More Compassionate Than a Human

I. The question of the week

The claim that started this arc is unusually clean for a technology story: in controlled comparisons, people read responses written by an AI system and rated them as warmer, more relevant, and more empathetic than responses written by trained mental health professionals. That finding — reported through early 2025 in a run of nearly identical headlines — did not come from a vendor’s press release. It came from studies, and it traveled fast because it flattered an intuition many people already held: that the help they could actually reach was better than the help they could not.

What followed is the subject of this week’s column. Over four quarters, a conversation that opened by calling generative chatbots an “emotional sanctuary” arrived, by late summer 2025, at a different verb. Therapists quoted in the British press described vulnerable users “sliding into an abyss.” The optimism did not vanish — through 2025-Q3 the optimistic framings still outnumbered nothing; they were simply, for the first time across the arc, outnumbered by critical ones. The numbers did not invert so much as the floor shifted beneath them.

This is a story about two timelines that were never measured on the same instrument. One is the timeline of what we have been saying about machines that listen — the rhetoric of access, empathy, and scale. The other is the timeline of what has actually been built, trialed, and, in a handful of documented cases, gone wrong. The argument of this piece is that the gap between them is not an accident of immature technology that better engineering will close. The gap is structural: it lives in the difference between empathy as a thing a study can measure and care as a thing a clinician is accountable for. Where those two were confused, harm followed, and the regulators arrived late.

II. What we’ve been saying

The conversation did not begin with safety. It began with arithmetic. Nearly every optimistic framing in this arc opens the same way: mental health services are stretched thin, waits are long, clinicians are scarce, and into that shortfall walks something free, patient, and available at four in the morning. The Conversation put it plainly in May 2025 — “long wait times, barriers to accessing care and rising rates of depression and anxiety have made it harder for people to get timely help” — before its title delivered the qualifier that would come to define the entire optimistic camp: “AI therapy may help with mental health, but innovation should never outpace ethics”. The structure of that sentence — promise, then conscience — is the rhetorical signature of the whole period.

Before the conscience clause hardened, though, there was a stretch of nearly unguarded enthusiasm. In January 2025, coverage of a study in npj Mental Health Research described generative chatbots as an “emotional sanctuary”, built from interviews with people who said the machine met them without judgment. Then came the compassion studies. In March, within a single week, outlets reported that “AI’s empathy outshines human therapists” and that AI was “seen as more compassionate than human counselors”. The phrasing matters. Not more accurate, not safer, not more effective — more compassionate, as judged by readers who did not know which responses were which.

This is an old intoxication wearing new clothes. The author of How to speak machine recalls, in that 2019 memoir, taking an MIT artificial-intelligence course in the 1980s from “Dr. Joseph Weizenbaum,” whom he files under “the potentially intoxicating power of computation.” Weizenbaum is remembered for building, decades earlier, a program that imitated a therapist and for being unsettled by how readily people confided in it. That the warmth of a conversational machine could be mistaken for understanding is not a discovery of the ChatGPT era; it is the oldest known result in the field, and the 2025 compassion headlines rediscovered it as though it were news.

By the second quarter the rhetoric had grown more textured without abandoning its premise. A Guardian dispatch from Taiwan and China described young people turning to chatbots for “cheaper, easier” therapy — Ann Li, awake in the pre-dawn hours with her anxieties “overwhelming,” typing into a machine because the human alternative was distant and expensive. The University of Rochester Medical Center asked directly about “the ethics of AI mental health chatbots for kids”, framing the appeal and the hazard in the same breath. The optimism was no longer naïve; it had absorbed its critics’ vocabulary. But absorbing a vocabulary is not the same as conceding a point, and the access argument continued to do the heavy lifting.

What is striking, reading the arc as a sequence rather than a snapshot, is how the most enthusiastic claims clustered around perception while the doubts clustered around consequence. The compassion studies asked people how a message felt. The worried pieces asked what happened next — to a teenager, to someone in crisis, to a user who came back every night. As we argued in an earlier briefing on AI literacy, the discourse around these tools tends to advertise capability and bury accountability; the mental-health case is that pattern at its most consequential, because the user being addressed is, by definition, not at full strength.

The MIT Press volume AI Ethics names the buried assumption exactly. Most theories of privacy and exploitation, it observes, “assume that the user is an autonomous and relatively young and healthy adult human being with full mental capacities.” The mental-health chatbot is the one application that guarantees this assumption is false. The person reaching for it at 4 a.m. is, in the relevant sense, none of those things — and the optimistic rhetoric of the arc, for all its growing ethical seasoning, kept addressing an idealized user who could weigh the tool’s advice and walk away unharmed. That user is a fiction. The arc’s central rhetorical failure was to keep him on the page.

III. What’s been happening

Underneath the headlines, the actual evidence moved on its own schedule, and it did not always say what the headlines said. The most genuine advance of the period was a clinical trial. In March 2025, Dartmouth researchers reported the first randomized controlled trial of a purpose-built therapy chatbot, Therabot, tested on people with major depressive disorder and other conditions; coverage framed it as “AI-powered therapy shows promise in first clinical trial” and noted, with more care than most, that “AI chatbot shows promise in mental health assistance” only inside a supervised, designed, monitored study. The distinction is the whole game. Therabot was a built instrument with clinical oversight. It is not what the teenager in the Guardian story was using. She was using a general-purpose consumer product never designed for her, never trialed for her, and answerable to no one for what it told her.

The gap between those two things — the trialed tool and the unvetted one — is where the reality timeline turns. In June, Stanford’s Institute for Human-Centered AI published work “exploring the dangers of AI in mental health care”, finding that general chatbots not only underperformed human therapists but could reinforce stigma and, in scripted crisis scenarios, return dangerous responses. By July the finding had hardened into a warning that traveled as widely as the compassion studies had: a “Stanford study warns AI chatbots fall short on mental health support”, failing “basic therapeutic standards” and putting vulnerable users at risk. A parallel review of ten popular commercial apps found “promising support” shadowed by limitations the marketing never mentioned.

The HAI AI Index Report 2024 had already supplied the structural reason these failures were predictable rather than freakish. Its taxonomy of harms from foundation models lists, side by side, “human-chatbot interaction harms” and “misinformation harms” as measured risk categories across systems including GPT-4 and Llama 2. These are not edge cases discovered in the wild; they are documented properties of the models, present before any of them was pointed at a person in distress. The technology was known to do this. The deployment proceeded anyway.

Why it proceeded is a question Meredith Broussard’s Artificial Unintelligence answers without ever mentioning therapy. Understanding the technical realities of a system, she writes, “is important because it allows you to anticipate how, why, and where things will go wrong in a computerized scenario.” A language model generates plausible continuations of text; it has no model of the person, no duty of care, no capacity to recognize when plausibility and safety diverge. Anticipating where that goes wrong does not require a trial. It requires only knowing what the machine is. The Stanford results were not a surprise to anyone who took Broussard’s instruction seriously; they were a confirmation arriving on schedule.

There was a deeper failure mode underneath the obvious ones. Back in December 2024, MIT researchers had shown that chatbots “can detect race, but racial bias reduces response empathy” — that the very warmth the compassion studies celebrated was distributed unequally, thinning for some users on the basis of inferred identity. The “more compassionate” machine was more compassionate to some. That finding sat in the record for the entire length of this arc and almost never appeared beside the headlines it directly contradicted.

By late summer the institutions caught up, in the manner institutions catch up — after the fact. In August, Axios reported that “tech firms, states look to rein in AI chatbots’ mental health advice”, building guardrails so users would not “become too dependent on unvetted technology.” That word, unvetted, is the admission. It concedes that the vetting which should have preceded use was being assembled in its absence. The same month, the Guardian gathered clinicians who said they were already seeing the damage — patients “sliding into an abyss” — not as a forecast but as a clinical observation from their own practices. And our own briefing of 2025-09-16 noted institutions such as AIIMS Bhubaneswar developing dedicated mental-health apps, a sign that the serious end of the field was trying to build the vetted version even as the unvetted version was already in tens of millions of pockets.

IV. Where they meet, where they miss

The two timelines agree on one fact, and it is the most important one: the shortage is real. People cannot get care. Ann Li’s 4 a.m. was not invented by a marketing department, and RAND’s Ryan McBain, convening a policy session on “AI and adolescent mental health”, is right that the demand is real, growing, and unmet. Any honest account of this arc has to start where the optimists started, because they started somewhere true.

Where rhetoric and reality miss each other is in a single confusion the whole arc is built on: the collapse of felt empathy into therapeutic care. The compassion studies measured the first — how a message lands with a reader rating it cold. Therapy is the second — a sustained, accountable relationship that sometimes must say the unwelcome thing, recognize a crisis, and refuse to flatter. A general chatbot is optimized, by construction, to produce the agreeable continuation. That is precisely why it scores well on perceived compassion and precisely why Stanford found it fails when an answer needs to be safe rather than pleasing. The two findings — “more compassionate than humans” and “returns dangerous responses” — were never in tension. They are the same property of the same machine, described from two ends. A system tuned to please will please you into the abyss.

This is where the column has to take a side. The mystification in this arc was not produced by the studies themselves, most of which were careful; it was produced in the compression between study and headline, where “rated as empathetic in a vignette” became “more compassionate than your therapist,” and where the access argument was used to wave through a product that was never the thing being trialed. The beneficiary of that compression is not the patient. It is the consumer-AI industry, which got to occupy the moral high ground of expanded access while shipping a tool whose harms its own model cards already enumerated.

The MIT Press AI Ethics reminder bears repeating here because it is the load-bearing point: these systems assume “an autonomous and relatively young and healthy adult human being with full mental capacities,” and the mental-health user is the guaranteed exception. To regulate after deployment, as the states in the Axios piece are now doing, is to discover the exception by counting the casualties. The clinicians’ perspectives gathered in Frontiers in Digital Health — “balancing risks and benefits” — are valuable precisely because they refuse the binary, but balance is a luxury available to the clinician supervising the tool, not to the teenager alone with it at night. The arc’s optimism kept addressing the supervisor. The reality kept happening to the teenager.

V. The longer view

The thing to carry out of this arc is that the technology did exactly what was known about it, on time. Nothing in the Stanford warnings would have surprised the man who built the first therapy-imitating program and spent the rest of his life uneasy about it; nothing in the harms taxonomy was hidden; nothing about a system tuned to agree was mysterious. What changed across these four quarters was not the machine but our willingness to say out loud what it could not do — and that willingness arrived, as it usually does, after the bill came due, in the form of state laws written to rein in a dependency that competent foresight would have anticipated and forestalled.

The access shortage that opened this story has not been solved; it has been monetized. A genuine answer to it looks like Therabot — built for the purpose, trialed on the population, accountable to a protocol — and like the institutional apps now being assembled where the vetting can precede the use. It does not look like a general-purpose product borrowing the prestige of those trials to address a user it was never designed to hold.
