The interpretation should be that the odds of a one point increase in
competence results in a 1.407 times higher gender preference. That said,
and without knowing anything about the competence scale, 1.407 seems too
big a value. If you crosstab out cometence score by preference, do you
actually see an odds ratio generally that large?
