Ever order a drink, and feel cheated on the pour? Before you trouble the waiter, take a closer look at the size of your glass. “People will generally think there being less in larger containers, than in smaller ones.” Says Theresa Marteau, a behavioral scientist at the University of Cambridge, in England.

She and her workmates had analyzed（分析）how larger amounts—and larger plates—trick us into eating more food. And they wondered: could the same be true for alcohol?

So the researchers convinced the employees at a local bar to run an experiment: every two weeks, for four months, they’d change the bars wine glasses from the standard 300 milliliter size, to either slightly larger—370 milliliters, or slightly smaller—250 milliliters. They saw how the size of the glass affected customers’ drinking habits, even though the pour, the amount of alcoholic drinks, was unchanged.

It turned out that serving wine in smaller glasses had no measurable effect. But the large glasses increased wine sales 10 percent-even after controlling for day of the week, temperature, holidays and so on. The reason? “When the wine, the same amount, is being served in a larger glass, people are probably thinking they’ve got less in there.” Which, she says, means they might drink more, believing they haven’t hit their nightly limit. Or, they might just feel less satisfied with the pour, and buy another round. The study appears in the journal BMC Public Health.

Marteau says that, if later studies confirm this effect, public health officials might consider directing a certain average glass size. “Stating clearly the largest size in which wine can be sold could be a measure to reduce the overconsumption（过度消耗）of alcohol that seems to be shown by the glass size.” Until that happens, the bar in the study now always serves its wine in the larger glasses.
