Helplessness is a feeling experienced when we predict disappointment.
Helplessness is an emotion derived from appraising disappointment.
We feel helpless when we get low marks on a test despite our effort. However, we don't feel it because of the test's score, but from predicting that the next test will go poorly too so any efforts would be useless. If we clearly know the reason why we did poorly on the test we don't feel helpless. Helplessness is a sense that we cannot achieve what we hope.
An inferiority complex is formed when comparing abilities causes one to feel helplessness because we live in competitive society, same as a superiority complex. If a person's hope is to exceed someone else, but they can't, this is called an inferiority complex.
A person who feels helpless stops being proactive. They think that it is doomed to failure from the start, and then they stop trying to do things. When they have to do something they act too slowly, because they feel that they cannot succeed. They become indecisive.
Helplessness is disappointment sustained by memory and has little value in evolution. It only causes the stagnation of some activities, and a shift in your lifestyle through reflection.
Researchers found that when some mammals are captured by carnivorous animals, they are surprisingly quickly to stop resisting. If fellows of their heard appears they start to resist again, and sometimes can escape. This means that they often are eaten without any useless struggling, and not after exerting all of their energy and being taken down. Mammals may feel helplessness.
