I assume it is part of a long-term effort to move governments towards a Basic Income. But a more useful campaign to make BI a reality is not to juice the early experiments to make them look more appealing. A much better strategy is to do good research and find which aspects of BI would really work and which aspects don't actually hold up.
The main problem around BI is there's a massive lack of data available for how people actually behave. All of the conversations around BI end up as circles of speculation around how people would react and others saying: "boy, it sure would be nice to have some real data around the topic".
So, to answer the first question: the desired outcome is a better understanding of how people in the real world react to a BI, and a better understanding of which BI mechanisms work well and which BI mechanisms fall apart under real-world conditions.
Preventing a new october revolution in its infancy seems to be high on the list.
