> Interesting how political parties are for or against this pilot project before the results are known. What happened to gathering evidence first and then making up one's mind?

Would you run a pilot of every idea? At the level of a country?

Paying everyone in Wales £ 1 is a big endeavor, let alone a value that's meaningful and on a monthly basis, so it's not as if a pilot comes at no cost. You could certainly form an opinion from experiments in other places, or economic thought expirements or from wherever it is politicians pull most of their thoughts.
