I think more convenient and user friendly is a bit of a stretch.
My wife gets confused by the remote and different profiles. My parents needed me to explain how to use Netflix more than once. Saying going to your PC and finding a torrent is convenient and user friendly isn't true. But the point that having to search where to stream a particular movie or show isn't user friendly is also true.
You can read it that way, or that they report higher pain intensity, or that they have been refused medication in the past so are likely to exaggerate in order to get what they need.
The problem is we don't have an objective way to measure pain. We can control the stimulus, but is it possible that one person experiences pain differently from others. By aggregating data you can find trends among populations. Hiding this information doesn't serve anyone.
Knowing what groups tend to over/state pain is useful. The format they show it in is offensive, some straight up graphs and numbers showing what the trends are would be better.
