Common knowledge

Many people think that there is quite a store of common knowledge amongst the residents of Earth, but in fact, there are many people who occupy the planet who are deliberately ignorant. Thus, just because someone assumes something is "common knowledge," they may be incorrect.

There is, in fact, only one piece of actual common knowledge: People lie. If you did not know this previously, you were ignorant. Now you know. It is thus now, more than ever, common knowledge. Thank you for playing.
