Syllabus: Why Do People Harm Others—and What Can Reduce It?
Follow the distinction between an individual's motive and a process sustained by group boundaries, norms, or institutions.
Why you’re reading it. Extend the account of retaliation beyond a single angry encounter.
A question to consider. After one team member harms another, uninvolved members begin retaliating. What might a credible grievance procedure change, and what outcomes could reveal continued or displaced harm?
Why this reading
Retaliation can move from a dispute between individuals into a conflict involving people who were never part of the original event. This review connects motives and emotions with group boundaries, cultural expectations, and institutions.
Before you read
A multilevel account links individual processes with larger social arrangements. Displaced revenge targets another party or entity; vicarious revenge can involve an avenger and target who were both uninvolved in the original offense. A proposed evolutionary function differs from a person's conscious purpose.
Read for
- Separate why revenge might persist, what prompts it now, and how it is expressed.
- Track how group membership changes who is blamed or targeted.
- Ask which evidence supports feedback between individual retaliation and institutional conditions.
Consider afterwards
- How might a grievance procedure interrupt retaliation, and what would show that it does?
- Could a response deter one person while escalating conflict with others?
Editorial context
The review assembles diverse evidence rather than estimating one pooled causal effect. Its historical and evolutionary explanations are hypotheses with different evidential requirements from experiments. The authors call for broader samples and stronger study of dynamics. Explaining revenge's possible functions does not make it desirable or inevitable, nor does prevention require accepting ongoing harm.
