"A group of MIT students tasted two different beers, and then choose to get a free pint of one of the brews. Brew A was Budweiser. Brew B was Budweiser, plus 2 drops of balsamic vinegar per ounce. When students were not told about the nature of the beers, they overwhelmingly chose the balsamic beer. When students were told about the true nature of the beers, they overwhelmingly chose the Budweiser."
