This looks like a brain mechanism finding to back up the well known psychological phenomenon called The Fundamental Attribution Error,[1] "the tendency to overestimate the effect of disposition or personality and underestimate the effect of the situation in explaining social behavior." Simply put, we observe other people's noticeable behavior in social situations (which is most likely to be their BAD behavior, which gains more notice) as reflecting their (bad) character, while we figure that most of our own behavior toward other people is the best we can do under the circumstances. I've seen plenty of examples of this here on Hacker News, and if I acknowledge the research findings, I have to acknowledge that I've provided more than a few examples of that kind of behavior here on Hacker News over the years.
