In an era dominated by instant messaging, a 2023 study published in the Journal of Mobile Communication has identified the single-letter response “K” as the most negatively received message in digital conversations.
According to researchers, this brief reply was ranked more upsetting than being left on read or receiving a dry “sure,” underscoring the emotional nuances embedded in everyday texting.
Despite its brevity, the letter can evoke strong reactions, suggesting tension, dismissal, or frustration. Researchers emphasize that such micro-messages can carry disproportionate emotional weight, especially in a communication landscape where tone and body language are absent.
Experts suggest that the emotional impact of short responses like “K” reflects a broader shift in how digital interactions are experienced and interpreted.
As messaging becomes increasingly central to both personal and professional relationships, even the smallest cues can have significant effects on trust, clarity, and connection.
