No, enforced humiliation may 'work' in achieving its objectives, but so did Guantanamo Bay....
What is so wrong with being in your comfort zone, anyway? Why does it always have to be ripped away? Why do we only think that people can be of use to us if they aren't comfortable and secure in their surroundings?
Nobody would dream of asking a wheelchair-using employee to get up out of it for 10 minutes, so that everybody can 'laugh' and 'bond' over their discomfort, pain and humiliation when they fall flat on the floor feeling extreme vulnerability and loss of dignity - albeit gaslit to pretend that they find it hilarious too.
Therefore, why would you ask somebody with - not necessarily a disability as such - but with ASD, a very introverted personality type, a recently-bereaved person, somebody going through a miscarriage, somebody who is unable to afford to feed their kids - any number of needs, disabilities, conditions or challenging circumstances - to pretend that their life is all rainbows and lollipops, and actually believe that you've helped them? How is that any more helpful than telling somebody with clinical depression to 'cheer up, love' or 'snap out of it', as though it's that simple and they've never thought of that before?
Others will strongly disagree, but I actually think that enforced jollity (or, more accurately, enforced pretend jollity) can stray into controlling and abusive territory.
