Don’t hold a beer
I know, I know, how dare I even suggest you don’t walk around palming several beers at a time. But, sadly, people do dumb things after a few drinks, which is why even holding a beer is making your look less intelligent. “People who hold an alcoholic beverage are perceived to be less intelligent than those who do not, a mistake we term the imbibing idiot bias.”
So maybe pick your spots wisely. Hold a beer when everybody else has a drink in their hand as well.
