>they care for what they think is the truth, and what support their opinions.
I'd take this one step further and say that the majority of people don't have consistent opinions about what the truth is, they only care for receiving the informational stimuli they've been conditioned to perceive as pleasant.
UBI is therefore an experiment in nomenclature. The reality of governments giving money over long periods of time to citizens whose labor is not market-competitive is nothing new. What's being tested is how it's branded: "welfare, benefits" is a humanistic, "socialist" way of branding it while "universal, basic, income" are words more in line with the rationalistic, "neoliberal" memeplex.
