Am I dumb or is this not saying what anyone here thinks it's saying?
Basically, it's not just that 50% have no regret / good satisfaction, but in fact that for this 50% there is not even a hint of dissatisfaction or regret. That's the news. The median isn't 4 or 1, it's 5. So 50% of people are absolute ends of the scale.
But this abstract legit says NOTHING about the tail. So it could actually be that 20% of people have complete regret. Median without average is not that convincing in a case like this.
I tried to read the full article but I think it's too recent to be on scihub. And like hell I'm paying for this.
