If you’re like most people, you’ve probably unsent a message before – whether it was because you caught a typo, realized you were sending it to the wrong person, or simply regretted what you said. But have you ever wondered why you unsent that message in the first place? According to new research, there are four main reasons why people unsend messages: to avoid awkwardness, to save face, to prevent further hurt feelings, and to protect a relationship. So next time you hit the unsend button, think about why you’re doing it – and whether it’s really the best decision for yourself and the person you’re communicating with.
