While it is not easy to find good ideas in sociology, it's not impossible. One useful concept is called "exposure" (I'm not sure a discipline really invented it. It's common sense). It's simple: behavior depends a lot on ease and opportunity. Why am I good friends with the professor next door, and not the guy down the hall? Simply because I bump into my neighbor all the time. Why are children often beaten by women--the less aggressive sex? One reason is because men are around kids less.
This truth has conservative implications. For example, it suggests that if you want to reduce the frequency of marital infidelity, reduce the number of men and women who work together.
The GSS asked: 1) have you ever cheated? and 2) what is your work status? Here are the percentages who have ever been unfaithful:
Percent ever unfaithful (sample size = 7,890 white women--married or previously married)
Works full-time 16.9*
*significantly higher than homemaker
Full-time working women are twice as likely as those keeping house to cheat. In this respect, sex desegregation in the workplace is anti-family.
