This is a huge issue that is very hard to solve at this point. The obvious solution, not telling people about the experiment, is out. It reinforces the skeptics who think of this as a way for YC to brand itself more philanthropically, because from a research perspective it's just expensive, grandiose hogwash. Edit to say that I too support UBI, and actually helped pass a resolution at my Congressional District's Democratic Party convention in favor of UBI.
