I see this old picture- taken at one of my birthday party's growing up- and feel 99.99% certain there were a lot of "like(s)" and "you know(s)" being thrown around...

According to a new study, people who use filler words like “um,” “like,” “you know,”  and “I mean,” are actually more thoughtful.

This, of course, flies in the face of the idea that filler words like this are used by airheads.

Researchers found that smart people in leadership roles use these words all the time – and the words tell the listener that the speaker wants to either pause for a moment to get his or her thoughts together or prevent the listener from starting to talk.

And, using these words in everyday speech is part of “the processing of complex thoughts.”

So, like, don’t feel embarassed if you use filler words. You, um, still might be totally smart, you know?
