Law values and protects individual autonomy as one of its core principles. In some circumstances, it even guards an individual's rights against majoritarian preferences. Law's focus is more often procedural than substantive. Law's roots are in democracy, and a balance of powers and adversarial methods of truth determination. All incline the legal profession to be skeptical of expert claims to know Truth.
Medicine is more results oriented and places greater trust in professional expertise than does law.
Whereas medicine is skeptical of premature claims to truth, it is inclined toward answers provided by experts. Doctors strive more for their ideas of beneficial outcomes for patients and tend to be less concerned about patients' autonomy. Indeed, some would say that doctors are acculturated to value their own autonomy more than that of their patients. Another crucial distinction in professional values is the law's strong commitments to open processes and disclosure. Law invites debate on most issues, using uncertainty and difference of opinion to stimulate discussion.
