12. You can make your own beleifs

But you can't make your own facts.

Hey, I'm a machinist - we routinely measure to .001/inch - that's half a hair! You can beleive all you want - but a pin that measures .752 isn't going to slip-fit into a 3/4" hole. .752 - .750 = .002 interference. Steel to steel, that'll take a small sledgehammer or a big-ass press to put together, beleif or not. Heat or cold can be used, as well - but when the temperatures equalise, it ain't movin'. Or, you can turn/file/polish the pin down a bit - but that is changing the facts!

The trouble is, the folks who watch Fucks News take beleifs (or conjecture, or outright friggin' lies) as fact - and it just don't work!

Or, as a friend of mine put it - the pieces of a jigsaw puzzle aren't "trim - to - fit"!

My Dad was a precision inspector by trade - he saw his job as establishing the facts (to .00005, in a temperature - controlled room, with measurements traceable to NIST). He was fond of quoting Sen. Sam Ervin "Once you have the facts, the law will take care of itself."
