Article Extract

The diagnostic process is often said to exemplify the interplay between the art and science of medicine. Clinicians are required in their everyday work to use their expertise and skill to accurately execute the diagnostic process. When patients present with a problem, clinicians often respond intuitively, sometimes even without conscious effort. But sometimes this intuitive, ‘fast thinking’ can lead them astray.1
