Interestingly, I've found these percentages seem to hold true in a variety of other social situations as well. Online dating, for instance - I find I get responses to about 30% of initial messages, but 2/3 of those are just being polite and never strike up a conversation, so I end up with RL dates with about 10% of initial prospects. Haven't met one yet that I felt a real connection to, but I've only been on 8 dates so far, so 1% would imply I've got a few to go.
Or college. I figure I knew (had some interaction with, could name & recognize by sight) perhaps 300 people at my college. Maybe 30 of them I'd call "friends" - I could sit down with them at the dining hall without feeling awkward and chit-chat about classes or hobbies or interests or society and politics. Only about 2 or 3 of them did I really feel close enough to to stay in touch with them after college, once our common interests had ended.
Great insight on this. It tends to hold true for many social aspects. It's something that I take into account when I get rejected or the talk can't go beyond any certain subject/topic because it's nothing personal. The certain wavelength or timing when you met causes the talk to never reach that long-lasting depth.
