“There was no social pathology—none,” Dwight Heath said. “No arguments, no disputes, no sexual aggression, no verbal aggression. There was pleasant conversation or silence.” He went on: “The drinking didn’t interfere with work.…It didn’t bring in the police. And there was no alcoholism either.”
Heath wrote up his findings in a now-famous article for the Quarterly Journal of Studies on Alcohol. In the years that followed, countless other anthropologists chimed in to report the same thing. Alcohol sometimes led people to raise their voices and fight and say things they would otherwise regret. But a lot of other times, it didn’t. The Aztec called pulque—the traditional alcoholic beverage of central Mexico—“four hundred rabbits” because of the seemingly infinite variety of behaviors it could create. Anthropologist Mac Marshall traveled to the South Pacific island of Truk and found that, for young men there, drunkenness created aggression and mayhem. But when the islanders reached their mid-thirties, it had the opposite effect.
In Oaxaca, Mexico, the Mixe Indians were known to engage in wild fistfights when drunk. But when anthropologist Ralph Beals started watching the fights, they didn’t seem out of control at all. They seemed as though they all followed the same script:
Although I probably saw several hundred fights, I saw no weapon used, although nearly all men carried machetes and many carried rifles. Most fights start with a drunken quarrel. When the pitch of voices reaches a certain point, everyone expects a fight. The men hold out their weapons to the onlookers, and then begin to fight with their fists, swinging wildly until one falls down, [at which point] the victor helps his opponent to his feet and usually they embrace each other.
None of this makes sense. Alcohol is a powerful drug. It disinhibits. It breaks down the set of constraints that hold our behavior in check. That’s why it doesn’t seem surprising that drunkenness is so overwhelmingly linked with violence, car accidents, and sexual assault.
But if the Camba’s drinking bouts had so few social side effects, and if the Mixe Indians of Mexico seem to be following a script even during their drunken brawls, then our perception of alcohol as a disinhibiting agent can’t be right. It must be something else. Dwight and Anna Heath’s experience in Bolivia set in motion a complete rethinking of our understanding of intoxication. Many of those who study alcohol no longer consider it an agent of disinhibition. They think of it as an agent of myopia.

The myopia theory was first suggested by psychologists Claude Steele and Robert Josephs, and what they meant by myopia is that alcohol’s principal effect is to narrow our emotional and mental fields of vision. It creates, in their words, “a state of shortsightedness in which superficially understood, immediate aspects of experience have a disproportionate influence on behavior and emotion.” Alcohol makes the thing in the foreground even more salient and the thing in the background less significant. It makes short-term considerations loom large, and more cognitively demanding, longer-term considerations fade away.
Here’s an example. Lots of people drink when they are feeling down because they think it will chase their troubles away. That’s inhibition-thinking: alcohol will unlock my good mood. But that’s plainly not what happens. Sometimes alcohol cheers us up. But at other times, when an anxious person drinks they just get more anxious. Myopia theory has an answer to that puzzle: it depends on what the anxious, drunk person is doing. If he’s at a football game surrounded by rabid fans, the excitement and drama going on around him will temporarily crowd out his pressing worldly concerns. The game is front and center. His worries are not. But if the same man is in a quiet corner of a bar, drinking alone, he will get more depressed. Now there’s nothing to distract him. Drinking puts you at the mercy of your environment. It crowds out everything except the most immediate experiences.2
Here’s another example. One of the central observations of myopia theory is that drunkenness has its greatest effect in situations of “high conflict”—where there are two sets of considerations, one near and one far, that are in opposition. So, suppose that you are a successful professional comedian. The world thinks you are very funny. You think you are very funny. If you get drunk, you don’t think of yourself as even funnier. There’s no conflict over your hilariousness that alcohol can resolve. But suppose you think you are very funny and the world generally doesn’t.
