(Replay) Earning attraction, IQ discrepancy, Market-limiting cues in dating

In today's replay of episode 198, the Dr's discuss: 1. I think that you are absolutely right when you say that happiness comes from esteem, earned in the right way from the people that matter. It's really beautiful to me how that works. But on the other hand, I occasionally meet women who impress me a great deal, strictly based on their DNA- i.e., above-average looks, brains, and personality. Or, as you might expect, even just well above average looks. So my question is, how can attraction be such a profound emotional experience when so much of it is purely on the basis of DNA, and nothing that has been done to earn it? And in fact people are more impressed with someone when it appears that they are not trying? Is how we feel about ourselves based on what we earn, but how we feel about others mostly just a matter of their DNA? 2. How does IQ affect relationships? Specifically, a male having a greater IQ than his female partner, at what point would this cause problems in the relationship and how? 3. I am a recently single 30 year old male, and I've been hitting the online dating apps once again. With my more finely tuned evolutionary lense thanks to your podcast, I've noticed something interestin.  It seems as though most of us, while we want to put our best foot forward in order to increase our chance of success, we still can't help but leak potentially market-limiting queues. Is it simply that we are programmed to be honest so that we don't end up wasting our time with people who wouldn't find these market-limiting interests appealing? Is this a simple energy conservation cost-benefit analysis?
