I’m also interested. I can find studies indicating higher IQ women are less likely to get married, but nothing on divorce after the fact.

I may be misremembering, but I seem to recall poorer marital rates, and whether that means more divorce or less marriage I'm no longer sure. I'll see if I can find the article or whatever.
The statistics I was reading yesterday there were multiple categories that had lower marital rates that also coincided with lower divorce rates, women who had completed at least bachelors degree was one of those groups.
