Yep, and in fact it was project MKUltra that came up with the concept of "learned helplessness" (another name for induced depression) as a result of the torture experiments on people like the Unabomber. The funny thing is that civilian psychiatrists continue to insist that depression can only develop in genetically susceptible individuals and cannot be due to environmental stimuli only. Yet, the military/intelligence bases a lot of its "enhanced" psyops/interrogation techniques on the idea that stress/torture is perfectly sufficient to induce depression (even suicide) in ANY individual.

Interestingly enough, when I tried to bring up the issue of "learned helplessness" as a very common state of mental health these days, I got heavily downvoted in another thread (though lately the posts seem to have recovered a bit).

To insist that learned helplessness is limited to non-human animals amounts to denial of evolution.
