The evolution of social power and its role in depression
This chapter explores the theory that depression is about not being able to control one’s social place. Stated briefl y, depression is associated with unfavourable changes in one’s relative social place, or (having a perception of) occupying a low social place. From an evolutionary point of view the questions are: (1) why is social standing and rank so important to humans?; (2) what are the psychobiological correlates of rank position?; and (3) how might the evolved mechanisms and state patterns associated with rank be related to depression?
