Steven Pinker on Terrorism
It's almost time for a deluge of "Ten Years After 9/11" essays. Here's Steven Pinker:
The discrepancy between the panic generated by terrorism and the deaths generated by terrorism is no accident. Panic is the whole point of terrorism, as the root of the word makes clear: "Terror" refers to a psychological state, not an enemy or an event. The effects of terrorism depend completely on the psychology of the audience.
Cognitive psychologists such as Amos Tversky, Daniel Kahneman, Gerd Gigerenzer, and Paul Slovic have shown that the perceived danger of a risk depends on two factors: fathomability and dread. People are terrified of risks that are novel, undetectable, delayed in their effects, and poorly understood. And they are terrified about worst-case scenarios, the ones that are uncontrollable, catastrophic, involuntary, and inequitable (that is, the people exposed to the risk are not the ones who benefit from it).
These psychologists suggest that cognitive illusions are a legacy of ancient brain circuitry that evolved to protect us against natural risks such as predators, poisons, storms, and especially enemies. Large-scale terrorist plots are novel, undetectable, catastrophic, and inequitable, and thus maximize both unfathomability and dread. They give the terrorists a large psychological payoff for a small investment in damage.
Audrey Cronin nicely captures the conflicting moral psychology that defines the arc of terrorist movements: "Violence has an international language, but so does decency."
