Like, it's linguistics
New research shows that Valley Girls are just, like, really really thoughtful.
A new study published in the Journal of Language and Social Psychology shows that those who used "filler speech" ("like," "um," "uh," "you know") tend to be more considerate. "When having conversations with listeners, conscientious people use discourse markers, such as 'I mean' and 'you know,' to imply their desire to share or rephrase opinions to recipients," the study's authors wrote.
The researchers also found that the discourse markers were most common among women and younger participants, which shows that filler word use could be a potential personality and social marker.
