One study indicates that during an argument (in any setting), using profanity can lead to higher effectiveness and persuasion. If you’re trying to be seen as passionate and firm in a stance, using swear words can help your agenda.
By swearing, we not only communicate the meaning of a sentence, but also our emotional response to the meaning — our emotional reaction to something. It also allows us to express anger, disgust or pain, or indicate to someone that they need to back off, without having to resort to physical violence.
Along with this, studies show that those who curse have higher levels of integrity and can, in turn, be much more honest people. According to research, those who use profanity tend to lie less, as tested on a lie detector exam. In terms of your mood, researchers also say that letting out a few bad words every now and again can actually release endorphins, like exercising, and can overall improve your mood. There’s nothing like letting out a few F-bombs when you’re having a really bad day, right?
