I think this thread is a perfect demonstration of idealism vs realism. Some people are idealistic and believe what they wish were true, even with little to no supporting evidence and mountains of evidence to the contrary. Other people look at reality first and base their beliefs on that.
> I would not believe anyone if they told me they did not rank possible partners in life on a variety of metrics such as health, wealth, tribal affiliations (family/other network), intelligence, humor, etc.
I certainly do, and this is commonplace to the point of cliche. Think of Indian or Chinese arranged marriages where the parents openly and blatantly choose and approve of partners based on what you said: health, wealth, family, etc. It's a documented fact and I've seen it personally that some Chinese parents even disqualify women over 30 or so as partners for their children (to the point there's a word for it: "leftover women"). In the West some people are squeamish about consciously evaluating and ranking people, but everyone still does it, even if it's subconscious, unless you literally throw a dart at at list and pair with whoever you hit. We just talk about it indirectly: having a "type", being "compatible", having similar interests, getting along, having things in common, avoiding "red flags".
I at least certainly have based my relationship evaluations based on conscious ranking and metrics, and it's led to the incredibly happy, successful relationship I'm in now.
