What I've found fascinating is that although most men don't think "more intelligence is better", female intelligence is not inherently unattractive.
If anything, some relatively unintelligent men covet highly intelligent women as potential wives. Perhaps some instinctive urge to improve their gene pool, or some socio-economic ambition. There's definitely more competition for intelligent women than unintelligent ones, and they tend to be more selective, so there's a bit of a trophy-effect to snagging one.
