Jim Clark is correct: BSRI was definitely constructed by Sandy, not Daryl, Bem (my undergraduate research mentor in a different life). Also a q for Jim Clark (or anyone else on the list) re: # 3. I agree that MZ twins share more similar intrauterine environments than DZ twins, but my understanding (perhaps a bit outdated now) is that this generally tends to decrease, rather than increase, phenotypic MZ similarity given phenomena like twin transfusion syndrome (which occasionally produces nontriival physical differences within MZ pairs). If Jim or anyone else has any info to the contrary (which there could very well be given that I haven't looked at this literature in a while), I'd be most interested in hearing about it. Thanks in advance, all....Scott

I would be reluctant to rest the continuum idea on Kinsey's work alone. He deliberately selected quite non-representative samples and sought out unusual sexual experiences and practices. Are there sounder data for this claim? 2. I'm not sure why demographics fits in with nature? How about a descriptive node including methods of measurement, notion of continuum, and demographics? 3. Nature question, especially genes, is a tricky one. Monozygotic twins tend to have more similar intrauterine environments (shared placenta, shared chorion) than dizygotic twins, who would be more similar than non-twin siblings. Complicates attributing twin differences to genes, especially given other findings of intrauterine hormonal effects. 4. Depending on audience might expand material on politics of sexual orientation research. I've always found it interesting that gays find idea of genetic cause attractive (not personal choice), whereas genetic explanations for other differences (race, gender) tend to be resisted. 5. Number of spelling errors / typos (homsexuality, temperment, ...) that need correcting and I believe that Bem Sex Role Inventory was constructed by Sandra Bem, not Daryl. Might want to check that out. 6. Concept map shows nice potential, although I could not determine whether it is possible to re-expand nodes after left ones were shrunk to show nodes expanded on right without lower level nodes of some major nodes also opening. That is, can one re-expand and just get the main headings. Take care Jim James M.

The topic, of course, is huge, but I'm going to try to provide a general overview of the various explanations - nature/nurture and in between - for sexual orientation. I've got my notes in a concept map which is starting to get out of hand. Any thoughts/input/feedback appreciated (especially if anything really important is missing).
