According to UCLA Anderson Associate Professor Bruce Carlin, the notion of "search fatigue" is ... well let's quote him from a recent paper he co-authored with his Anderson colleague Assistant Professor Florian Ederer.
Quoting from their working paper called (simply enough) "Search Fatigue," they write "The fact that search is tiring (and can aﬀect future behavior) has been overlooked. Fatigue from searching in one period may aﬀect the costs and incentives to become informed in future periods."
In the above video, Carlin notes that "the more you search, the more worn out you get, the more likely the next time you're going to make a decision you may not search as hard." This, of course, has implications for the decisions consumers make.
Check out the above video as Professor Carlin provides the details.
