You're probably on to something. I frequently get impressions like, good Lord, can't you tell this person is schmoozing? Or that they're trying to hide their agitation? Same with people prone to black and white thinking. And it comes after just a minute or two. And it's often right. (Though I constantly doubt myself and possible confirmation bias.) I wouldn't say it's preternatural but better than most people, apparently. I almost never vocalize these impressions. Because the reasons why are inexplicable, and few have any reason to trust my gut instinct over any other person's.
