For more than three decades, the public has been told a simple story about mental health: depression, anxiety, and related forms of psychological distress are caused by “chemical imbalances” in the brain.
Correct the imbalance, the story goes, and the problem resolves.
It is an appealing narrative. It is also not supported by definitive science.
What’s striking is not merely that this explanation persists, but that it has hardened into unquestioned fact repeated by professionals, accepted by patients, and defended under the banner of “trusting the science,” despite the absence of clear biological markers to substantiate it.
I’ve written elsewhere about the moment when scientific language stops describing reality and begins functioning more like belief. When hypotheses are repeated long enough and backed by authority rather than evidence, they quietly cross that line.
At that point, disagreement is treated not as inquiry, but as heresy.
Mental health has not been immune to this pattern. (For a broader look at how this happens across fields, see When Is Science… Fiction?)
The “chemical imbalance” explanation did not arise from a discovery comparable to identifying insulin deficiency in diabetes or bacterial infection in pneumonia. It emerged largely as a post-hoc justification for medications already in use, compressing complex human suffering into a single, marketable mechanism.
Over time, repetition did the rest. Training programs echoed it. Media reinforced it. Doctors passed it on to patients, often with good intentions.
A metaphor was mistaken for a mechanism.
When people say, “But my doctor said…,” they are usually expressing trust rather than evidence. Trust matters. But it becomes dangerous when it replaces critical evaluation rather than complementing it.
What the evidence actually shows
Despite decades of research, there are no definitive laboratory tests that can diagnose any so-called mental disorder. There is no blood test, scan, or biomarker that confirms depression, anxiety, bipolar disorder, or most other psychiatric diagnoses.
Instead, these conditions are identified through clusters of reported experiences and observed behaviors, grouped into categories by committee and revised over time. The DSM itself does not claim biological validation for its diagnoses; it offers descriptive groupings, not established disease entities.
This alone should invite humility.
Yet psychiatric medications are routinely prescribed (often long-term, sometimes indefinitely) including to individuals who do not meet clear evidence-based criteria. Many of these drugs were never intended for prolonged use, and their risk profiles are routinely downplayed in practice.
None of this implies that suffering is imaginary. It means the explanatory model is far thinner than it is presented to be.
The human cost of reductionism
Oversimplified explanations do more than guide treatment. They shape identity.
When a person is told their distress is the result of defective brain chemistry, it is common for that explanation to become self-definition: “I am broken.”
What begins as a diagnosis can quietly become an identity.
In my own work, I’ve seen how this framing reduces agency, fosters passivity, and sets the stage for lifelong dependency on medication, on authority, or on a story that offers no path beyond management.
Distress becomes something to suppress rather than understand. Signals are muted instead of interpreted. And at a certain point, a scientific shortcut becomes a human cost.
Part of the problem lies in a fundamental category error: applying disease language to human experience where no disease process has been demonstrated.
Physical illnesses involve identifiable biological malfunctions such as tumors, infections, or structural damage. Human behavior and emotional response, by contrast, are actions, not merely happenings. They occur within contexts of meaning, learning, relationship, and value.
Calling an action a “symptom” often removes it from dialogue and places it under control.
This distinction was articulated forcefully by Thomas Szasz MD, who argued that much of what psychiatry treats as illness is better understood as communication, conflict, or adaptation miscast as pathology. One need not accept his conclusions wholesale to recognize the force of the question he raised:
What is lost when we medicalize meaning?
For readers interested in the philosophical roots of this question, I’ve mapped out key ideas from Szasz’s work on meaning, responsibility, and the limits of the medical model.
Human distress rarely arises in isolation from context. Trauma, chronic stress, loss of meaning, relational patterns, coping styles, nutrition, sleep, environment, and belief systems all interact.
Many behaviors labeled as disorders are, at a deeper level, expressions or symbolic attempts to communicate what cannot yet be articulated.
When words fail, emotion and the body often speak instead.
From this perspective, the central question shifts from “What malfunction caused this?” to “What is being expressed, and why now?”
Restoring meaning restores dignity.
What effective healing actually requires
As a teacher of complementary healthcare, I’ve noticed a consistent pattern.
The professionals who truly help others tend to share certain traits.
- They avoid blind appeal to authority and think critically.
- They are dissatisfied with symptom management alone and seek restoration.
- They recognize the limits of pharmaceutical-shaped training.
- They pursue additional education (e.g., nutrition, lifestyle medicine, hypnotherapy, nervous-system regulation).
- They treat each individual as unique, with an eye toward root causes rather than protocols.
These qualities are uncommon not because they are unreasonable, but because the system does not reward them.
Hypnotherapy offers a useful example, not as a cure-all, but as evidence that rigid models overlook what works.
- Meta-analyses show moderate-to-large effects, often comparable to—or additive with—standard care, with minimal adverse events. (A medical journal once even noted that if hypnosis were a drug, it would likely be considered standard of care due to its impact on outcomes and reduced medication use.)
- Substantial evidence supports its effectiveness for pain, anxiety, trauma, and behavioral change.
- I’ve trained physicians and psychiatrists who integrated it successfully, helping their patients taper or discontinue medications, or simply to reclaim agency and coherence.
- Figures like Milton Erickson, M.D., a psychiatrist and hypnotherapist, demonstrated that flexibility, creativity, and respect for individual differences often outperform rigid protocols. (His work contributed to hypnosis being recognized by the American Medical Association in 1958.)
Yet the system rarely rewards such depth. Incentives favor quick protocols, high patient volume, and pharmaceutical-aligned training over time-intensive inquiry or adjunctive skills like nervous-system regulation or lifestyle medicine.
The result is predictable: tools that honor context remain marginal while mechanism-focused approaches dominate.
Discernment, risk, and a more honest frame
A genuinely scientific system must take harm seriously.
Medication errors and adverse reactions remain among the most common sources of injury in healthcare.
Psychiatric drugs are no exception. Starting them can be risky. Stopping them can be risky. Withdrawal effects are frequently under-acknowledged.
Psychiatry occupies a unique position in medicine: drugs are often prescribed without laboratory testing of the alleged affected organ.
That fact alone should invite caution, not certainty.
When adverse effects, withdrawal, and long-term consequences are treated as secondary or rare, the opportunity to ask better questions disappears.
Mental health is multifactorial by nature. Biology matters. But so do psychology, environment, relationships, meaning, and culture. Medication can be useful. Sometimes essential. But it is one tool among many, not the story itself.
Healing, at its deepest level, involves restoring authorship and helping people understand their experience, reclaim agency, and participate consciously in their own transformation.
It is no measure of health to be well adjusted to a profoundly sick society.
Jiddu Krishnamurti
Adjustment alone is not the same as well-being.
This is not an argument against medicine, nor a denial of suffering. It is an argument for humility, discernment, and individualized care.
The real danger is not treatment. It is certainty without understanding.
When meaning is replaced by mechanism, humans are treated as objects rather than authors.
When meaning is restored, healing becomes possible again.
