Social filter idea.

What about a social filter where people are tested in precise conditions, if when left in nature with a bottle of water, for one day, and they're told they shouldn't drink the water, they resist or indulge in drinking the water?

And then you earn that badge, verified blockchain or whatever, visible on your social media.

How many online discussions would be unwasted time? How many petty, shallow conversations? What if you self-segregate to live around people that could resist the water?

There could be bi-annual tests like this.
The concrete test is not so important really. Could be done with a cookie (these days it's probably a good cut-off point anyway since otherwise you end up hanging up with 3 people :P )

I'm not saying I won't drink the water, idk. But it's an interesting filter
