Security is both a feeling and a reality, and the two are different things. People can feel secure when they’re actually not, and they can be secure even when they believe otherwise.
This discord explains much of what passes for our national discourse on security policy. Security measures often are nothing more than security theater, making people feel safer without actually increasing their protection.
A lot of psychological research has tried to make sense out of security, fear, risk, and safety. But however fascinating the academic literature is, it often misses the broader social dynamics. New York University’s Harvey Molotch helpfully brings a sociologist’s perspective to the subject in his new book Against Security.
