People Good At Swearing Have This Major Advantage - larger vocabulary

I knew a guy with aphasia from a stroke bowling group who could swear up a storm. I don't think this finding necessarily applies to him.

People who know more swear words also have stronger verbal abilities, a new study finds.
Knowing how to swear, then, is not a sign of a poor vocabulary — in fact it signals a better vocabulary.

The study tested how many different swear words people could think of in 60 seconds.

One caveat: this study does not test or suggest that using lots of swear words is a sign of a larger vocabulary.
It only tested (and found) that knowing them is linked to a larger vocabulary.
The new study was published in the journal Language Sciences (Jay & Jay, 2015).
