I'm sorry to say it's mostly original research, though I did do a lot of research into the studies people have done on the various emotions and particularly their physical manifestations. I did not keep references because I was lazy and generally don't do that (this is not academic work and I absolutely want to keep it readable for non-academics). Regarding rules, I suspect we apply different sets of rules in different situations. Running a red light breaks "would the cops catch me?" yet does not break "would my friends be angry with me?" I've not looked into habits much. They are obviously powerful shortcuts that save on cognitive workload.
