We experience uncertainty with regard to the stranger's attitudes, feelings and beliefs. We are also uncertain of how to explain the stranger's behavior. Motivation to reduce this uncertainty is more acute when we expect to have further interactions with the stranger, or when they are a potential source of benefit. We may reduce our uncertainty and increase the accuracy of our predictions by gaining more information about the stranger. There are three basic strategies for gathering such information. One may passively observe the stranger. One may actively seek out information from other friends of the stranger or from books. Finally,one may seek information directly from the stranger by interacting with them and asking questions. Also, offering information about one's self often prompts reciprocal offerings of information from another. The increased uncertainty in interactions with strangers is accompanied by higher levels of anxiety, as we anticipate a wider array of possible negative outcomes. We may worry about damage to our self-esteem from feeling confused and out of control. We may fear the possibility of being incompetent, or being exploited. We may worry about being perceived negatively by the stranger. And we may worry that interacting with a stranger will bring disapproval from members of our own group.
