A new study from Iowa State and Cornell revealed that individuals who use a narrow glass and pour wine while keeping the glass on the table drank less, compared to those who used a wide glass and poured wine while holding the glass, Nature World News reported.
According to the researchers, it all has to do with the drinker’s perceptions of quantity.
“People have trouble assessing volumes,” said Laura Smarandescu, an assistant professor of marketing at Iowa State. “They tend to focus more on the vertical than the horizontal measures. That’s why people tend to drink less when they drink from a narrow glass, because they think they’re drinking more.”
In reality then, the glass is neither half empty nor half full. It’s simply time to refill your drink.
(The engineer will tell you the glass is exactly twice the size it needs to be, but who the hell do they think they’re kidding?)
