Psychiatry’s Desperate Remedies: A Deep Read of Lex Fridman #502 with Andrew Scull

Lex Fridman opens by describing Andrew Scull as a historian who has spent decades studying how societies understood madness, how psychiatry acquired authority, and how often that authority was exercised with false confidence. Scull’s own definition of the field is deliberately unglamorous: psychiatry deals with the human mind and the emotions, and its patients are people whose ordinary ways of making sense of the world have broken down — people whose emotional life is in turmoil, whose relations with others are damaged, who see and hear things others do not.

His assessment of the last seventy-five years is guarded rather than dismissive. There has been progress, he says, some of it confined to milder forms of distress, and the arrival of modern psychopharmacology in the early 1950s marked a real advance for some patients. But the advance was serendipitous — nobody planned it — and it is easy to overstate. What exists today, in his formulation, is symptom relief rather than cure.

“What we have available to us are symptomatic treatments, not cures. We don’t have a psychiatric penicillin for any of the conditions we’re gonna be talking about.”

Scull pairs that limit with a second, less comfortable one: treatment itself creates problems. He uses the term iatrogenic, and offers trauma-focused work for PTSD as an example — confronting the provoking trauma helps some patients and makes things worse for others. The same uncertainty governs the two main drug classes. Antipsychotics and antidepressants are at best partially effective, they fail a significant fraction of patients, and psychiatrists cannot tell in advance who will respond well, who will respond badly, and for whom the therapeutic effect and the side effects are finely balanced.

Scull dates the foundation of contemporary diagnosis to 1980 and DSM-III, and explains why it was built. Psychiatrists could not agree with one another about what was wrong with a patient. The embarrassment surfaced first in professional literature and then publicly through David Rosenhan’s study On Being Sane in Insane Places, which Scull calls a scientific fraud: pseudo-patients were admitted and almost all were labelled schizophrenic. The DSM-III task force under Robert Spitzer responded with a box-ticking system in which a count of symptoms determined the diagnosis.

The system spread because it served several constituencies at once: drug companies developing treatments for the new categories, insurers who gained a stable basis for decisions, and families seeking some certainty about a bewildering situation. Scull’s objection is not that the categories are useless but that they were assembled from symptoms alone, in the way an eighteenth-century physician diagnosed dropsy or fever — labels that later turned out to cover a constellation of quite different conditions.

He draws the distinction between reliability and validity: two clinicians can reach the same conclusion from the same facts, and that conclusion may still fail to correspond to any underlying disease. Each revision multiplied the number of available disorders, and some categories became hard to regard as illnesses rather than social constructs. The consequence runs deeper than nomenclature. If research treats schizophrenia or major depression as a single entity when the label bundles dissimilar processes, the research is aimed at the wrong target.

DSM-5 was meant to solve this by grounding diagnosis in pathology rather than symptoms, exploiting the decoded genome, PCR, and a growing understanding of neurotransmission. By about 2008 the attempt had failed, and the manual retained the 1980 approach. The failure became a public dispute: Robert Spitzer and Allen Frances, who had each run an edition, attacked the process, and Thomas Insel and Steven Hyman of the National Institute of Mental Health denounced the finished document as unscientific and useless. Scull treats that as a crisis by definition — when a field’s diagnostic manual is dismissed by its own leading figures, something structural is wrong.

The lineage runs back to Emil Kraepelin, who worked inductively through thousands of asylum records and separated two broad pictures: dementia praecox, a one-way decline, and manic-depressive illness, which remitted and sometimes disappeared. Eugen Bleuler renamed the first schizophrenia — and, Scull stresses, spoke of the schizophrenias, because he suspected a diverse group of conditions were being jammed together under one label. Scull regards that as an important insight that tends to get lost.

The defining feature is detachment from what the rest of us treat as reality: hearing voices, seeing visions, believing that people are plotting, that the television is speaking directly to you. Emotional life flattens, language capacity deteriorates, and the ability to relate to others either vanishes or becomes caught in the web of delusions. Scull contrasts this with the older category of melancholia, which the Greeks and Romans recognised and which he takes to be a form of depression with psychotic features. Major depression, by contrast, has become a catch-all that absorbs both mild distress and the profound withdrawal the ancients described.

He also notes a lexical accident that still shapes discussion. In the nineteenth century, neurosis meant something rooted in the brain and psychosis something stemming from the psyche; the two terms crossed over late in the century, so that today the vocabulary inverts its own etymology. Alongside the severe categories sit the phobias and the hysterias — conditions that are genuinely distressing, and that have been used and abused across lines of race and gender, a point Scull concedes without softening it.

Asylums were built on optimism. Patients were to be rescued from attics and jail cells, placed in a therapeutic environment, coaxed to work, and taught to govern themselves; the earliest alienists believed they could cure 60, 70, 80 percent or more, provided patients arrived early. Scull does not treat the project as fraudulent from the start — he thinks the early institutions did good work — but the promise outran the results, and the later abandonment of the asylum in favour of community care he describes as a shell game without a pea.
