I experience this empty seat phenomenon in America, as a regular white man. I noticed it in college. Nobody would sit by me unless they had to, but they were never obvious about it either as far as I could tell. It just seemed like I had some social forcefield around me that pushed people away. I told me wife about it, and we had a laugh. But over the years it continues to manifest itself. I send me wife pictures of me at a full conference with empty seats only around me. I set up experiments to test my theory. At the airport, or even at work, I will deliberately sit in a middle section that would force people to sit next to me. Yet time after time, the seats next to me are the very last to be taken, if at all. I've tried being extra approachable (smile a lot), dull, aloof, be on or off my phone, etc. I am a good looking skinny guy who has excellent hygiene. But I have some negative social forcefield I can't explain.
