Business Insider compiled a list of things that can make you look DUMB at work. And they're all backed by science...
Here's the top four:
1. Emojis in your emails: A series of studies last year found they can make you seem less competent. Most people still think they're just too informal for work emails.
2. Inappropriate jokes: A study in 2016 found that telling a GOOD joke is one of the BEST ways to seem smart and competent at work, but jokes that involve swearing or inappropriate topics can have the opposite effect.
3. Cussing: A Career Builder survey in 2012 found about half of us DO swear at work sometimes. The same survey also found over 50% of bosses think swearing makes employees seem dumber.
4. Never asking for advice: A Harvard Business School study found most of us think asking for advice would make us seem less capable, but we have the opposite opinion when other people do it.
