It has been observed in a number of relationships that management of 'ego' is a very difficult issue. Often people stick to their stand, sometimes unreasonably, even when they know that they themselves are in wrong or at fault, This often happens in boss-subordinate, social, familial and other inter-personal relations.
In India, several deaths are reported in road rage cases, where in case of even very minor accidents, out of ego the situations have reached to severe attacks on the weaker side and even killing the other side. And, the killer repents the loss of emotional intelligence in that moment while in jail, the whole life.
How can the malaise of excessive ego be controlled or minimized? Are there any research on this issue?
