We begin with some definitions:
Social psychology is the study of human cognition and behavior in the context of social groups.
Group. Two or more people who interact, depend somewhat on each other, and have common goals, “those social aggregates that involve mutual awareness and potential mutual interaction.”
Team. A group with more persistent membership
Collective. Two or more people, but with little direct contact with each other.
The differences are not material enough for us to make a distinction, so we use “group.”
In the following, we document the following types of information for behaviors (e.g., group goal setting), phenomena (e.g., team performance), or concepts (e.g., process gain), pathologies (e.g., social loafing), biases (e.g., loss aversion).
For each, we list one or more of the following, depending on the richness of available research, listing both theories and empirical evidence where available:
Typology (what is it?)
Origins, mechanisms, mediators (how does it work?)
Issues, pathologies, biases (what are the problems with its workings?)
Determinants, moderators (what affects it, directly or indirectly?)
