Reality is created in the mind through perception and interpretation of external data. Perception involves selecting, sorting, and interpreting environmental stimuli using the five senses. It is influenced by psychological and physical conditions, language, experiences, expectations, and other factors. Sharing perceptions with others through empathic and deliberative listening allows for reality testing and reduction of distortions between individual realities. People generally desire to maintain stasis or absence of change in their realities for comfort.
