I recently came across a paper (Wesselmann, et al. 2015) about chronic ostracism. It seems a relatively new area of research and I'm sure it has its flaws as a model. Anyway, I had no luck finding an at least western world-wise study on the epidemiology and frequencies across regions and countries. By anecdotal and personal experience I have the suspicion that regional culture can influence and boost ostracism among the population by some amount but without tons of reliable data it's just a claim. Is there any statistical study about it?
