Donald A. Norman Quote
Once people find an explanation for an apparent anomaly, they tend to believe they can now discount it. But explanations are based on analogy with past experiences, experiences that may not apply to the current situation. In the driving story, the prevalence of billboards for Las Vegas was a signal we should have heeded, but it seemed easily explained. Our experience is typical: some major industrial incidents have resulted from false explanations of anomalous events. But do note: usually these apparent anomalies should be ignored. Most of the time, the explanation for their presence is correct. Distinguishing a true anomaly from an apparent one is difficult.
