As I remember it, there were four kinds of UBI trials:

- Low UBI, short term

- Low UBI, long term

- High UBI, short term

- High UBI, long term

Both low UBI kinds did little except provide a little better food/medical security for poor folks.

High UBI short term mostly only led to people either saving or spending the money immediately.

High UBI long term was the only one where the effect I was talking about showed up. Most people carried on as they did, some reduced hours, there was an increase in people switching jobs, and an increasing in people leaving work to get a degree.

I also remember the difference between the first three kinds and the last kind led to confusion between UBI trials.

Admittedly I haven't looked in a few years, so I'll have to check again.
