The results were that the one with unconditional payments had "better mental health".
Apparently they used a "validated five-item mental health screening instrument that identifies people at risk of mood and anxiety disorders", but realistically how much of this is just people prefer money with no strings attached. Seems pretty obvious. I'm sure a lot of things are linked to "poor mental health" like having to go to work, doing chores and basic maintenance to stay alive. Don't really know is this kind of observation has broader implications
