Does ordering beer in public vs. in private make a difference?
As a part of an experiment [1], two professors borrowed a brewery and pretended to be waiters. This allowed them to hand-out surveys and take notes of what people ordered; they paid the brewery to give customers free samples. People ordered either publicly, one after another by stating what they wanted, or privately, by writing down the order. Fifty tables each were served in the two ways of ordering.
Which way of ordering resulted in the highest variety in the types of beer ordered?
