Howarth has written an overview of the role of psychologists in the United Kingdom who might be involved in the information technology field. At the end of the chapter, he highlights the contributions psychologists can make in systems design and development. A strong point in the chapter is a good summary of the virtues of well-designed technology. Probably the weakest feature is the effect of poor proofreading.
In one section, the author refers to a government-supported research program but offers no bibliographic references for further information. Later, in commenting upon expert systems, he suggests that they are intended to replace expertise. The predominant view in the field is that such systems will be useful as an adjunct to the decision-making process, but will never be given the power Howarth suggests. However, the author is aware of the inherent problems in knowledge engineering and of size limitations for expert systems.
