curious what mine is

Everyone has their own bit of crazy. Key to relationships. Compatibility or tolerance to the crazy.

Most of the world is seemingly reasonable and still they use and work for money that’s being inflated away at a rate of 7-10% per year.

If it is a scientist and the belief is in their field, then it's a good thing. Let Linus Pauling reach for crazy Vitamin C, or physicists believe in crazy E8 or whatever.

But yeah, outside of that it happens all over the place.

Most people are not trying to carefully cultivate the truth in the gardens of their mind. They have competing interests, especially group-membership interests which evolved for very important reasons (not finding yourself dead because people near you thought you were a traitor).

One mans insanity is another mans Jesus.

Whats yours

it's the chaos theory, man. Humans will always fix on something unexpected. It's a sign our brains are working properly.

"How do you get equal peers to agree on a fact by themselves?"

1. They're not equal peers. Competition yields the result.

2. They can't do it by themselves. Shared belief in an omniscient, omnipresent deity yields the resilt.

3. Bitcoin

We don't like to compete, and we never had a 3rd option before. so I'm pretty sure your answer lies somewhere in option 2.
