Does anyone know of literature on, or have an interest in the application of psychological knowledge and principles to different political parties? I am especially interested in psychological analyses of left-wing parties and voters.
you can try to measure SDO and RWA as ideological components, and explicit and implicit preferences(see for example http://onlinelibrary.wiley.com/doi/10.1111/j.1467-9221.2008.00635.x/abstract)
Are you interested in different sources of social threat and how these impact the growth of authoritarianism? I am thinking of an old piece of research by Leon Festinger called "when prophecy fails" about how a cult adapted to failure in its prophecies. This relates to authoritarianism.
