The expectancy disconfirmation model (EDM) posits that disconfirmation (the difference between expectations and perceived performance) affects citizen satisfaction. Van Ryzin experimentally manipulated expectations and performance and found a direct effect of performance, but no disconfirmation. We performed: an exact replication; a conceptual replication with extreme manipulations; a conceptual replication that reversed the order of a performance and expectations manipulation. Study 1 and 2 reproduced original findings. In contrast, study 3 indicates that expectation cues are retrospectively used to anchor prior experiences of performance. As the rational assumptions underlying the EDM are increasingly challenged, we need a better understanding of how cognitive biases shape citizen satisfaction.
