The 5 year period of this study will be a significant limitation. An important part of a guaranteed basic income is the <i>guarantee</i>. If I was in a programme that I knew would end after 5 years, I would be very concerned with things like maintaining my employability when the 5 years are up. In other words, while I would love to dedicate 5 years to non-commercial art and science, my option to do this is severely curtailed if I&#x27;m expected to re-enter the same old job market with 5 years less experience than my peers.<p>But overall I am thoroughly supportive of doing the experiment anyway, as we do desperately need more data on this important concept.
