Earlier quoted context omitted.
Sounds like the participants knew the study was temporary and invested the money in a job they knew they’d need after the study.
Exactly. With a permanent UBI in place you can throw all these studies out the window.
I understand it's much more stressful than permanent guaranteed UBI, but it's truer to the real intent of UBI (which I believe is reducing the friction when deciding to try new job or state or whatever in a pursuit of self-actualization).
