Freakonomics: A Rogue Economist Explores the Hidden Side of Everything
Steven D. Levitt, Stephen J. Dubner
Reading Freakeconimcs, a book about comparing conventional wisdom to economic data. One of the findings (although small n), was that children who saw a family member suffer through AIDS were less likely to be gay themselves. Which suggests a forcing.
The issue with this issue, of course, is that gaining causal knowledge requires control (or something that effects a natural experiment), and researchers WILL NOT take any controlling role in sexual development, especially of a minor. So, generally speaking the casual agents in sexuality will not be known in any detail.
