Using abbreviations while texting can make you seem insincere, according to a new research study. Participants who used text abbreviations were perceived as putting in less effort, resulting in fewer responses. The study involved eight experiments with over 5,300 participants. Researchers found that texters who used abbreviations received shorter and fewer responses. The research showed that texting with abbreviations could contribute to feelings of loneliness as people receive less frequent or positive replies to their messages.
