===The Intersecting Psychologies of Gender and Arbitrary-Set Conflict===
*Authors argue:
**Intergroup aggression is mostly driven by men
**'''Subordinate-male target hypothesis''': From this, most people who are victims of intergroup aggression are men 
***This does NOT imply that women are not discriminated against, but that “subordinate males are the primary objects of arbitrary-set discrimination” (Sidanius and Pratto, Chapter 2).
***This hypothesis goes against the '''double-jeopardy hypothesis'''. The double-jeopardy hypothesis states that subordinates ethnicities are discriminated against and women are discriminated against, so a subordinate woman is doubly disadvantaged.
*SDT is distinct from other theories because it incorporates political psychology of gender
====Hierarchical Equilibrium and Hierarchy Constraints====
*Most hominoids organize themselves so that there is some group-based inequality
*Authors argue that level of inequality will stabilize around a certain level, which is called the '''point of hierarchical equilibrium'''
**The point is between HE and HA forces
