New research shows customers underestimate how much service times can vary
A study from the University of Florida Warrington College of Business finds that people often overestimate how predictable wait times are.

Study findings on customer bias
The research published in Manufacturing & Service Operations Management indicates that customers frequently underestimate the variation in service durations. This behavioral bias, known as overprecision, influences whether individuals choose to join a line or pay for a specific service. Na Zhang, an assistant professor at Wichita State University, explained that this common cognitive bias shapes both individual decisions and entire service systems.
Impact on business pricing models
Businesses can use this misconception to charge higher prices when customers cannot see the length of a queue. In settings where wait times are unobservable, the optimal price is higher than traditional models suggest. The gap between revenue-maximizing strategies and customer expectations creates new opportunities for companies to adjust their pricing.
