I must admit, I don't see how positive thinking could possibly help?

Assuming suicides are usually a result of violence (bullying by peers, pressure by parents and teachers...). Wouldn't it be better to show practical ways out of it? Saying "I'm so great and thankful" while bullies pounce on you might feel rather hollow quickly?

Don't get me wrong, this seems to be set up as an experiment, which seems like a good thing. Maybe they'll find it will actually help.

Your argument sounds like "something has to be done, because..." - but something is not always the right thing.
