Next time you're ordering drinks with your friends, you might want to step up and order first. It turns out that when everyone in a group places their beer order out loud, it screws with everyone's decision making process. If you wanted a lager and then your friend goes ahead and orders a lager, you might just end up ordering an IPA just so you look a little more unique.
This phenomenon shows up in a study that explores just that: how do people's beer orders change when they're ordering in a group context versus when they're ordering alone? It turns out, they change pretty significantly. One group of participants in the study wrote their beer orders down on a piece of paper that others didn't see. Another group all went around and placed their orders aloud. The participants were given the choice of one of four beers: the Copperline Amber Ale, the Franklin Street Lager, the IPA, and the Summer Wheat.
