Of course, but there are methodologies that I have not studied in the Social Sciences, other than to know that it is difficult to come up with a good methodology. I could read Kinsey, but it would be foolish to do so since Kinsey's methodologies are known to have been flawed.
As I said, a 1981 work that was actually of value would not be obscure - especially one that had the capacity to prove wrong what we all know to be right - that sexual preferences are learned.
Shalom.
