To prove their findings, they also took to Facebook (where everyone reveals the most sincere and candid version of themselves) and compared how 75,000 users posted profanity; people who cursed more were -- you guessed it -- found to be telling the truth about how shitty (or fan-fucking-tastic) their lives were.
Obviously there's no way to tell 100% if people are being honest on social media. The researchers assessed each post using language patterns that are associated with honesty, such as using "I" and "me" pronouns more often.
"The relationship between profanity and dishonesty is a tricky one. Swearing is often inappropriate, but it can also be evidence that someone is telling you their honest opinion," said Dr. David Stillwell, a co-author on the study, according to ScienceDaily.
