Medical mistakes often are responsible for patient injury and sufferin
g, but not all such mistakes are negligent. In the United States, inju
red patients have recourse to legal action under the common law. The m
edical malpractice tort trial system is intended to provide compensati
on for patients who have been negligently injured and to deter future
negligent acts by physicians. The deterrent function of torts largely
rests on practitioners' capacity and willingness to internalize, or 'p
rocess', the lessons of tort trials. However, physicians' willingness
or ability to process the tort deterrent signal, while widely assumed
in much contemporary legal writing on medical malpractice, has never b
een empirically verified. This study is a qualitative assessment of ho
w practicing physicians process the tort deterrent signal. We intervie
wed a random sample of 47 internists, surgeons, and obstetrician/gynec
ologists from New York State as part of the Harvard Medical Practice S
tudy. The interviews reveal three notable findings: physicians in our
sample largely define medical negligence by reference to moral qualiti
es of the practitioner; they claim that lawyers and the legal process
of tort trials lack the moral authority to guide medical practice; and
finally, while they consequently reject the lessons of lawyer-dominat
ed, confrontational tort trials, they indicate that they would respond
more favorably to hospital-based, physician-led, educational quality-
control measures. Based on these findings, we identify several potenti
al impediments to the receipt and processing of the tort deterrent sig
nal by individual physicians and we suggest that the interview results
support the notion of institutional liability for medical malpractice
