Should doctors ever be professionally required to change their attitudes?

The General Medical Council instructs doctors not to allow their personal beliefs to interfere with their practice. But if attitudes can threaten to impact negatively on a doctor's practice then the question arises: should doctors ever be professionally required to change their attitudes? In this paper I suggest that doctors should be required to amend their attitudes if two conditions are met, namely: (1) the doctor has an attitude that if neglected by the doctor will (or is very likely to) compromise his or her fitness to practise; and (2) the only way in which the doctor can prevent that attitude from compromising his or her fitness to practise is by changing the attitude. I also answer three objections that might be raised against the position that I advance.
