Oxytocin, the wonder drug that doesn't do what people thought it did. I'm a bit surprised to not see a reference about that in the blog. Could be that it is from 2007.

From what I remember of those studies, the way oxytocin operates is that it increases reciprocate behavior towards people perceive as in-group, while at the same time lowering reciprocate behavior towards out-groups. There is some link there in connection with kin-selection.

A business that has a oxytocin-rich environment might not be the best place.
