Projection Bias


Projection bias is exemplified by the “shopping while hungry” phenomenon, in which people overbuy at the supermarket when they’re hungry, incorrectly anticipating the kinds and amount of food they’ll want later, when not very hungry. We know people incompletely anticipate future motivational states, like hunger in the previous example, but don’t know much about why they do this. This project seeks to identify the mechanisms at work that lead to this strange behavior.
