As you stand in endless lines this holiday season, here’s a comforting thought: all those security measures accomplish nothing, at enormous cost:
“The only useful airport security measures since 9/11,” he says, “were locking and reinforcing the cockpit doors, so terrorists can’t break in, positive baggage matching”—ensuring that people can’t put luggage on planes, and then not board them —“and teaching the passengers to fight back. The rest is security theater.”
“Most of the time we assess risk through gut feelings,” says Paul Slovic, a psychology professor at the University of Oregon who is also the president of Decision Research, a nonprofit R&D organization. “We’re not robots just looking at the numbers.” Confronted with a risk, people ask questions: Is this a risk that I benefit from taking, as when I get in a car? Is it forced on me by someone else, as when I am exposed to radiation? Are the potential consequences catastrophic? Is the impact immediate and observable, or will I not know the consequences until much later, as with cancer? Such questions, Slovic says, “reflect values that are sometimes left out of the experts’ calculations.”
Security theater, from this perspective, is an attempt to convey a message: “We are doing everything possible to protect you.”
