From what I understand of the situation, it was widely believed that twins would be better off raised separately, because it would allow each to develop as a unique person, instead of being constantly treated as half of a single entity, dressed alike, doing the same activities, etc.

Where did you get the "widely belived" thing from, Al Gore?

Sorry, but that’s the facts. There are loads of studies of twins separately adopted, going back at least to the 1930s, showing that it was common practice. The only innovation of this study was to start the study while they were still at the adoption agency. New York, incidentally, didn’t ban splitting twins until 1980.
