Information Overload and the Nonrobustness of Linear Models: A Comment on Keller Staelin.

The article comments on the 1987 paper "Effects of Quality and Quantity on Decision Effectiveness," by professors Rick Staelin and Kevin Keller, which discussed whether it was possible to provide consumers with too much information when making choices. The article states that Keller and Staelin found that when information quality was held constant, increases in information had a strong negative effect on decision accuracy. The article's critique centers on Keller and Staelin's use of inferred choice errors when identifying consumer error in a given choice.
