Chauvinists Earning More?

I have just learned about a research conducted by University of Florida. See the final findings
‘Men in the study who said they had more traditional views of gender roles made an average of about $8,500 more annually than those who had less traditional attitudes controlling for job complexity, number of hours worked and education level.
Delightful.
The situation for women was reversed. More traditional views on gender correlated with decreased earnings — about $1,500 a year less.’
Why am I not surprised? No, seriously, I am not being cynical here!

What I really would like to see though is a study, like this one, showing stats on male and female passion bloggers/web 2.0 bloggers against commercial bloggers. I would be interested in the results.
