The Ancients Were More Caustic
Taleb uses jokes by Martial, later anecdotes collected by Montaigne, and other historical accounts to discuss harm from treatment and biased attribution. The stories express longstanding suspicion of medical practitioners rather than measuring treatment outcomes.
THE IDEA
This problem of iatrogenics is not new—and doctors have been traditionally the butt of jokes.
Martial in his epigrams gives us an idea of the perceived expert problem in medicine in his time: “I thought that Diaulus was a doctor, not a caretaker—but for him it appears to be the same job” (Nuper erat medicus, nunc est uispillo Diaulus: quod uispillo facit, fecerat et medicus) or “I did not feel ill, Symmache; now I do (after your ministrations).” (Non habui febrem, Symmache, nunc habeo).
The Greek term pharmakon is ambiguous, as it can mean both “poison” and “cure” and has been used as a pun to warn against iatrogenics by the Arab doctor Ruhawi.
An attribution problem arises when the person imputes his positive results to his own skills and his failures to luck. Nicocles, as early as the fourth century B.C., asserts that doctors claimed responsibility for success and blamed failure on nature, or on some external cause. The very same idea was rediscovered by psychologists some twenty-four centuries later, and applied to stockbrokers, doctors, and managers of companies.
According to an ancient anecdote, the Emperor Hadrian continually exclaimed, as he was dying, that it was his doctors who had killed him.
Montaigne, mostly a synthesizer of classical writers, has his Essays replete with anecdotes: A Lacedaemonian was asked what had made him live so long; he answered, “Ignoring medicine.” Montaigne also detected the agency problem, or why the last thing a doctor needs is for you to be healthy: “No doctor derives pleasure from the health of his friends, wrote the ancient Greek satirist, no soldier from the peace of his city, etc.” (Nul médecin ne prent plaisir à la santé de ses amis mesmes, dit l’ancien Comique Grec, ny soldat à la paix de sa ville: ainsi du reste.)
When to use it
Before undergoing a medical treatment, consider the potential for iatrogenic harm and seek second opinions.
When evaluating the success of a business strategy, examine whether attribution biases are inflating perceived effectiveness.
In policy-making, assess the possibility that a new rule or program may create unintended negative side effects.
During personal development, question whether the advice or methods you follow are truly helpful or if they carry hidden costs.
FROM THEORY TO EVERYDAY LIFE
In practice
Martial's Epigrams
Roman poet Martial mocked doctors: one epigram describes Diaulus who was first a doctor then a grave-digger, implying the professions were equally fatal; another laments that a visit from Doctor Symmache turned a healthy person into a sick one.
Hadrian’s Complaint
According to the anecdote Taleb recounts, Hadrian blamed his doctors as he lay dying. The story illustrates suspicion of treatment; it does not establish what caused his death.
Lacedaemonian Longevity
A Spartan was asked why he lived so long and replied, 'Ignoring medicine,' a quip that expresses distrust of medicine rather than evidence about its effects.
A MOMENT TO REFLECT
Put it to work.
Think of a time when a well-intentioned intervention in your own life (medical, professional, or personal) ended up causing more harm than good. What factors contributed to that outcome?
How might the attribution problem—taking credit for success and blaming failure on external factors—affect decision-making in your field?
What are some modern examples of iatrogenics beyond medicine, such as in technology, policy, or business?
