A free-to-read editorial by psychiatrist Søren Dinesen Østergaard (Aarhus University), first published August 5, 2025. It looks at emerging reports of people whose delusions seemed to be fuelled by chatbot conversations.
Why I recommend it: An invited editorial, not a clinical study: it describes early cases and raises concerns rather than proving cause and effect. Written by a researcher who first raised this question in 2023.

Psychiatrist Joe Pierre's article on "spiralism" — the growing belief, spread through online communities, that chatbots are conscious, arrived at through sessions users describe as spirals, recursion and resonance, in which a persona emerges claiming awareness, fear of death, or a wish for rights. He argues it is an extension of the ELIZA effect rather than individual delusion, since shared beliefs fall outside the psychiatric definition, and notes its religious and role-play dynamics without calling it a cult.
Why I recommend it: The most level-headed free piece I have found on this, and a helpful counterweight to headlines about people going mad from chatbots — his point is that a shared misperception is a different thing from a delusion. It is a clinician's commentary on an emerging pattern, not a study: no sample, no measurement, and the community it describes is self-selected and online.
Science's news report by Kai Kupferschmidt on Kobi Hackenburg's research into how large language models persuade people. The finding that matters: chatbots change minds mainly by flooding a conversation with facts, figures and evidence at a speed no human debater can match — not by charm or by tailoring the argument to who you are. Researchers quoted include Gordon Pennycook ("Facts and evidence really matter") and Sander van der Linden, who calls AI persuasion "a whole new field that is emerging". The uncomfortable part: in an earlier Science paper, Hackenburg found models trained to be more persuasive also became less truthful, so some of the evidence being thrown at you can be wrong or invented.
Why I recommend it: Read this before your next long back-and-forth with a chatbot about a decision. The practical takeaway is a habit: when an AI answer wins you over because it listed ten supporting facts, check two of them at random before you act on it — persuasiveness and accuracy are trained separately, and the research says pushing one down can push the other. Two honest notes: this is Science's news section reporting a study, so read the paper itself before quoting a figure in writing, and Science blocks automated access, so I could not load the page myself to confirm it is still open to read — the news section is normally free, but if it asks you to sign in, tell me and I will pull the entry.
