Evidence-based medicine treats the "average patient" — but that patient doesn't exist.

Knowing a patient's history, family, stress, and habits predicts outcomes more powerfully than any checklist.

The therapeutic alliance is more important than the medication itself in determining treatment success.

15-minute appointments force algorithmic care, leaving patients unseen, unheard, and frustrated.

Imagine two people walk into their psychiatrist’s office on the same day. Both are struggling with low mood, poor sleep, and fatigue. Both leave with the same prescription, the same dose, and the same follow-up appointment scheduled in six weeks. One gets better. The other doesn't. Why?

This story is repeated millions of times each year, and raises the question: Should doctors treat diseases, or should they treat people?

Evidence Based Medicine

For most of the 20th century, medicine operated on a simple premise: find the best treatment for a given condition, test it on large populations, and apply that knowledge universally. This approach —called evidence-based medicine (EBM)— was formalized in the 1990s, largely by Canadian physician David Sackett.

Sackett described the goal of EBM is to replace hunches and habits with data and clinical trials. Clinical guidelines were developed involving protocols that tell doctors which drug to prescribe first, what dose to use, when to escalate treatment, and when to refer a patient to a specialist. Today, these guidelines are often incorporated into electronic health records, where they guide physicians toward the statistically optimal choice for the average patient.

But there’s a problem with this model: the average patient doesn’t exist. The studies that generate these guidelines often underrepresent women, older adults, children, people of color, and anyone with more than one diagnosis. The "average" is a statistical construct. And when you apply a treatment designed for a construct to a human being, the treatment doesn’t always work.

Treating the Person in the Room

There’s another tradition in medicine. This tradition is older than algorithms, older than clinical trials, and it doesn’t begin with a diagnosis but rather with a question: Who is this person?

This approach starts with the assumption that effective care involves knowing your patient. Sounds revolutionary, but it’s not. It requires a clinician to invest time in getting to know their patient — not just their symptoms, but their history. Their work. Their family. Their fears. Their habits. Their preferences about medication. Their history with past treatments, and what "getting better" means to them personally.

This is not pseudoscience. It’s clinical science. A patient's occupation, family situation, sleep environment, financial stress, and social support system are important details. They’re some of the most powerful predictors of health outcomes available to any physician. A doctor who knows that her patient is a firefighter working 24-hour shifts, or his patient is a single father of three with no time to fill prescriptions, or her patient grew up in a household where mental illness was treated as a moral failing — that doctor has access to information no algorithm or checklist will identify.

The Science of Knowing Your Patient

The therapeutic alliance, which is the quality of the relationship between a clinician and their patient, is one of the most powerful predictors of treatment outcome in psychiatry and psychology. A 2017 meta-analysis examined over 1,000 patients and found that a positive physician-patient relationship was associated with better outcomes even in medication-based treatment — not just psychotherapy. The strength of the relationship mattered as much as the drug itself.

Similarly, a 2006 psychotherapy trial found the quality of the therapeutic alliance predicted outcomes across every treatment condition, whether patients were receiving psychotherapy, medication, or placebo. A clinician who takes time to understand their patient isn’t just being kind. They’re being effective.

A 2024 meta-analysis found that the emotional bond between a patient and their clinician, a bond which comes from feeling known and understood, is among the most important determinants of what happens in treatment. Patients who feel heard and seen get better more often than patients who feel they have been reduced to a diagnosis or a number.

The Art of Pattern Recognition

There is something else the algorithms cannot replicate: the trained eye of a seasoned clinician.

When an experienced clinician meets a new patient, they’re drawing on years of encounters, thousands of patients, hundreds of variations, and countless combinations of details. This is called pattern recognition, and research shows it’s a powerful tool that is employed by experienced, successful practitioners.

A 2023 review reported that expert clinicians rely on fast, intuitive pattern recognition that allows them to identify subtle diagnostic signals in ways that are not revealed in protocols or checklists.

Pattern recognition in psychiatry is complex. An experienced clinician might notice a patient's animated speech and pacing that doesn’t match the dark circles under their eyes. Or they recognize that the man sitting across from them has the affect of someone who is depressed, despite his statement that he’s happy. Or they recognize a pattern they've observed before when a man focuses on his marital problems, rather than his problem with alcohol.

What Gets Lost When the Appointment Lasts Fifteen Minutes

The modern healthcare system is not designed to support the kind of medicine described above. The average primary care appointment in the United States lasts about fifteen minutes. In psychiatry, "medication management" visits can be as short as ten minutes. There is barely enough time to update a medication list, let alone ask how their job is going.

This is not a failure of individual practitioners. Most clinicians went into healthcare because they wanted to know their patients as human beings and help them. The shortening of appointment times is a structural problem — one that pushes clinicians to use algorithmic medicine.

The result is that patients often feel unseen and unheard. They answer the questions on the intake form, receive a diagnosis that fits those answers, and walk out with a treatment plan that may not work, not because the treatments are bad, but because the doctor didn’t know enough about them to develop an effective, individualized treatment plan.

The solution to our current healthcare crisis is deceptively simple. It involves training clinicians who listen carefully, ask questions that go beyond the symptom checklist, and treat their patients as unique human beings rather than diagnoses or CPT-codes.
