As a self-discrepancy arises between who an individual currently is and who they aspire to become, feelings of tension arise. Reactions to this stress are based on various personal beliefs. Our feelings of our potential to reach our desired state can be affected by our orientation of locus of control, or where we believe control is derived from within our life. In the present research, we examine how a person's locus of control--whether they are internal by attributing outcomes to their own actions or external believers that fate and chance drive their life outcomes--affects their reaction to a self-discrepancy in a domain that is important to them, and how this affects valuation of the products used in that domain. We found that while internals and externals behave similarly under feelings of high competence (baseline condition) when a self-discrepancy is not evident, reactions differed under the opposing condition of feeling less competent during their goal pursuit. Externals did not significantly change their belief in the product regardless of the condition (high vs. low competence) while internals took the defeat heavily by significantly decreasing their belief that the goal-related product would help them achieve their goals and decreased their willingness to pay for it.
