Thin-slice

If you've ever changed seats on a train or crossed the road to avoid someone, because there was something "not quite right about them", you've used your ability to thin-slice. […] but we thin-slice people in all kinds of situations, not just when we feel threatened.

Of course, first impressions are critical in any context, but especially when there's a potential relationship on the line[…]. That's because humans have a natural desire to "thin slice"—as in, digest small amounts of information (like, what's in your bio) to determine bigger decisions (read: whether this person is worth a date...or more).
