> You can argue that the only way to perform a completely accurate UBI experiment would be to run it for at least 60-80 years for everyone. You could get decent results in less than 60-80 years by granting each participant a fully-funded fixed annuity guaranteeing them a specific income for the remainder of their lives independent of the continuation of the study. Of course, that would raise the cost of the study to something approaching a real (non-universal) BI program.
