In "Of Two Minds," anthropologist Tanya Luhrmann does something disarmingly simple and devastatingly effective: she studies American psychiatry the way an anthropologist would study any other culture—from the inside, with participant observation, deep listening, and an outsider's ability to notice what insiders take for granted. Over several years, she embedded herself in psychiatric residency programs, attending rounds, sitting in on supervisory sessions, observing how young doctors learned to think about mental illness and how the profession's internal divisions shaped the care patients actually received. The result is a portrait of a profession at war with itself, and a profound meditation on what gets lost when the mind is reduced to the brain.

The "two minds" of the title refer to the two dominant paradigms that have competed for psychiatry's soul: the psychodynamic tradition, which understands mental distress as arising from the complexity of human relationships, inner conflict, and life history; and the biomedical model, which treats it as fundamentally a brain disease requiring pharmaceutical correction. Luhrmann's fieldwork captured American psychiatry at a pivotal moment when the biomedical model was decisively winning this war, reshaping residency training, clinical practice, and the very way psychiatrists understood their patients and themselves. Her account of this transformation is neither nostalgic for psychoanalysis nor triumphalist about pharmacology. Instead, it reveals with anthropological precision how institutional forces, economic pressures, and cultural assumptions—not just scientific evidence—determined which framework prevailed. For IMHU's community, this book provides an essential lens for understanding why the psychiatric system works the way it does, and why so many people with spiritual and non-ordinary experiences find themselves pathologized rather than understood.

One of Luhrmann's most illuminating findings concerns how psychiatric training literally teaches residents what to perceive. In psychodynamically oriented programs, residents learned to listen to the story—to hear a patient's symptoms as expressions of underlying emotional conflicts, relational patterns, and life experiences. The patient was understood as a whole person whose distress made a kind of sense when you knew enough about their inner world. In biomedically oriented programs, residents learned to identify symptoms—to match observable behaviors and reported experiences against diagnostic criteria that pointed toward specific pharmaceutical interventions. The patient was understood primarily as a diagnostic entity whose brain chemistry needed correction.

These aren't just different theoretical orientations. They produce genuinely different perceptual experiences for the clinician. A psychodynamically trained resident sitting with a depressed patient might notice that the depression intensified after the death of the patient's mother and connects to childhood experiences of abandonment—seeing a meaningful narrative that suggests therapeutic exploration. A biomedically trained resident sitting with the same patient might notice the sleep disturbance, appetite changes, and psychomotor retardation—seeing a symptom cluster that suggests an SSRI prescription. Neither is seeing incorrectly, but each is seeing partially, and what gets left out of the clinical gaze doesn't disappear. It just goes unaddressed. Luhrmann's insight is that this selective perception isn't a conscious choice—it's a trained incapacity, built into clinicians through years of supervised practice that teaches them what counts as clinically relevant and what doesn't.

Luhrmann documents how the biomedical model's victory over psychodynamic psychiatry was driven as much by institutional and economic forces as by scientific evidence. Managed care transformed the economics of mental health treatment, making the fifteen-minute medication check far more financially viable than the fifty-minute therapy session. Insurance companies preferred discrete diagnoses with standardized treatments over the open-ended complexity of psychodynamic formulation. Pharmaceutical companies invested billions in promoting the understanding of mental illness as brain disease, funding research, medical education, and public awareness campaigns that embedded the chemical imbalance narrative in both professional and popular consciousness.

None of this means the biomedical model is simply wrong. Psychiatric medications help millions of people, and neuroscience has produced genuine insights into the biology of mental distress. But Luhrmann shows that the model's dominance reflects institutional power and economic incentive at least as much as scientific superiority. The evidence for the chemical imbalance theory of depression, for instance, was always far more equivocal than the public narrative suggested. The biomedical model prevailed not because it explained mental illness more completely than psychodynamic approaches, but because it fit more comfortably within the healthcare system's economic structures, the pharmaceutical industry's business model, and the broader cultural preference for quick, technological solutions to complex human problems. Understanding this history matters for anyone trying to change the system, because it reveals that the current paradigm's authority rests on foundations that are partly scientific and partly political.

Perhaps the most poignant thread in the book concerns what happens to the person—the actual human being in distress—when their suffering gets translated into diagnostic categories and treatment protocols. Luhrmann observed that as residents progressed through biomedically oriented training, many underwent a subtle but significant change in how they related to patients. The rich, complex human beings they encountered in their first clinical experiences gradually became "cases"—collections of symptoms to be matched with diagnoses and medications. The residents didn't become uncaring. Many were deeply empathetic people who entered psychiatry precisely because they wanted to understand human suffering. But the system they trained within gradually taught them to set aside the dimensions of the patient's experience that didn't fit the diagnostic framework.

This process of translation has particular relevance for people whose distress has spiritual or existential dimensions. In a system organized around symptom checklists and medication algorithms, there's no place to record that a patient's crisis began with a mystical experience, that their voices feel meaningful rather than random, that their suffering seems connected to questions of purpose and meaning rather than neurochemistry alone. These dimensions of experience don't appear in the diagnostic categories, so they don't appear in the treatment plan. The patient learns—sometimes quickly, sometimes painfully—to present their experience in terms the system can recognize, editing out the parts that don't fit. Luhrmann's work reveals this editing process with heartbreaking clarity, showing how a system designed to help people can simultaneously silence the aspects of their experience that matter most to them.

Luhrmann's anthropological lens reveals something that most critiques of psychiatry miss: the psychiatric clinic is itself a cultural system with its own rituals, hierarchies, origin stories, and unexamined beliefs. The morning rounds, the case presentations, the diagnostic conferences—these aren't neutral scientific procedures. They're cultural practices that reinforce particular ways of understanding mental distress and exclude others. The language psychiatrists use to describe patients, the stories they tell about successful treatments, the implicit hierarchies of knowledge (brain scans are more authoritative than patient narratives, randomized controlled trials outweigh clinical experience)—all of these reflect cultural values that are invisible to participants but profoundly shape what kind of care gets delivered.

This cultural analysis is liberating because it denaturalizes what the psychiatric system presents as objective scientific truth. If the biomedical model of mental illness is partly a cultural product—shaped by economic forces, institutional structures, and philosophical assumptions about consciousness and the mind—then it's not the final word on human mental suffering. Other cultural frameworks, including the spiritual and transpersonal perspectives IMHU advocates for, aren't merely "alternative" views being measured against an objective standard. They're different cultural responses to the same fundamental human phenomena, each with its own insights and blind spots. Luhrmann doesn't make this argument explicitly—she's too careful an anthropologist to advocate openly—but the implication is clear. Once you see psychiatry as a culture rather than simply as a science, the door opens to asking which cultural assumptions serve patients well and which ones might need to change.

"Of Two Minds" was published in 2000, and the trends Luhrmann identified have only intensified since then. The biomedical model's dominance has grown, psychiatric training has become even more pharmacologically focused, and the space for understanding mental distress as anything other than brain malfunction has continued to shrink within mainstream institutions. At the same time, the model's limitations have become increasingly apparent. The promised revolution in psychiatric treatment based on neurobiological understanding hasn't materialized. Newer medications aren't dramatically more effective than older ones. Many patients remain chronically ill despite technically adequate pharmacological management. The field is beginning to acknowledge what Luhrmann's ethnography suggested two decades ago: that something important was lost when psychiatry abandoned its interest in the whole person.

For IMHU, Luhrmann's work provides something invaluable: a rigorous, non-polemical account of how the current psychiatric system came to be the way it is, and why it fails so many people whose experiences don't fit its categories. Understanding this history is essential for anyone trying to change the system, because effective advocacy requires knowing what you're up against—not just the scientific arguments for the biomedical model, but the institutional, economic, and cultural forces that sustain it. The book also offers hope, precisely because it reveals the contingency of the current paradigm. If the biomedical model's dominance was shaped by forces other than pure scientific evidence, then different forces—including the growing body of research on spirituality and mental health, the voices of people with lived experience, and the work of organizations like IMHU—might reshape the field again. What anthropology teaches us is that cultures change. Even the culture of psychiatry.
