My advice would be not to worry about it. I don’t know how old you are but that “I’m smarter than you so that makes me better than you.” attitude gets unpopular quickly outside of high school and college. No one likes a smug asshole who has to be right all the time. And they won’t be right all the time anyway, no one is a genius expert in everything, they might know math or physics or medicine or whatever, but that doesn’t mean shit in fields they know nothing about. I would recommend not wasting time with them if possible. If you have to work with them or something, try to keep it in a professional context, when they rant about how much Rick and Morty they watch or whatever, just tell them you need to focus on the job at hand. Make it clear that you don’t want to hear them brag about how much smarter they are than everyone else, in a very detached and professional way.
