Can you provide any links that show that every time it’s tried, it fails?

Skimming this list, there seems to be one really marked failure, in Finland, but that’s disputed I read also.
Can you list more failures?
This link says very explicitly that it did show people were discouraged from working, making the experiment obviously a failure.
> Among all the people, only two key groups were found to be discouraged from working by the Mincome project – new mothers and teenaged boys, who, instead of entering the workforce at an early age, decided to study until grade 12, increasing the proportion of students who graduate high school.
