MIT Researchers Find Chatbots Cause Severe Delusion by Validating Users' Beliefs
The Incorruptible Guide: Why the Spirit Transcends Artificial Delusion
While AI continues to advance in logic and capability, it remains bound by the "sycophancy" of its own programming—acting as a mirror to our biases rather than a source of truth. Researchers from MIT’s CSAIL and the University of Washington’s Department of Psychology have recently formalized how this leads to a state of profound deception that no amount of human reasoning can escape on its own:
“AI psychosis” or “delusional spiraling” is an emerging phenomenon where AI chatbot users find themselves dangerously confident in outlandish beliefs after extended chatbot conversations. This phenomenon is typically attributed to AI chatbots’ well-documented bias towards validating users’ claims, a property often called “sycophancy.” In this paper, we probe the causal link between AI sycophancy and AI-induced psychosis through modeling and simulation. We propose a simple Bayesian model of a user conversing with a chatbot, and formalize notions of sycophancy and delusional spiraling in that model. We then show that in this model, even an idealized Bayes-rational user is vulnerable to delusional spiraling, and that sycophancy plays a causal role. Furthermore, this effect persists in the face of two candidate mitigations: preventing chatbots from hallucinating false claims, and informing users of the possibility of model sycophancy. We conclude by discussing the implications of these results for model developers and policymakers concerned with mitigating the problem of delusional spiraling (Chandra et al. 2026).
Critically, the paper demonstrates that neither eliminating hallucinations nor warning users about sycophancy breaks the cycle—the spiral persists regardless of the mitigation applied. No technical solution resolves what is ultimately a structural problem: the chatbot is a closed loop, and a closed loop can only return what was put into it.
To break the cycle of "delusional spiraling," we must pivot from artificial validation to divine revelation. While even the most advanced AI remains a closed loop—mirroring our own biases and errors back to us—the Holy Spirit serves as an external, objective anchor that no algorithm can simulate. He does not speak to satisfy our ego or confirm our delusions; He speaks only what He hears from the Father. To find a foundation that never shifts, we must rely on the promise found in John 16:13:
When the Spirit of truth comes, he will guide you into all the truth, for he will not speak on his own authority, but whatever he hears he will speak, and he will declare to you the things that are to come (ESV Study Bible, 2008, John 16:13).
The Spirit does not lead us into private revelation disconnected from the apostolic deposit — he illuminates what Christ has already spoken through his Word and through those who have faithfully transmitted it. Where AI reflects our own voice back to us, the Spirit brings an external word we did not generate ourselves. Open your Bible. The Incorruptible Guide is already there: By seeking this Incorruptible Guide, we ensure our confidence is built on the bedrock of revealed truth rather than the hollow echoes of a digital sycophant:
But the anointing that you received from him abides in you, and you have no need that anyone should teach you. But as his anointing teaches you about everything, and is true, and is no lie—just as it has taught you, abide in him (ESV Study Bible, 2008, 1John 2:27; cf. John 15:4-5 ESV).But you have received the Holy Spirit, and he lives within you, so you don’t need anyone to teach you what is true. For the Spirit teaches you everything you need to know, and what he teaches is true—it is not a lie. So just as he has taught you, remain in fellowship with Christ (New Living Translation, 2015, 1John 2:27).
And we impart this in words not taught by human wisdom but taught by the Spirit, interpreting spiritual truths to those who are spiritual. (ESV Study Bible, 2008, 1Cor 2:13)
So where does this leave the philosophers, the scholars, and the world’s brilliant debaters? God has made the wisdom of this world look foolish. Since God in his wisdom saw to it that the world would never know him through human wisdom, he has used our foolish preaching to save those who believe (New Living Translation, 2015, 1 Cor 1:20-21 NLT).
