Many people attempt to diet, but a few also attempt to cut down on their drinking habit at some point in life. However, majority fail, often blaming it on a lack of motivation.
What we found here is an interesting factor at work, which could help reduce the intake of alcohol.
In an experiment, Brian Wansink and Koert van Ittersum from Cornell University asked students to pour a single shot of whiskey from a full bottle into a glass. Those given a short, wide glass poured, on average, 30% larger shots than those given a taller, narrower glass. This happened because we use the depth of the liquid as an indication of the amount of liquid in the glass, not noticing that one glass was far wider than the other. These researchers then repeated the experiment with experienced bartenders and discovered that they poured, on average, 20% larger shots into the short, wide glass.
So if you want to reduce your drinking, stay away from short, wide glasses, and stick to tall, narrow ones. But of course, if you want to get drunk faster or get someone else drunk faster, use short, wide glasses.
