Looking to snag a promotion? Taking your boss out for drinks may not be the best idea then. Researchers at the Universities of Michigan and Pennsylvania have found that even though people may think they look intelligent while holding or ordering a drink, quite the opposite is true. It changes their colleagues’ assumption of their brain power. What’s more, their arguments are viewed as less persuasive and they seem less hireable by a prospective employer. While this research has garnered criticism from certain beer- loving sections, we’d suggest you restrict your frolicking to weekends only.
