This document discusses context effects in decision making and how preferences are often constructed based on the available choice set rather than revealed. It focuses on the attraction effect, background alternatives, and phantom alternatives. The study aims to analyze interactions between these different context effects and how past experience may conflict with current choice sets. Four experiments were conducted manipulating placement and types of decoys to test for context effects. Results showed decoys were able to shift preferences when providing information conflicting with background experience. People were more likely to base choices on contingent information rather than past experience when in conflict.
