Background: It is sometimes difficult to make a diagnosis in podiatry and expert systems may help to improve the situation. Card Sorts Methodology may be a useful technique to explore attitudes towards the use of expert systems within a domain.

More recent work in knowlegde acquisition and in requirements acquisition has changed the situation by developing more powerful, formalized versions of card sorts.

Method: Two groups of seven participants composed of Podiatry lecturers and Nursing lecturers were asked to sort cards containing various diagnostic aids.
Results: Expert systems are viewed as very different in kind from the other diagnostic aids
