Proper punctuation is a useful and necessary tool. But if you use it in a text, people will think you’re less trustworthy. At least that’s what a new study from researchers at Binghamton University is claiming.

According to the study, people who end their texts with a period are perceived as less sincere than those who don’t bother.

“When the exchanges appeared as text messages, the responses that ended with a period were rated as less sincere than those that did not end with a period,” the study’s abstract stated. “Punctuation is one cue used by senders, and understood by receivers, to convey pragmatic and social information.”

However, no such perception was found for people who use proper punctuation in a written message.
