Research indicates that most people tend to accept and agree with new people and information when they are similar to what we have recorded as being positive on mental 'tapes' from our previous experiences.   

People or information that do not 'fit' into our previous experiences tend to be viewed with some degree of apprehension or suspicion.   This behavior makes it most difficult for us to be truly "open-minded" when faced with new/different people or situations.   

Wellness psychology encourages us to learn new ways of learning emotional and behavioral views when approaching different people and situations.
