According to a study from 1961, which group of doctors was found to often withhold information from patients?

The correct answer highlights a broader trend identified in the 1961 study regarding the behavior of doctors in relation to patient communication. The study demonstrated that a significant number of doctors, rather than just a specific subset, tended to withhold information from their patients. This practice could stem from various reasons, including the belief that withholding certain diagnoses or prognoses would protect patients from distress.

This answer underscores the general attitude of the medical community at that time, indicating that it was not an isolated occurrence limited to just a few individuals or specialties. By stating "most doctors," the answer encapsulates the findings of the study, reflecting a widespread pattern in patient-doctor interactions that raised ethical concerns about transparency and informed consent in medical practice.
