"The cave woman" in you is what I'm exploring for. What I mean by that is I think your positive response to the concept of "intelligence" is the result of it being linked in your mind with something more basic that all women are attracted to, but which they wouldn't characterize as "intelligence". You mentioned confidence, compassion, wisdom, and social grace. Those are all attractive qualities, especially compared to the possible alternatives in a man of low self-esteem, selfishness, foolishness, and social awkwardness. The difference between two such men would stand out loud and clear in a cave dwelling despite there being no discussions of Relativity or 18th Century French Literature. Likewise, the definition you quoted revolves around "reason, sound knowledge, good judgment", rather than, say, " a high mensa ranking, being conversant with quantum physics, being a chess grand master", the latter group being characteristic of a kind of narrowly focused cleverness rather than a broad set of life skills. I think that by "intelligent" you mean a really fine, alert, observant, thoughtful person who is also educated and articulate, and not merely someone who knows 7 languages fluently and can calculate pi to 2000 places in his head.
