Super Short Summary

Odd Girl Out: The Hidden Culture of Aggression in Girls by Rachel Simmons explores the covert forms of aggression girls employ due to societal pressures to be "nice" and avoid open conflict, such as backstabbing, rumor-spreading, and exclusion from social groups. Through interviews with girls and women, Simmons unveils the psychological damage caused by these hidden methods and argues for a societal change to allow open conflict as a healthier outlet for anger. The book includes scenarios of bullying that result in serious mental health challenges.
