Subtle eye images alone curb cheating even with no real observer present

Evidence

Are people therefore less likely to cheat the system when they sense that someone is watching them? In one field study, researchers placed a self-service coffee stand in the hallway of a university building and an “honesty box.” Passersby could avail themselves of some coffee, and leave money in the box. On some randomly assigned weeks, a poster with watchful human eyes was hanging above the stand; on other days, the poster showed various types of flowers. Despite the fact that consumption rates were similar across the two conditions, significantly more money was left on weeks when the poster with eyes was hanging on the wall. On average, people left 2.76 times as much money in the weeks with eyes. The feeling of being watched, even as subtle as posters of eyes on a wall, curbed cheating when no one was present to make sure the system works. Eyes on the wall did the job. — Norenzayan, Ara, Big gods - how religion transformed…, 92

• ADDENDUM: Directly supports the analytical bridge in the reader’s stated purpose: the fumi-e forces public, observed apostasy precisely because the perceived gaze—even a schematic or symbolic one (the Emperor’s authority, the community’s eyes)—suppresses nonconforming moral behavior. The Coffee stand eye poster is the cleanest empirical demonstration that watchfulness cues work psychologically, which is what a priest forced to trample understands his performance to trigger in witnesses.
