People will think you're a jerk if you end texts with a period, scientific study finds

No one likes receiving a text with a period attached to the end, according to a new scientific study. Sure, it might be grammatically correct but people really will think you're a jerk. The study, conducted by Celia Klin and her team of researchers at the Binghamton University, found that text messages that end with a period are perceived to be less sincere. To conduct their research, Clin and her team recruited 126 Binghamton undergraduates to read a series of 16 messaging exchanges. Based on the participants' responses, the texts that ended with a period were seen as being much more insincere than the texts that had no punctuation at the end. Moreover, texts that ended with an exclamation came off as being more, rather than less, sincere.
