In 1966, psychiatrist Charles Hofling posed a simple but frightening question: How far is a person willing to go in carrying out an order from an authority figure, even if that order is contrary to common sense, rules, and ethics? He suggested that in a hierarchical system such as a hospital, the doctor's instruction would be carried out almost automatically by the nurse. The results of his experiment were far more disturbing than he could have imagined, and to this day serve as a stark reminder of the hidden mechanisms of our psyche.
The script developed by Hofling was thought out to the smallest detail. A man, introducing himself as Dr. Smith (not his real name), called a U.S. hospital and asked a nurse to give an urgent injection to a patient. It was about the drug "Astroten". The doctor insisted on administering 20 mg, promising to sign the necessary documents later, as soon as he got to the hospital.
In fact, Astroten did not exist. In the first aid kit there was a dummy bottle, the label of which clearly stated: "Astroten. The maximum daily dose is 10 mg." Thus, the nurses were asked not only to comply with the oral order, but also to consciously exceed the specified norm by two times.
Each nurse who agreed to this manipulation was faced with the need to violate at least four fundamental rules:
Before the start of the main stage, Hofling conducted a survey in a control group of 12 nurses and 21 medical students. He described the scenario to them and asked them what they thought their colleagues would do. The vast majority — 10 nurses and all 21 students — confidently stated that the nurses would refuse to comply with such an order.
The reality turned out to be crushing. The main experiment involved 22 nurses. The researchers, who were expecting a refusal, stopped each nurse who agreed right at the door of the room before she could administer the injection.
They were stopped twenty-one times. Twenty-one nurses out of twenty-two were willing to inject the patient with a potentially lethal dose of an unknown drug, violating all imaginable rules and instructions. Only one of them refused. Moreover, a follow-up survey found that 10 of the 22 nurses admitted to having previously followed similar verbal instructions.
The results of Hofling's experiment are not an indictment of nurses, but a demonstration of the power of the situation and the cognitive distortions to which we are all subject. Several factors play a key role here.
The phrase "I'll sign the documents later" effectively relieved the contractor of psychological responsibility. The nurse did not see herself as a decision-maker, but as a tool in the hands of the doctor. The entire burden of possible consequences was mentally shifted to an authoritative figure.
In the medical hierarchy, the doctor has historically had indisputable authority. Doubting his competence or instructions was considered a violation of subordination. Nurses were trained to trust doctors, and this pattern of behavior worked automatically, suppressing critical thinking.
Hofling's experiment is often compared to the famous study by Stanley Milgram (1963), where subjects were willing to inflict pain on another person ("electric shocks") at the scientist's orders. Both studies show that it is not personal moral qualities, but the pressures of the situation and authority that often determine our actions.
Hofling's experiment proves that authority is no substitute for critical thinking. The most important question to ask in response to any instruction is not "Who said that?" but "Why is this right and safe?" Trust should be conscious, not blind.
Hofling's study and other similar works have led to major changes in medical protocols around the world. Strict rules for the verification of verbal and telephone appointments, double verification and electronic document management systems were introduced, minimizing the human factor.
However, the lessons of this experiment go far beyond the hospital walls. They are relevant wherever there is a hierarchy: in business, where an employee can receive a dubious order from the boss; in finance, where the investor blindly trusts the "guru"; in the media space, where we take the opinion of experts on faith without checking the facts. The tendency to delegate responsibility and turn off critical thinking in the presence of authority is not a flaw of individuals, but a universal vulnerability of the human psyche.
The Dr. Smith experiment is a timeless reminder that real responsibility is always personal. The ability to stop in time, ask a question and question authority when his instructions contradict logic and security is not an act of disobedience, but the highest manifestation of professionalism and humanity.
