People like to make their own decisions in small matters, but making decisions on difficult, fundamental questions require facing up to psychological conflict, and most people hate psychological conflict. Hence they tend to lean on others in making difficult decisions. The majority of people are natural followers, not leaders, but they like to have direct personal access to their leaders and participate to some extent in making difficult decisions. At least to that degree they need autonomy. Failure to obtain goals leads to frustration and lowering of self-esteem.
Frustration leads to anger, anger to aggression, often in the form of spouse or child abuse.
It has been shown that long-continued frustration commonly leads to depression and that depression tends to cause guilt, sleep disorders, eating disorders and bad feelings about oneself. Boredom too tends to cause excessive pleasure-seeking since, lacking other goals, people often use pleasure as a goal. See accompanying diagram. The foregoing is a simplification. Reality is more complex, and of course deprivation with respect to the power process is not the ONLY cause of the symptoms described.
