You're in the middle of a texting conversation when the other person suddenly stops for a long pause before responding. What does it mean? Maybe they got a call or got distracted by something else, or their thumbs needed a break. But it's also possible they're taking the time to cook up a lie.
Researchers from Brigham Young University asked more than 100 college students to respond to 30 questions each that were generated by a computer and texted to the participants. In half of their responses, the students were asked to lie. The researchers found that when the students lied, it took them 10% longer to send the text message and they made more edits than usual.
When communicating with someone in person, most people look for behaviors that they feel are indicators of dishonesty, like not being able to look people in the eye or moving nervously. Spotting such signals is hard to do when someone is on the other end of a string of text messages. But the new research suggests that some patterns, such as the delay in texting, could become a sign for detecting lies in such communications. The researchers say their findings raise questions about how the validity of communications on social media might be interpreted on matters of security and personal safety.
