We all want to pair with a 10. Let's say my number is 4. But I don't know that. So I might walk over to the woman with the number 10, 9 or 8. They all reject me. Hum, so I'm not an 8. Let me try the 7. Nope. Same with the 6. But the female 5, having faced the same sort of situation and not having approached the male 5, agrees.
Regardless of my personal beliefs about my own attractiveness, the feedback has given me a clue about how society (at least these 10 women) views my attractiveness. While over simplified, we are all getting this feedback, all the time, over the entire course of our lives, about all sorts of things. And we internalize it. To the point that it's hard to distinguish our own sense of self from what we've learned from the feedback of others. Maybe there's no difference? Maybe there is, but how much is internal and how much is learned?
I never put much thought into it but when trying to come up with an answer to this OK Cupid question, the one thing I hear people tell me over and over again ... I'm open minded. People know me well enough to understand that my beliefs may not align with what they are describing and I can be really stubborn (I fight for what I believe in). But they also know that if their is truth in what they are describing that I can see it (which people have said is huge), that I'm willing to admit that I was wrong (to myself and others) and that I'm actually willing to change (which I've learned, in terms of personality, is a big deal).
