The Anger Trigger in a Text: Why the Single Letter “K” Stings in Thai Digital Culture
A new study reveals that replying with a single letter, “K,” sparks the strongest negative emotions in digital conversations, more than being left on read or receiving curt responses like “sure” or “fine.” Published in the Journal of Mobile Communication and highlighted in a Times of India feature, the finding shows how ultra-short messages can carry surprising emotional weight.
In Thailand’s fast-growing digital scene, where personal, professional, and cross-cultural chats are routine, a blunt “K” extends beyond simple acknowledgment. The study surveyed 1,500 adults aged 18–45, using surveys, sentiment analysis, and biometric data such as heart rate. Results consistently label “K” as cold and dismissive, often read as passive-aggressive or abrupt. Both men and women felt the impact, with women showing a slightly higher sensitivity to its effects.
