Everyone who's ever tapped a touchscreen knows that putting a period at the end of a one-word text message, like "OK." or "Yeah." or "Fine," is a surefire way to come off as complete asshat -- whether it's intentional or not. While some may argue it's a matter of being concise and using good grammar, new research has now confirmed that the punctuation actually does come off as, well, pointed as you suspected. Cool.
In a new study published in the journal Computers in Human Behavior, researchers at Binghamton University found that ending text messages with periods will likely result in the recipients perceiving you as insincere, according to a report by The Washington Post.
The team of experts, led by associate professor of psychology Celia Klin, surveyed 126 undergraduate students at the school after reading a series of 16 experimental conversations via text message or handwritten notes. The exchanges involved a statement and invitation from a sender such as "Dave gave me his extra tickets. Wanna come?" followed by an affirmative one-word response from the receiver (like Sure, Yeah, or Yup), with one version ending with a period and one ending with no punctuation. In the end, the students rated messages ending with a period as less sincere.
