Seems like the grandaddy of developmental psychology over-estimated the competance of everyone over eight years old. At about this age we learn about conservation of volume, in particular that a tall thin glass doesn’t necessarily have more in it than a short fat one.. except we often forget when drinks are involved.
Short glasses more likely to lead to over-indulgence
Shape of glass and amount of alcohol poured: Comparative study of effect of practice and concentration; BMJ Volume 331 pp 1512-4People pour 20-30% more alcohol into short, wide glasses than into tall, narrow ones of the same volume, but they wrongly believe that tall glasses hold more, finds a study in this week’s BMJ.
Even professional bartenders pour more into short, wide “tumblers” than into “highball” glasses, suggesting that experience of pouring alcohol has little effect.
make mine a short!
