Indeed. One of the main criticisms of both Canadian major experiments with UBI (Manitoba in the 70s, and Ontario in the last few years) was that while they paid regularly, both programs were relatively short-lived -- a few years. This doesn't appropriately model the incentives and behaviours people would likely engage in if they knew with reliability the program would still be paying them in ten or more years. It wouldn't capture either negatives like people leaving the workforce permanently, or positives like going back for a four year degree they couldn't otherwise afford. Participants likely treated it as a one-time windfall (if over a couple years).
