PRIVACY IS JUST A MEDIUM FOR SIN:

How the Illusion of Being Observed Can Make You a Better Person: Even a poster with eyes on it changes how people behave (Sander van der Linden, May 3, 2011, Scientific American)

I think Thomas Jefferson was on a similar train of thought when he wrote, “Whenever you do a thing, act as if all the world were watching.” I always found this to be a particularly interesting quote, as it reminds us of the fact that we tend to be on our best behavior when we know that we are being observed. While this may seem obvious, new research points to something far less obvious: it doesn’t take a fellow human being to make us feel “as if the world were watching,” not even another living organism. All it takes is an image of a pair of human eyes.

A group of scientists at Newcastle University, headed by Melissa Bateson and Daniel Nettle of the Center for Behavior and Evolution, conducted a field experiment demonstrating that merely hanging up posters of staring human eyes is enough to significantly change people’s behavior. Over the course of 32 days, the scientists spent many hours recording customer’s “littering behavior” in their university’s main cafeteria, counting the number of people that cleaned up after themselves after they had finished their meals. In their study, the researchers determined the effect of the eyes on individual behavior by controlling for several conditions (e.g. posters with a corresponding verbal text, without any text, male versus female faces, posters of something unrelated like flowers, etc). The posters were hung at eye-level and every day the location of each poster was randomly determined. The researchers found that during periods when the posters of eyes, instead of flowers, overlooked the diners, twice as many people cleaned up after themselves

In fact, this research builds on a long tradition of psychologists being interested in explaining and stimulating human cooperation in matters of the collective. In technical terms, we often speak of a “social dilemma,” that is, a situation where personal interests are at odds with that of the collective. (For example, it would be easier for me to throw my trash on the ground, but if everyone thought that way, we would all be stuck with a huge pile of waste.) Robyn Dawes and colleagues showed in the 70’s that the presence of other people in the room tends to have a positive effect on people’s decision-making when faced with a social dilemma. Yet, it wasn’t until a few years ago that Terence Burnham and Brian Hare published an article in Human Nature that showed people make more cooperative choices in economic computer games when they are “watched” on the screen by a robot with human-like eyes. Somewhat baffled, a number of researchers subsequently conducted a set of experiments that confirmed these initial findings.

While philosophers have fretted about it, one of the great strengths of democracy is the weight of social conformity it brings to bear on the citizenry.
