Abstract

Consumers often need to predict their liking of a product based on product fragments (e.g., choosing paint colors from tabs with different paint colors). We call this type of preference forecasting the mental extrapolation task. Drawing on research on affective forecasting and memory processes, we predicted that, compared to their actual product experience, 1) forecasted preferences based on fragments were more extreme; 2) predictions were excessively anchored by evaluations of the fragments per se; and 3) familiarity with the product fragments increased the magnitude of these forecasting errors. Two lab experiments using an Internet shirt-buying task found support for these predictions.
