People Who Swear More are Shown to Be More Honest, According to Research
Updated: Jun 3, 2025
Swearing might not be the most polished habit, but science says it could be a sign of something surprisingly positive: honesty. According to a study published in the journal Social Psychological and Personality Science, researchers found a strong connection between frequent swearing and higher levels of integrity. In other words, people who curse more tend to lie less.
What swearing really signals
Swearing is often seen as inappropriate, but it’s also incredibly expressive. It bypasses social filters and delivers raw emotion, something that tends to align with truth-telling.
The study, which involved over 270 participants and data from 75,000 Facebook users, found that people who used more profanity were less likely to engage in deception and more likely to show genuine self-expression.
Lead researcher Dr. David Stillwell noted, “When someone swears, it’s often a way of being honest about how they feel.”
Honesty over politeness
While excessive swearing in professional settings may not be ideal, occasional profanity in conversations could indicate authenticity, not aggression. In fact, swearing may serve a social function, letting others know they’re getting the real you.
Of course, context matters. But the next time someone drops a well-timed curse word, it might just mean they’re being straight with you.
Final thoughts
Swearing isn’t just about shock value. It’s often about sincerity. So if you tend to let a few words fly now and then, science says you're probably just keeping it real.
