The affirmative gesture that was originally meant to signal “OK” in certain cultures can mean anything but in digital communication. This reaction may be perceived as passive-aggressive, disinterested or sarcastic in a text, depending on how it’s used in an online conversation.
One reason for this ongoing confusion may be generational differences between people who see a thumbs-up emoji as passive-aggressive and those who see it as an innocuous “liking” reaction built into platforms like Facebook and Instagram. One 2025 survey found that nearly 4 in 10 workers –– 38% –– use the “thumbs up” reaction to signal agreement, but a growing number of younger colleagues say it can feel dismissive or sarcastic.
What makes the thumbs-up reaction even more ambiguous is when it’s presented without any more reassuring context. In a text, a one-word “OK” reply can feel hostile, because brief answers imply a lack of effort, linguistics experts say. This is also why answering only “sure” to your friend’s request for your time can make them feel unsure if you actually want to attend their party.
“This is especially true when the thumbs-up isn’t proportional to the message you’re responding to,” Leighton said. “If I just sent you a long heartfelt paragraph about my feelings, you’re going to have to do better than just give me a thumbs-up.”
“Rare is the person who’s genuinely going out of their way to be rude,” he said. “In the end, they’re just little pictures and it’s best to [not] read too much into them.”
