Answer:
Overmier and Seligman have described the phenomenon of learned <u>helplessness</u> as the tendency to feel powerless in the face of events that we can't control.
In 1967, Overmier and Seligman conducted a research, which showed that dogs, once found in an uncontrollable situation such as unavoidable electric shocks, were incapable of escaping a different situation, although there was a possible escape in that situation. The phenomenon of learned helplessness is also commonly experienced by humans who, after repeatedly going through a stressful situation, believe they do not have control over the events. They fail to take any action, even if there is a possible solution.

This is not sufficient enought to deternmine wether someone is lying or not, is guilty or not.
