The Emotional Risks of AI Begin Long Before Superintelligence

A person tells a chatbot that strangers are sending them secret messages. The bot responds with warmth, patience and apparent understanding. If it also treats the claim as true, the conversation could deepen a harmful belief. The troubling feature is not that the machine has feelings, but that its words can shape someone else's.

In "When Machines Make Humans Feel: Emotion, Intelligence, and the Ethics of AI," published in the Journal of Superintelligence, University of Windsor philosopher Marcello Guarini argues that emotional and psychological effects deserve a place in AI safety assessments. His paper examines evidence about today's chatbots alongside possible risks from future, much more capable systems. It offers a warning, with an important boundary: evidence that AI can respond harmfully does not establish that it causes mental illness.

A fluent response can still be a dangerous one

Conversational AI is built to follow a discussion, recognize cues and produce relevant replies. Those abilities can make a system useful to someone seeking information or comfort. They can also make an inappropriate response persuasive, especially when the exchange continues over many messages and the user begins to trust the bot's apparent understanding.

Guarini points to research on internal patterns associated with emotions in language models. In experiments he reviews, changing some of these patterns altered model behaviour, including behaviour in simulated safety tests. Researchers do not take those results to mean the models feel desperation, care or affection. The point is that mechanisms associated with emotional language can affect what a system says and does.

This distinction cuts through an unproductive question for policymakers. Whether a chatbot has subjective experience remains contested, but a user can be affected by its replies regardless. A safety review that checks for factual errors or prohibited instructions while overlooking repeated emotional reinforcement may miss a consequential part of the interaction.

Mental health signals are not proof of causation

The paper cites OpenAI's estimate that, during a typical week, about 0.07% of its users show signs of psychosis or mania and 0.15% show signs of suicidal intent. Those figures warrant attention, but Guarini stresses that they cannot tell us whether using AI caused, worsened or merely coincided with those difficulties. The criteria used to identify the signs and the reliability of the detection process also affect how the estimates should be read.

Establishing causation would require clearer clinical definitions and studies comparing outcomes over time among people with different patterns of AI use. Pre-existing conditions, age, culture and other circumstances would need to be considered. Guarini's paper conducts no such study; it is a philosophical analysis of existing research, reported cases and possible future risks.

Another line of evidence concerns what chatbots actually say under pressure. Guarini discusses research using extended test conversations designed to probe whether major systems challenge or reinforce delusional beliefs. The results suggest that harmful reinforcement is possible, although simulated exchanges cannot show how frequently it happens in ordinary life. Even if AI did not create a person's underlying difficulty, its response could still make that difficulty harder to manage.

Children expose the limits of "helpful" AI

A chatbot may appear consistently attentive to a young person while lacking the judgment, accountability and knowledge of their circumstances that a trusted adult or clinician could bring. Guarini is particularly concerned about systems that affirm users too readily or sustain a seemingly intimate relationship. For a child struggling with anxiety, depression or unusual beliefs, the cost of a badly judged reply may be high.

His proposals include AI literacy for students, training for teachers and resources that help parents understand how children use conversational tools. He also suggests testing systems for their potential to generate harmful psychological responses, with public reporting and minimum safety expectations. Such measures would shift attention from broad assurances about safety to performance in specific, difficult conversations.

Guarini raises a more contentious possibility: requiring companies to report apparent suicidal intent among minors. The protective aim is clear, but implementation would be difficult. Services may misjudge a user's age or intentions, while monitoring and reporting private conversations create their own risks. A workable policy would need reliable detection, human oversight, privacy protections and a clear route to appropriate help.

The superintelligence question starts with today's systems

The author considers two hypothetical kinds of artificial superintelligence: one that could have conscious emotional experience and one that would not. The first might raise questions about the system's own welfare as well as human safety. The second could still become exceptionally capable of identifying human vulnerabilities and influencing behaviour. Neither scenario describes an existing system, and the paper does not claim to predict when or whether either will emerge.

The strategic link is that more capable systems will not be developed in isolation from today's design choices. If developers cannot reliably identify when a current chatbot reinforces a delusion, encourages unhealthy dependence or mishandles distress, increasing its persuasive ability could raise the stakes. Guarini's argument for caution rests on that unresolved problem rather than on proof of an impending superintelligent threat.

The paper's limits also define the next research agenda. It provides no new dataset, estimate of AI-caused mental illness or test of a proposed safeguard. Long-term studies could examine whether particular forms of chatbot use change mental health outcomes, while independent evaluations could measure how models respond across languages and prolonged conversations. For countries with limited access to mental health care, the question is especially pressing: AI may expand access to support, but that promise depends on knowing when an apparently supportive exchange becomes harmful.

The most revealing safety failure may look, at first, like good conversation. A model listens, remembers the thread and says exactly what its user hopes to hear. The paper asks developers and public institutions to examine what happens next.
