Here is a more in depth report on the psychological effects. Those effects are non-trivial.
Even that doesn't look that terrible for an early attempt.
"Only two of the men adapted well to the mission. Of the other four, there was at least one major reason for concern, where we would ask, should we really send someone like this on a long mission," Basner said.
So, you have two well-adapted, three with issues, and one major problem. So, 1-in-3 did fine (which amusingly, is also roughly the early success rate of the rockets themselves). And that's before pointing out that the problems are attributed as much to *boredom* as isolation.
I read that, and I see useful research - they need useful things to do on the inbound and outbound trips. (I mean, if there's nothing to do - literally, nothing to do - wouldn't you sleep a bit more?)
Psychology being important is a good point as well - but that's a slightly different issue from "should we send one-way people". The problem is that some people just aren't suited to long trips with nothing to do. They'd probably have the same response if snowed in.
