It does not go door to door.

It does not perform.

It has no urgency, because it does not need any — it is going to be true whether anyone believes it or not, and so it feels no compulsion to hurry.

A lie is the opposite.

A lie is frantic and energetic and social; it has to move, and move fast, and get itself established in as many minds as possible before the slow truth ever arrives, because a lie’s only hope of survival is to become the accepted version before anyone thinks to check.

And so, in the race between them, the lie almost always gets a head start, because the lie is running and the truth is standing still.
