Study: "Grammar Police" behavior linked to personality

ANN ARBOR, MICH. — It’s more than likely you know someone nicknamed “the grammar police,” someone who reads an e–mail or a Facebook post and tries to catch all the little typos.

According to linguistics experts at the University of Michigan, that behavior is partly because of certain personality traits.

According to a recent U of M study,  extroverted people are likely to overlook typos and grammatical errors that would cause introverted people to judge the person who makes the errors.

The study reports that less agreeable people are more sensitive to grammatical errors, while more conscientious and less open people are sensitive to typos.
