But one can detect and judge appearance much more quickly (instantly, in most cases) than personality. It seems much more efficient to select those you consider physically attractive first and then date to check for a compatible character, than the other way round. Just like (excepting bisexuals) most of us instantly disqualify 3.5 billion people as potential partners for being the wrong sex, even if they might have great characters.
You're right, but my point is that by slightly relaxing the physical criteria, you get a wider selection of personalities.
For example, it's ridiculous to ask for an exact height. Height is a spectrum. By demanding 6" or taller, you can't seriously justify how somebody that is 5"9 is an absolute deal breaker.
Similarly, if you're not attracted to fat people, you could still consider somebody a little overweight. Weight is not a static quality.
You may be attracted to brunettes, but I would opt to see that as a preference, not a hard requirement.
My point is that "attractive enough" is a better strategy as all of these things are ultimately unimportant if the personality doesn't match.
