoption study, participants were adopted at a young age by families without a schizophrenia history. Children with genetic risks (such as having a genetic schizophrenia mother) were more sensitive to negative child-raring styles than those with no genetic risk.
Recent twin and adoption studies indicate that the effect of the shared family environment is significant in early childhood but diminishes substantially by late adolescence. These findings suggest that differences in family lifestyles, while potentially important for many aspects of children's lives, have little long-term impact on the skills ...
At the conclusion of the study in 1980, Neubauer reportedly feared that public opinion would be against the study, and declined to publish it. [10] The records of the study are sealed at the Yale University Library until October 25, 2065, [ 11 ] although by 2018, some 10,000 pages had been released but were heavily redacted and inconclusive.
The first adoption study on schizophrenia published in 1966 by Leonard Heston demonstrated that the biological children of parents with schizophrenia were just as likely to develop schizophrenia whether they were reared by their parents or adopted [5] and was essential in establishing schizophrenia as being largely genetic instead of being a result of child rearing methods.
