Expert systems have no "common sense". They have no understanding of what how their recommendations fit into a larger context. If MYCIN (a commonly-used expert system) were told that a patient who has actually received a gunshot wound is ‘bleeding to death’, the program would attempt to diagnose a bacterial cause for the patient's symptoms.
Expert systems can make (or miss) absurd errors, such as prescribing an obviously incorrect dosage of a drug for a patient whose weight and age are accidentally swapped by the clerk.
