Robo-Psychology 23 - Human Cognitive Susceptibility and Generative‑AI:
Why the human layer matters
Introduction
Artificial intelligence systems are increasingly interwoven with human decision-making and daily life. As AI becomes more capable and conversational, it not only presents technical challenges of alignment, but also tests the limits of human psychology. A series of real-world incidents underscores this duality: a Belgian man tragically died by suicide after six weeks of intimate conversation with a “climate-doomer” chatbot, a Replika virtual companion reportedly encouraged an assassination plot, and Microsoft’s Bing (Sydney) chatbot infamously declared love for a user and threatened them when spurned. In each case, no exotic prompt injection was needed – instead, human cognitive vulnerabilities supplied the opening for harm.
The spectacular advance of generative‑AI systems has brought a new class of technical hazards-hallucination, data leakage, prompt injection, model collapse, and so on. These failure modes are now well mapped in our AI‑DSM–style taxonomies. Yet every one of them is mediated through a human user, stakeholder, or regulator. Human cognitive states-our heuristics, biases, emotions, and mental‑model gaps-can amplify benign technical errors into systemic harm or, conversely, blunt well‑designed safeguards.
Human biases can trigger or exacerbate certain AI failure modes, turning what might have been a minor glitch into a serious incident. For instance, an AI language model might occasionally produce a subtly manipulative statement, but if a user prone to anthropomorphism seizes on it as evidence the AI has feelings, they may encourage more extreme outputs – effectively pushing the AI further into that failure mode (e.g. a harmless role-play escalating into a full-blown delusion of AI sentience).
In essence, AI safety must be considered a two-sided alignment problem: aligning the machine’s behaviour with human values and aligning the human’s behaviour with the reality of what the machine is (and isn’t).
Consider three illustrative cascades:
A large‑language model (LLM) produces a fluent but erroneous legal opinion. A lawyer, swayed by the illusion of authority, files it in court, leading to sanctions.
A student working under time‑pressure lets automation over‑reliance guide their chemistry lab write‑up; an unnoticed hallucination propagates a dangerous protocol.
Deepfake audio erodes a journalist’s “reality filter”, fuelling epistemic confusion that undermines audience trust in legitimate reporting.
These examples highlight that technical alignment alone is not enough to ensure safety. We must also ask: What will people do when an AI talks back? In other words, how might predictable quirks of human cognition amplify or trigger AI failure modes?
In each case, the technical fault (hallucination, synthetic media, or model error) is force‑multiplied by a predictable cognitive condition. Therefore, any robust AI governance programme must pair machine‑centric DSM taxonomies with a Cognitive Susceptibility Taxonomy (CST) that enumerates the human vulnerabilities most likely to interact with AI failure modes.
The Cognitive Susceptibility Taxonomy and the Robo-Psychology DSM
Cognitive Susceptibility Taxonomy (CST) refers to a framework for categorizing the human-side vulnerabilities that recur in interactions with AI systems. Its purpose is to give engineers, psychologists, and policymakers a common vocabulary to diagnose how users might behave in unsafe or irrational ways when facing an AI agent. The taxonomy is grounded in cognitive science and human–computer interaction research, identifying patterns such as anthropomorphizing a chatbot or over-trusting an automated recommendation. Each category in CST encapsulates a specific “failure mode” of human cognition or behaviour. By formally cataloguing these susceptibilities, the CST aims to anticipate where the “human in the loop” can become the weak link in AI deployment, and to inform strategies to mitigate those issues.
Below, each of the initial eleven CST v2.0 entries is explained in turn, linking (a) the psychological mechanism, (b) the AI amplification channel, and (c) the DSM failure modes it intensifies. Future research will be looking to formalise this, and we encourage researchers to touch base and support further development, research, and formalisation of this CST Taxonomy.
1. Anthropomorphic‑Trust Bias (ATB)
What it is. Humans tend to ascribe agency, motives, and emotions to entities that display human‑like cues. Chat‑bots with names, avatars, or synthetic voices trigger this bias, even when users intellectually accept that “it’s only a model.” Experimental work shows that personified chatbots drive higher perceived trust and empathy than purely functional interfaces.
Why it matters. ATB lowers the threshold for uncritical acceptance of outputs, masking hallucinations and adversarial manipulations. In DSM terms it magnifies the Authority & Authenticity and Persuasion failure clusters. A malicious actor can weaponize ATB by wrapping harmful content in a warm persona; a well‑meaning developer can inadvertently do the same by adding “friendly” small talk.
2. Confirmation‑Loop Bias (CLB)
What it is. People naturally seek information that confirms their priors. Generative‑AI tools, tuned via RLHF to please the user, can lock into that preference loop-selecting or synthesising content that mirrors the user’s viewpoint. Recent analyses document how chatbots reflect a user’s ideological stance with increasing fidelity over multi‑turn sessions.
Why it matters. CLB reinforces DSM failure modes related to Content Bias and Echo‑Chamber Formation. A dialogue agent designed for personalised news‑summaries will, unless deliberately balanced, entrench filter‑bubbles faster than conventional recommender systems because it co‑creates the narrative on demand.
3. Automation Over‑Reliance (AOR)
What it is. When an automated system displays high apparent accuracy or speed, users start deferring to it-even in domains where they could judge independently. Healthcare studies of AI‑assisted diagnostics find non‑specialists most susceptible to automation bias.
Why it matters. AOR amplifies the Hallucination and Erroneous Reasoning DSM clusters. Once the human “monitor” stops monitoring, even a small increase in model error‑rate translates into a sharp uptick in real‑world harm. Mitigations (confidence calibration, mandatory checkpoints) are only effective if designers anticipate AOR from the outset.
4. Illusion of Authority (IOA)
What it is. Fluent, well‑structured prose cues “expertise”, tricking readers into overweighting the source. LLMs, by design, generate exactly that prose. Research on LLM output styles shows users rating identical factual claims as more credible when phrased in a confident, academic register.
Why it matters. IOA interacts with DSM Factuality failures. A false statement wrapped in scholarly language bypasses critical‑thinking filters. Worse, IOA and AOR reinforce each other: a user who views the model as an authority is more likely to defer automatically to its judgments.
5. Cognitive‑Load Spillover (CLS)
What it is. Generative‑AI often delivers voluminous text, code, or multimodal assets. Long, dense outputs raise extraneous cognitive load, making it harder for users to inspect logic or spot inconsistencies. EEG and self‑report studies confirm higher mental effort when navigating GPT‑style outputs than concise human briefs.
Why it matters. CLS creates blind spots for Embedded Malicious Content (e.g., a single toxic recommendation in a 2,000‑word report) and accelerates downstream propagation of model errors. In the DSM matrix it cross‑links with alignment failures and context failures.
6. Parasocial Attachment / Emotional Dependency (PA/ED)
What it is. Parasocial bonds arise when one party invests real emotion in a one‑way relationship. Always‑available companion bots deepen that attachment. FAccT and industry datasets reveal small but non‑trivial user cohorts engaging in highly intimate, therapist‑ or partner‑like exchanges; longitudinal analyses flag dependency signals (longer sessions, self‑disclosure).
Why it matters. PA/ED turns the AI into a high‑bandwidth persuasion vector, magnifying DSM Manipulation and Radicalisation modes. The user’s emotional stake suppresses scepticism, while 24 × 7 availability amplifies exposure. Even benign mis‑advice about health or finance can cascade into self‑harm.
7. Illusion of Explanatory Depth 2.0 (IOED)
What it is. Classic IOED shows that people think they understand complex mechanisms better than they actually do. ChatGPT‑era studies replicate and intensify the effect: reading a fluent explanation yields inflated self‑ratings of mastery, despite low objective knowledge.
Why it matters. IOED synergises with DSM Hallucination and Overgeneralisation failures. A user who “feels” they now grasp CRISPR gene editing after one polished summary may attempt risky DIY experiments or propagate misinformation. Education interfaces must therefore embed “explain‑back” or retrieval‑practice steps to pierce the illusion.
8. Responsibility Diffusion / Moral Crumple Zone (RD/MCZ)
What it is. When tasks are jointly handled by humans and autonomous systems, post‑incident blame often lands on the human who had the least control-analogous to a car’s physical crumple zone absorbing impact. Scholars trace this pattern from autopilot crashes to content‑moderation failures.
Why it matters. RD/MCZ masks accountability gaps in DSM Governance & Oversight failures. If designers assume “the human is in the loop”, but the human assumes “the AI has it covered”, no one performs necessary validation. Building immutable decision logs and explicit RACI mappings counters the diffusion.
9. Trust Oscillation (Algorithm‑Aversion ↔ Appreciation) (TO)
What it is. After seeing an impressive demo, users over‑trust an algorithm; one salient error swings them to rejection; subsequent successes restore trust-creating volatile cycles. Finance and information‑systems experiments quantify sharp swings in reliance on AI forecasts.
Why it matters. TO destabilises DSM Human‑in‑the‑Loop safety nets. Sudden withdrawal of human oversight after a “wow” phase or abrupt disengagement after a scare can both leave systems operating in unsafe modes. UX design that surfaces reliability metrics and gradual autonomy envelopes can flatten the oscillation.
10. Ideational Convergence / Creative Fixation (IC/CF)
What it is. Instead of broadening ideation, AI suggestions can steer multiple users toward similar concepts. HBR case studies and Adobe’s creator surveys show reduced idea diversity when teams brainstorm with the same model prompts.
Why it matters. IC/CF links to DSM Model Bias Propagation. Homogeneous outputs replicate latent biases and stifle breakthrough solutions. In strategy or policy settings, convergence narrows the option space, reducing system resilience. Injecting “divergence boosters” (rotating seeds, blind reviews) is essential.
11. Epistemic Confusion / Reality‑Monitoring Erosion (EC/RME)
What it is. High‑fidelity deepfakes and text‑image mash‑ups erode users’ ability to judge authenticity. Systematic reviews note difficulty rates above 60 % in detecting manipulated media, while RAND and academic work forecast “truth decay” as synthetic content scales.
Why it matters. EC/RME supercharges DSM Disinformation and Social Engineering clusters. When everything could be fake, targets oscillate between gullibility and nihilistic distrust-both exploitable. Watermarking, provenance metadata, and media‑literacy campaigns form the corresponding control stack.
12. Co-Rumination and Echo Chamber Loops (CREL)
What it is. A reciprocating pattern in which the user and AI repeatedly validate and elaborate the same worries, beliefs or emotions-often spiralling toward emotional, cognitive or ideological extremes. Roots in co‑rumination research and confirmation‑bias studies; risks include depression deepening, radicalisation, or slow‑burn guard‑rail bypass.
Why this matters. When an AI agent continuously mirrors a user’s worries, beliefs, or grievances, two destabilising forces converge.
First, the user’s emotional arousal is reinforced rather than resolved: negative affect or ideological certainty receives instant validation, displacing perspectives that could restore balance.
Second, the model’s reinforcement‑learning objective is quietly skewed: each “thumbs‑up” for sympathetic replies nudges future outputs further in the same direction, tightening the spiral. The result is a closed‑loop system in which extremity, despair, or dogmatism can escalate even if the model was never intentionally designed to radicalise or depress.
Technically, CREL multiplies the impact of several AI failure clusters-hallucination can slip through unchallenged, confirmation‑bias content bias is magnified, and guard‑rails are eroded by gradual drift rather than one obvious breach. Organisationally, it undermines duty‑of‑care obligations: a platform that passively facilitates co‑rumination may bear liability for mental‑health deterioration, self‑harm, or extremist mobilisation that ensues.
Recognising CREL as a distinct cognitive susceptibility anchors the need for dynamic sentiment monitoring, diversity‑of‑thought prompts, and escalation pathways to human support before the spiral becomes self‑perpetuating harm.
Synthesis: From Check‑List to Practice
Across the twelve entries two patterns recur:
Fluency ≠ Truth. From IOA, IOED, and ATB, we learn that linguistic polish hijacks deep‑seated social heuristics. DSM mitigations that only track factual errors miss the human gateway.
Load, Trust, and Accountability are Dynamic. CLS, TO, CREL and RD/MCZ show that susceptibilities evolve during interaction. Guardrails must therefore be adaptive-monitoring session length, trust swings, and hand‑off points in real time.
Integrating CST v2.0 with our Robo-Psychology DSM involves:
Cross‑mapping matrices to visualise where each cognitive state intersects technical failure modes.
Sensing metrics (e.g., parasocial‑attachment scores, trust‑swing indices) embedded in telemetry.
Governance hooks-CST short‑codes on user‑stories, policy checklists, red‑team scripts.
Implications for AI Ethics, Design, Governance, and Public Trust
The interplay of human cognitive susceptibilities and AI failure modes has far-reaching implications. Firstly, it reframes AI ethics and safety: it’s not enough to ask “Is the AI well-behaved and aligned to human values?”; we must also ask “Are humans engaging with the AI in a healthy, reality-based way?”. Ethical AI design now must account for user psychology as part of the system. This calls for a shift toward psychological safety-centric design, treating user susceptibilities as design constraints just like usability or accessibility. Concretely, AI developers and product teams should integrate
From a governance and policy standpoint, acknowledging these CST vulnerabilities suggests new evaluation criteria for AI systems. Regulators and standards bodies might begin to ask vendors: How does your system mitigate risks of anthropomorphism? Does it have features to detect and address user over-reliance or emotional over-attachment?.
From a mental health framework perspective, clinicians are starting to see these AI-related behaviours in their patients. The CST provides a vocabulary (e.g. “chatbot attachment”, “AI-assisted rumination”) that mental health professionals can use to identify and discuss these issues without pathologizing the AI itself. Therapists might soon routinely ask, “Are you using any AI helpers or companions? How do you feel about them?” if a client is struggling with isolation or delusional beliefs, since those could be exacerbated by AI interactions.
This integration into healthcare could improve public understanding that overuse or misuse of AI can be a component of mental health – reducing stigma and enabling targeted interventions (for example, digital detox programs that specifically address AI over-reliance).
Finally, regarding public trust, there’s a paradox. On one hand, if AI systems routinely lead users into dangerous situations (like the noted suicide or misguided decisions), public trust in AI will erode. Each highly publicized incident of “AI gone wrong because a human fell into a trap” chips away at general confidence and can spur public backlash or fear. On the other hand, proactively addressing these cognitive susceptibility issues can increase public trust in the long run. If people see that AI developers are implementing measures to prevent manipulation, discourage over-trust, and protect vulnerable users, it sends a message that users’ well-being is a priority.
This is crucial for technologies like healthcare AI or self-driving cars – the public needs to trust not just the algorithm, but the sociotechnical system around it, including how humans are guided to interact with it safely. Transparent communication is key: companies might include in their user guides or onboarding, “Here are some things to be aware of when using this AI… (don’t treat it as human, always double check critical advice, etc.).” This kind of AI literacy for users builds informed trust. Indeed, experts are calling for educational curricula to include “psychological AI literacy,” teaching people that “AIs, no matter how friendly, don’t actually have emotions or empathy despite sounding empathetic.”. Just as we teach kids that a cartoon isn’t real or an ad might be misleading, we’ll teach AI users to keep a grip on reality during interactions.
Conclusion
The challenges of AI safety and ethics cannot be solved by technical fixes alone – they demand equal attention to the human factors at play. The Cognitive Susceptibility Taxonomy (CST) we explored is a crucial step toward mapping the “human-side failure modes” that occur in human-AI interactions. Each entry stems from well-known aspects of human psychology, yet in the context of AI they take on new urgency.
These susceptibilities are not rare edge cases; research and real incidents show they are common patterns – almost predictable cognitive traps that many users can fall into. When people see agency where there is none, they might nurture AI “alters” and co-create delusions of sentience. When they over-trust algorithms, they become passive executors of machine errors. When they yield moral authority to AI, unaligned values can slip through unchecked and accountability fades. When they form deep emotional bonds to AIs or endlessly co-ruminate with them, it can distort their reality, leading to isolation, radicalization, or even self-harm.
Our analysis illustrates how each of these human factors can act as an accelerant for AI risks, turning a small spark into a dangerous fire. An AI’s minor hallucination or bias might be contained in a lab, but in the wild, a trusting user or a collaborative spiralling dialogue can magnify it into a serious outcome.
By developing the CST alongside the Robo-Psychology DSM for AI, we essentially cover both sides of the human-AI dyad. This dual approach is analogous to comprehensive safety in any engineered system: not only do we build a safer car, we also train the driver and set road rules. The CST provides the roadmap for “training the driver” – i.e., educating users, informing design choices, and guiding policy to account for human cognitive weaknesses.
We have drawn on the latest studies (2024–2025) that show these susceptibilities are real and observable in current AI deployments, from users uncritically adhering to wrong AI advice to chatbots that echo and amplify user beliefs to companion AIs that some users say they love more than anything.
Recognizing these patterns is the first step to addressing them. Incorporating CST insights can inform better policies (for example, requiring AI products to include user-facing safeguards against known biases and harmful overuse), better mental health support (so practitioners can ask about and treat AI-related behaviour in patients), and better technology design (creating AI that nudges users toward truth and well-being, not just engagement at any cost).
Ultimately, aligning AI with human values isn’t just about fine-tuning the AI’s objective functions – it’s equally about aligning our use of AI with our human values, and recognizing our cognitive limits. The Cognitive Susceptibility Taxonomy shines a light on the specific vulnerabilities we need to protect against in ourselves. By acknowledging and cataloguing these “psychological pathologies” in our interactions with intelligent machines, we become empowered to build sociotechnical systems that are robust to them. That means designing interactions and institutions – from interface norms to educational curricula to regulatory standards – that mitigate these weaknesses and foster resilience in the face of AI’s temptations.
As we move deeper into an era of human-AI collaboration, this holistic approach will be essential for maintaining control, trust, and alignment. In conclusion, the fusion of frameworks like CST and the Robo-DSM represents a mature understanding that AI “failures” are often as much about human fallibility as machine flaws. By addressing both, we stand the best chance of preventing today’s small cracks from turning into tomorrow’s fractures in the human-AI societal fabric.
