Dr. Robert Friedland, eminent neurologist and professor at the University of Louisville, Kentucky, recently published a compelling book titled 99 Lessons in Critical Thinking. In a wide-ranging conversation, Dr. Friedland delves into the deeper layers of medical practice, exploring what it means to truly listen, observe, and think critically in clinical settings. This is a timely and essential dialogue for medical professionals, especially doctors navigating an increasingly complex healthcare environment.
Deep Listening: The Foundation of Clinical Wisdom
Dr. Friedland begins by emphasizing that clinical attention goes beyond merely listening. It’s about truly hearing what the patient is saying, without the distraction of planning your next question or forming a response while they speak. True communication begins with acknowledging the patient’s words and reflecting them back: “So you’re saying you want to continue smoking because…” This reflection allows patients to feel heard and correct any misinterpretations.
He warns against assumptions based on social status, ethnicity, or appearance. In an era where electronic health records dominate attention, clinicians must fight to remain patient-centered. A high heel on an elderly patient, for example, might seem irrelevant, but it could explain a balance issue. Such details only emerge through attentiveness.
Dr. Friedland urges young doctors to observe from the moment they meet the patient. Their gait, dress, and even handshake can reveal crucial insights. Drawing on Arthur Conan Doyle’s Sherlock Holmes, he reminds us that patient clues begin in the waiting room.
Contextual Thinking: Seeing the Whole Patient
Understanding the patient’s situation in the context of their life is vital. A patient who appears non-compliant may simply be struggling with grief, financial constraints, or access to transportation. A missed appointment or an unfilled prescription may not stem from negligence but from barriers that only emerge if the physician asks.
Critical thinking means holding back from jumping to conclusions. Dr. Friedland recalls patients who showed up hours late not because they were careless but because public transport schedules made earlier arrivals impossible.
The Limits of Intuition and the Value of Rational Judgment
While experience and intuition play powerful roles in medicine, they can also mislead. Relying solely on past impressions without verifying assumptions can lead to incorrect diagnoses. He shares the example of an Alzheimer’s expert whose confident judgments were never confirmed through autopsy, rendering them speculative at best.
Dr. Friedland encourages balancing intuition with rational inquiry. Meditation, he suggests, helps cultivate awareness of one’s own thought processes and prevents being led astray by unchecked assumptions.
Aggressive Curiosity: The Drive to Learn
One of the most powerful takeaways is the idea that medical learning requires fierce curiosity. Dr. Friedland urges residents to follow up with patients they admitted, even after the case has been handed off. True learning happens when one seeks closure and understanding from the outcome, whether good or bad.
He compares education to lighting a fire, not filling a vessel. Doctors must actively pursue knowledge, not wait for it to arrive through formal channels.
Battling Time Constraints and Digital Distractions
Time is scarce and responsibilities many, especially for younger clinicians. Yet Dr. Friedland emphasizes the importance of prioritizing sleep, meaningful learning, and thoughtful interactions. He recounts asking questions of senior doctors—even at the risk of being rebuffed—as a vital learning tactic. Most experienced professionals are happy to share insights if asked.
Reforming Medical Education
Institutions, he believes, should stop teaching to the test and emphasize case-based evaluations. Real learning emerges from patient interactions and reflecting on historical medical judgments—good and bad. History is filled with errors made by brilliant minds, and understanding those errors cultivates humility and deeper comprehension.
Compassion Beyond Cure: Being Present When Nothing Can Be Done
Dr. Friedland offers candid insights into how emotional detachment often masks avoidance. Physicians frequently retreat from patients with grim prognoses out of helplessness or discomfort. But he asserts that presence, not solutions, is what matters. A hand on a shoulder or simply sitting in silence can offer more than words ever could.
He discourages the tendency to intellectualize illness, particularly among neurologists who focus heavily on clinical phenomenology. Instead, he advocates for conscious emotional engagement and acknowledging the weight of suffering, even when it cannot be alleviated.
The heart of Dr. Friedland’s message is simple yet profound: being present, staying curious, and listening deeply are not just soft skills. They are critical competencies that define excellence in medical care. And these are the habits that can and must be taught, practiced, and embodied across a lifetime in medicine.
Humanity Before Diagnosis
Dr. Friedland recalls a poignant moment early in his career at Mount Sinai. A professor, upon witnessing a patient crying after receiving a brain tumor diagnosis, attributed her tears to emotional incontinence caused by frontal lobe dysfunction. In truth, she was crying because she had just been told she had a brain tumor. The professor’s inability to see her emotional response as human, rather than clinical, reveals a deeper disconnect, one that Dr. Friedland argues must be addressed by all clinicians.
The Power of Words
Language matters. In clinical practice, the phrases we use shape not just communication, but also thought. Dr. Friedland critiques the common phrase “rule out,” noting that it implies a false sense of certainty. A clear chest X-ray does not definitively rule out pneumonia, just as an MRI cannot rule out Alzheimer’s disease. Even biopsies can be wrong. False confidence in language can close off further inquiry.
He highlights how euphemisms often distort reality, referring to a sunken ship as “not floating properly” or an exploded rocket as having undergone “an unanticipated disassembly.” In medicine, such verbal distortions can mislead and obscure clinical judgment. Precision in language is not just a matter of clarity, but of ethical responsibility.
Dr. Friedland also emphasizes the arbitrary divide between neurology and psychiatry. Both deal with the brain, and a neurologist should not defer all mental health concerns to psychiatrists without first exploring what they themselves can contribute.
Resisting the Data Deluge
In an era dominated by electronic medical records (EMRs), Dr. Friedland warns of a growing detachment from the patient. Notes become recycled, bloated with irrelevant or outdated information. Clinicians may face a screen, not the patient. He urges doctors to resist this drift and to position themselves physically and emotionally to engage directly with the person in front of them.
He points out that EMRs are often designed for billing and defensive documentation, not for patient care. In such an environment, the clinician’s vigilance and awareness become even more crucial.
Awareness in a Busy Clinic
Busy clinics and high patient volumes can lull clinicians into autopilot. Dr. Friedland shares strategies for remaining engaged. He personalizes every patient’s case, knowing not just their profession, but their context. For example, it’s not enough to know someone is in the Navy. Are they a nuclear engineer or a chef on a ship? That detail matters.
He stresses the importance of remaining alert to rare but dangerous diagnoses. A pediatrician may see a hundred children with mild symptoms before one presents with meningitis. Staying attuned despite the routine is essential.
Encouraging Critical Inquiry
One of the biggest barriers to critical thinking, according to Dr. Friedland, is discouraging questions. Many students learn early that asking “why” can be unwelcome. But critical thinking demands persistent curiosity. He tells the story of a teacher who insisted that alpha-synuclein deposits were the cause of Parkinson’s disease. But what causes those deposits? True inquiry continues beyond textbook answers.
Asking Why: A Clinical Imperative
Dr. Friedland describes a case of an elderly man who breaks his hip after a fall. Fixing the fracture is only part of the care. Why did he fall? Was it hypertension, poor balance, missed medication, or a playful dog? If the underlying cause is not addressed, the problem will recur. Surgeons may focus on repair, but comprehensive care demands deeper questioning.
Building a Culture of Collaborative Thinking
In multidisciplinary care, silos often persist. Doctors, nurses, and paramedics may work alongside each other but not together. Dr. Friedland urges openness to every member of the team. At his clinic in Cleveland, a patient’s second visit always included a group meeting with a nurse, doctor, and social worker. Sometimes, the patient needed the social worker more than the physician. A culture of shared inquiry and respect makes this possible.
Dr. Friedland’s message remains consistent: language shapes thought, curiosity drives clarity, and compassion anchors care. As technology advances and systems grow more complex, the clinician’s task is to stay grounded in human connection, precise in language, and relentless in asking, “Why?”
Seeing Through Different Eyes
Dr. Friedland begins with a simple but profound lesson: read the nursing notes. He explains how nurses often document critical behavioral and environmental observations that junior doctors overlook. Integrating these perspectives creates a more complete understanding of the patient.
Working within a multidisciplinary rehabilitation team, physical therapists, psychologists, speech therapists, neuromodulators, and holistic physicians, Dr. Friedland emphasizes the value of shared case conferences. Each discipline brings a different lens to the same patient, and when those perspectives converge in discussion, deeper insights emerge. This, he explains, is how critical thinking is cultivated through collaborative conversation.
Algorithms vs. Awareness
One of the core challenges Dr. Friedland identifies is the rise of algorithmic thinking. While clinical pathways and decision trees offer guidance, they risk eliminating thought. Following checklists without asking “why” can make medical practice mechanical. He warns that diagnostic tests, even highly sophisticated ones for conditions like Alzheimer’s, may accurately reflect brain changes but not necessarily the experience of the person.
In this, he distinguishes between treating the data and treating the human being. And he urges a shift in language, from “patient” to “person.” Patients are already in care. What about those in the community, undiagnosed, yet vulnerable? Preventive care, he argues, matters just as much, but is often undervalued because it isn’t reimbursed.
AI in the Clinic: Friend or Foe?
Asked whether artificial intelligence will sharpen or weaken critical thinking, Dr. Friedland is cautious. AI could help, he says, but it might also displace thinking altogether. He envisions a future where a computer in the exam room listens to the conversation, watches the patient’s movements, and makes suggestions, such as flagging a tremor or a pattern that resembles rabies. Such tools could support doctors, especially in avoiding low-quality care, but must never replace human judgment.
Thinking Like a Scientist Without a Lab
For those without access to large research labs, Dr. Friedland highlights the value of case studies and discarded clinical material. From tonsils to knee joints, biological material deemed uninteresting by pathologists could hold answers to important scientific questions. He cites the famous discovery in the 1970s by William Langston, who found young patients with sudden-onset Parkinsonism caused by a toxin. That pivotal finding began as a simple observation in an emergency room.
Even today, Dr. Friedland insists, meaningful research can begin with the humble case report. The history of science, he reminds us, is filled with accidental discoveries made by people who were simply paying attention.
Research Begins with a Question
Dr. Friedland recommends Introduction to the Study of Experimental Medicine by Claude Bernard as an essential read for young scientists. And for students and early-career doctors, he offers practical advice: volunteer in a lab. Opportunities often emerge from the initiative to ask, to show up, and to be curious.
Teaching What Can’t Be Googled
Reflecting on his decades of teaching neurology, Dr. Friedland explains the motivation behind writing 99 Lessons in Critical Thinking. With limited time to teach each group of students, he chose not to focus on memorizing cranial nerves, which can be found in any textbook, but instead on judgment, language, and reasoning.
He wanted to give students something deeper: the tools to think, question, and interpret rather than just recall. He wrote the book to ensure that what can’t be easily taught in a lecture—critical discernment, reflection, and mental flexibility, could still be passed on.
While the original title was 99 Lessons in Critical Thinking for Young Doctors, the publisher shortened it. Yet, as this conversation demonstrates, the lessons resonate just as deeply with seasoned clinicians, researchers, and thinkers.
As Dr. Friedland concludes, critical thinking in medicine isn’t about flashy results or rigid protocols. It’s about staying curious, staying human, and always asking, “What don’t I know yet?”
