writing tip: Mind Your Anthropology

Found a handy tip entitled Writers' Tricks and Anthropology by S.C. Butler over at Science Fiction & Fantasy Novelists. It basically points out that there are rules for human behavior that should be kept in mind when writing about humans. In particular, he notes that there are studies that show that the optimal number of human interactions is about six. Thus, one should not try to write about a conversation being held in a group larger than that.
