I'm sure they're well aware that a one year test won't answer a lot of questions. But it will answer some, and it will probably help them set up a better experiment for the future.

And the same criticism could be levelled at a 5 year experiment. I think that eventually they're going to have to do a lifelong experiment, buying annuities from a reputable insurance company for the recipients. That's going to be expensive, so make sure you have the experiment set up right before you do it.
