As a big fan of UBI this infuriates me. We can't test it unless we do it nationwide. In business school they hammer into you that "cashflow is the lifeblood of the business". It stands to reason that the same goes for the economy so why are we messing about with pointless 120 person trials. That isn't testing the right aspect of the system. We need to test it's systemic impact not the impact it has on individuals.
