Thanks for asking for real data about this. I was only giving my very humble opinion about what could happen, I would like to know some links to literature and actual experiments with basic income. I think that laziness is learned and you need to be kicked strongly to move in a doers direction. In a weak economy with no expectations for people to progress laziness and hopeless bloom, if basic income is a step in the right direction it should be along with a way to foster better expectations. Your are not in an asylum for live.

Here are two articles that gave me insight: http://mondediplo.com/2013/05/04income and https://en.wikipedia.org/wiki/MINCOME

Basically, people who were working out of desperation worked less, otherwise people used the money to ensure food safety, invest in businesses or improving their lives.

I really don't think "lazy" is a valuable label. It tends to be applied when there are underlying causes for the supposed "laziness". When those causes are repaired the laziness tends to go away. For example: illness, precarity, hopelessness (as you mentioned), a lack of opportunities. I'd suggest doing away with the overly simplistic "lazy" and using more accurate words which express the underlying causes.
