Some rules exist because they had to be implemented. Like the speed limit or legal drinking age. Meanwhile, some rules have backfired big time and made the people who implemented them regret their decision. Check out our previous post about such instances right here.
But there are rules that need no introduction. They’re not documented in books nor authorized by law, and still, they govern our daily lives. This simple “common sense” is also known as “unwritten rules” and they refer to common behavioral constraints we all take for granted.
Things like not swiping sideways if someone shows a picture on their phone, or never making fun of someone else’s laugh. Sounds random, but people swear by it! Scroll down below for more unspoken rules listed by people online.

Always start with the question "how might I be wrong?"
Everyone can figure out a reason to believe they're correct, but if you look for reasons you are wrong first you will make fewer horrific assertions and mistakes.
"How might I be wrong" is the core question of science and the start of all wisdom.
