Anecdotally: I have a pretty decent working relationship with the myriad species of wasps living around our home, in that I can do my gardening work around them without fear of being stung. When my brother who looks very much like me visits he is not investigated to the extent that other visitors are, even when several of us are together in a group.

I realize this isn't entirely germane to the article but it certainly crossed my mind while reading.
