Theories of war and peace

Why do people go to war? Are they just naturally aggressive? Are they “blank slates” who are conditioned by rewards and punishments to fight?

A few psychologists have developed theoretical “constructs” that may shed light on these questions. These ideas could prove useful in understanding the apparent readiness of humans to tolerate and participate in wars and other inhumanities at the urging of their political and military leaders.

In this blog, we will discuss some of these theoretical frameworks.

We use the term “constructs” to remind readers that “constructs” are what theories address. That is, philosophers and scientists impose their own theoretical constructions on reality to try to make sense out of it. They invent terms like “aggressive instinct,” “fight or flight,” and “need for power” to try to explain the behaviors they see.

The ultimate test of any theory is its (probably temporary) success in helping people make sense out of the complexities of their experience.

Our goal will not be to convince you of the rightness or wrongness of any theory. Rather, we invite you to consider with us the extent to which the theories help us understand why throughout history so many people (but by no means all of them) have seemed so ready to slaughter and be slaughtered.
