Dan Piepenbring: “Writers like to emphasize the psychology in their work, their strenuous labor toward depth and verisimilitude; they’re less inclined to talk about how few decent synonyms exist for ‘good.’ The stats speak a cold truth: there are dozens of prosaic choices behind every artful sentence. […] Even in great books one word follows another, all of them slaves to grammar, sequence, and probability.”
People who swear tend to be more honest than those who don’t. A 2016 study found “a consistent positive relationship between profanity and honesty; profanity was associated with less lying and deception at the individual level, and with higher integrity at the society level.”
When it comes to swearing, as with everything else, grammar matters.
