Information Overload and the Nonrobustness of Linear Models: A Comment on Keller and StaelinCoauthor(s): John van Rossen.
does the Keller and Staelin investigation close the book on the information overload debate? In our view, refinement of the relationship between information quality and quantity is valuable, but a strong argument can be built that their data do not offer an unambiguous demonstration of information overload. Specifically, it is possible to show that a similar set of overload results could have been obtained within their methodology even if consumers had an unlimited ability to process information.
