So you're basing this on your feelings rather than the available data.
To repeat the point you're replying to - a UBI study that examines human behavior from a set of people who are only guaranteed to be given some livable amount of income for a short period, and not for their entire lives, is completely useless. It isn't actually studying UBI. It's studying "what do people do if I give them $20k or so over a few installments?".
Very boring thing to study. Honestly a waste of time and resources to even bother conducting such a study, the results can be put directly in the rubbish bin.
