How are perceptions created?

"People accept the reality with which they are presented". People's various experiences formulate their values, morals, ethics, etc. which all in turn influence their decisions and perceptions. Thus each individual will have their own unique perception regarding an issue, due to the unique way they have been brought up. The different stereotypes and opinions you choose to acknowledge, along with the one's you yourself have formulated - whether it be from various experiences, etc., will all influence your perceptions regarding people, stances on issues, or even perceptions about life itself.
