You can also donate to them. They provide direct cash transfers to the worlds’s poorest communities, as well as ongoing research into the effects of things like UBI.

I like that they included the mental health component. Long-term steady payments are best for mental health and can fairly easily be converted into lump sums by pooling payments and rotating payouts with others receiving UBI.

This is important because lump sums are most likely to spur entrepreneurship since they have the capital to invest, immediately, in a new venture. (But the unpredictability of starting a new business also means they are less happy.)

It’s nice having some hard data to support how we should go about UBI. Now we just need to revert taxation to what it was like a century ago to pay for it.
