According to Newberg and Waldman, beliefs shape personal behaviors and spiritual ethics throughout life, governing nearly every aspect of life. They are our most important human commodity and help people flourish and survive. They can also be used to suppress others and justify immoral or sadistic acts. They can also connect one with transcendent dimensions of experience, and give inspiration and hope, essential tools for confronting moments of confusion and doubt. They help people build civilizations, make revolutions, create music and art, determine our relationship to the cosmos, makes us fall in love and drive us into hate. Once beliefs are established, their validity is rarely challenged even when the person is faced with contradictory evidence. The brain is instinctually prone to reject information that does not conform to one’s prior experience and knowledge. It has a propensity to reject any belief that is not in accord with one’s own view. The human brain can alter its system of beliefs far more rapidly than that of any other organism on the planet.
