Wikipedia - Learned Helplessness ExperimentSummary
In the learned helplessness experiment an animal is repeatedly hurt by an adverse stimulus which it cannot escape.
Eventually the animal will stop trying to avoid the pain and behave as if it is utterly helpless to change the situation.
Finally, when opportunities to escape are presented, this learned helplessness prevents any action. The only coping mechanism the animal uses is to be stoical and put up with the discomfort, not expending energy getting worked up about the adverse stimulus.
I fear I've grown comfortable in my dysfunction.
