Yeah, I have looked through those. I remember personally as the Ontario one was going through. Even then it already had a huge backlash, and people were opposing to it because of "fairness and etc.". Unfortunately none of those tests can help with understanding what would happen to inflation, jobs that nobody wants to do, life satisfaction of middle class, and everything else, to be honest. And I also understand that trying it out on any large populace is incredibly expensive.
It’s of course not the same as UBI, but something close to it - basically everyone is entitled to it and while it’s really not a lot you can survive off it.
Probably not the scale you imagine but there have been plenty of tests.
