There’s no way to test UBI without implementing it fully. Any experiment that gives people a no-strings-attached stipend isn’t accounting for the fact that the money has a negligible impact on the economy and produces no meaningful change in the workforce. Plus, all of these experiments are time-bound. Participants know the payments will stop.

I also get the feeling that such experiments just prove that giving people money makes them happier. But there’s nothing to account for the fact that prices in the market haven’t changed, the tax structure hasn’t changed, and no goods or services experienced any shortages.
