It’s mistaken (and somewhat sad!) to take a cynical attitude like that given the implications of the research. The most exciting part of these type of studies is the ability to take depressive people and ‘kick’ them out of the cognitive ruts they are in. Those cognitive ruts are often world-views, thought structures and learned behaviours from childhood or their parents which constantly reinforce that the sufferer is…
Wait, so the idea is to see other people for "who they are"... but they won't do the same. It sure can "restore faith in humanity" and yourself, but what happens when you get hit with a dose of reality? That everyone struggles... individually. And most people don't actually care about you. Back to depression it is?
Well... yeah. I mean, imagine you had super critical parents who picked on your every mistake as a child. Now you suffer from social anxiety and feel intense shame and fear in public because you think everyone is constantly criticizing you and talking about you.
Being able to relax and be yourself knowing that most people won’t care either way is a huge step forward.
