Consumers Perceive That Whole-Number Average Ratings Reflect Less Variable Distributions
Consumers perceive less dispersion in the distributions of whole-number average ratings (e.g., 4) compared to those of non-whole-number average ratings (e.g., 4.10)—even when this is statistically unlikely. This effect is a product of the representativeness heuristic and drives consumer choice because consumers frequently prefer products with less variability.
