Donald A. Norman Quote

Hindsight is always superior to foresight. When the accident investigation committee reviews the event that contributed to the problem, they know what actually happened, so it is easy for them to pick out which information was relevant, which was not. This is retrospective decision making. But when the incident was taking place, the people were probably overwhelmed with far too much irrelevant information and probably not a lot of relevant information. How were they to know which to attend to and which to ignore? Most of the time, experienced operators get things right. The one time they fail, the retrospective analysis is apt to condemn them for missing the obvious. Well, during the event, nothing may be obvious. I return to this topic later in the chapter.

About Donald A. Norman

Donald Arthur Norman (born December 25, 1935) is an American researcher, professor, and author. Norman is the director of The Design Lab at University of California, San Diego. He is best known for his books on design, especially The Design of Everyday Things. He is widely regarded for his expertise in the fields of design, usability engineering, and cognitive science, and has shaped the development of the field of cognitive systems engineering. He is a co-founder of the Nielsen Norman Group, along with Jakob Nielsen. He is also an IDEO fellow and a member of the Board of Trustees of IIT Institute of Design in Chicago. He also holds the title of Professor Emeritus of Cognitive Science at the University of California, San Diego. Norman is an active Distinguished Visiting Professor at the Korea Advanced Institute of Science and Technology (KAIST), where he spends two months a year teaching.
Much of Norman's work involves the advocacy of user-centered design. His books all have the underlying purpose of furthering the field of design, from doors to computers. Norman has taken a controversial stance in saying that the design research community has had little impact in the innovation of products, and that while academics can help in refining existing products, it is technologists that accomplish the breakthroughs. To this end, Norman named his website with the initialism JND (just-noticeable difference) to signify his endeavors to make a difference.
