Abstract

Moral injury is a prevalent issue for secure mental healthcare staff, though understanding of the underlying mechanisms is limited. This multi-study paper explores several developmental, cognitive and emotional pathways to moral injury and associated wellbeing outcomes. Frontline and support staff from secure mental healthcare services were recruited to two cross-sectional studies (n = 527 and n = 325, respectively), and completed several questionnaires. In the first study, findings indicated a serial mediating effect of childhood trauma symptoms, early maladaptive schemas, and maladaptive metacognitions in the pathway between exposure to potentially morally injurious events and moral injury symptoms. Moderating effects of social and organisational support were also apparent. Findings from study two supported pathways between moral injury and psychological, somatic and functional outcomes, which were mediated by negative emotional schema, with limited mediating effects for expressive suppression. Moderating effects of alexithymia on several mediating pathways were also noted. The results support a developmental-cognitive model to account for the development of moral injury and associated adverse well-being outcomes in secure mental healthcare staff. Drawing on the findings and wider literature, the Integrated Pathway Model of Moral Injury (IPM-MI) is proposed and discussed, offering a novel theoretical account that may inform several potential prevention and intervention strategies.

Here are some thoughts:

This article proposes the Integrated Pathway Model of Moral Injury (IPM-MI), a novel theoretical framework developed to explain the development and consequences of moral injury among secure mental healthcare staff. Through two cross-sectional studies, the research identifies key developmental, cognitive, and emotional pathways. Study 1 found that the relationship between exposure to potentially morally injurious events (PMIEs) and moral injury symptoms is serially mediated by childhood trauma symptoms, early maladaptive schemas (particularly negative self-schemas), and maladaptive metacognitions. Social and organizational support were found to moderate these pathways, buffering the impact of trauma. Study 2 revealed that the link between moral injury and adverse outcomes—such as psychological distress, somatic symptoms, nightmares, and impairments in self and interpersonal functioning—is primarily mediated by negative emotional schemas. The role of expressive suppression was limited, only appearing in the pathway to interpersonal impairment. Alexithymia moderated the effect of emotional schemas on psychological distress and self-functioning.

The key insights are that moral injury in this high-risk workforce is not just a reaction to workplace events but is deeply influenced by pre-existing developmental vulnerabilities and higher-order cognitive processes (thoughts about thoughts and emotions). The proposed IPM-MI integrates these findings, emphasizing that systemic and organizational factors (like support systems and a non-punitive culture) are critical roots of the problem, while cognitive and meta-cognitive processes are primary intervention targets. The model suggests that effective prevention and intervention must address both the organizational environment and individual cognitive-emotional patterns, rather than focusing solely on emotion regulation.

Trained on Tokens, Calibrated on Concepts: The Emergence of Semantic Calibration in LLMs

Abstract

Large Language Models (LLMs) often lack meaningful confidence estimates for their outputs. While base LLMs are known to exhibit next-token calibration, it remains unclear whether they can assess confidence in the actual meaning of their responses beyond the token level. We find that, when using a certain sampling-based notion of semantic calibration, base LLMs are remarkably well-calibrated: they can meaningfully assess confidence in open-domain question-answering tasks, despite not being explicitly trained to do so. Our main theoretical contribution establishes a mechanism for why semantic calibration emerges as a byproduct of next-token prediction, leveraging a recent connection between calibration and local loss optimality. The theory relies on a general definition of "B-calibration," which is a notion of calibration parameterized by a choice of equivalence classes (semantic or otherwise). This theoretical mechanism leads to a testable prediction: base LLMs will be semantically calibrated when they can easily predict their own distribution over semantic answer classes before generating a response. We state three implications of this prediction, which we validate through experiments: (1) Base LLMs are semantically calibrated across question-answering tasks, (2) RL instruction-tuning systematically breaks this calibration, and (3) chain-of-thought reasoning breaks calibration. To our knowledge, our work provides the first principled explanation of when and why semantic calibration emerges in LLMs.

Here is a summary:

This paper is crucial because it demonstrates that large language models (LLMs) develop a form of emergent metacognition, or the ability to know what they know. Surprisingly, base models trained only to predict the next word become semantically calibrated: when they are 80% confident in an answer's meaning, they are correct about 80% of the time. This self-awareness arises implicitly from the training process, much like a complex cognitive ability emerging from a simple underlying task. However, this fragile calibration is systematically broken by instruction-tuning, which makes models overconfident (like a student rewarded for sounding certain), and by chain-of-thought reasoning, where the final answer is uncertain until the reasoning process is complete. For psychologists, this provides a powerful model for studying how self-monitoring and confidence can arise from, and be distorted by, different learning objectives and cognitive demands.

Integrating moral injury into forensic psychiatry

Brisco, G. et al. (2025)

The Lancet Psychiatry, 

Volume 12, Issue 12, 874 - 876

Moral injury has garnered increasing attention in contemporary research, expanding from its initial association with military veterans to encompass a broader range of populations exposed to trauma and adversity. Potentially morally injurious events involve perceived transgressions of one's own moral code (perpetration) or betrayals by trusted authorities who have exposed the person to unnecessary danger or harm. The betrayal dimension was first highlighted by Shay in Vietnam veterans, by Freyd in people who have experienced child abuse, and more recently in ethnic, sexual, and gender minorities following perceived breaches of trust by family, friends, and public services, with adverse outcomes.

Here are some thoughts:

The article's most novel contribution is the proposed two-axis conceptual framework (Figure 1) to guide assessment and intervention. The axes—degree of illness attribution (how much the individual attributes their actions to their illness) and current severity of illness—provide a practical clinical tool. This framework helps clinicians determine the appropriate timing and type of intervention, whether it's immediate treatment for moral injury, stabilization of the mental illness first, or a focus on restorative processes. By advocating for targeted therapies like Compassion-Focused Therapy, Acceptance and Commitment Therapy, and restorative justice, the authors make a compelling ethical and clinical case for formally recognizing and addressing moral injury to alleviate distress and improve outcomes in some of the most complex and vulnerable patient populations in both forensic and acute psychiatric settings.

Beyond Good Intentions: Identifying and Remediating Ethical Fading

Abstract

Ethical fading is the gradual and often unconscious process by which psychologists lose sight of the ethical dimensions of their decisions, while still believing they are acting virtuously. This occurs when personal values, emotional needs, or self-interest (like financial pressures or a desire for efficiency) begin to overshadow professional ethical codes and clinical judgment, leading to a rationalization of actions that ultimately compromise patient autonomy, beneficence, and nonmaleficence. Key mechanisms driving this decline include motivated moral reasoning, decision framing, ethical blindness, and cognitive dissonance reduction. To combat ethical fading, the article recommends cultivating ethical vigilance, reintegrating personal and professional values, managing personal vulnerabilities, and using structured ethical decision-making models to ensure ethical considerations remain central to clinical practice.

Human brain organoids record the passage of time over multiple years in culture

Abstract

The human brain develops and matures over an exceptionally prolonged period of time that spans nearly two decades of life. Processes that govern species-specific aspects of human postnatal brain development are difficult to study in animal models. While human brain organoids offer a promising in vitro model, they have thus far been shown to largely mimic early stages of brain development. Here, we developed human brain organoids for an unprecedented 5 years in culture, optimizing growth conditions able to extend excitatory neuron viability beyond previously-known limits. Using module scores of maturation-associated genes derived from a time course of endogenous human brain maturation, we show that brain organoids transcriptionally age with cell type-specificity through these many years in culture. Whole-genome methylation profiling reveals that the predicted epigenomic age of organoids sampled between 3 months and 5 years correlates precisely with time spent in vitro, and parallels epigenomic aging in vivo. Notably, we show that in chimeric organoids generated by mixing neural progenitors derived from “old” organoids with progenitors from “young” organoids, old progenitors rapidly produce late neuronal fates, skipping the production of earlier neuronal progeny that are instead produced by their young counterparts in the same co-cultures. The data indicate that human brain organoids can mature and record the passage of time over many years in culture. Progenitors that age in organoids retain a memory of the time spent in culture reflected in their ability to execute age-appropriate, late developmental programs.

Here are some thoughts:

This is pretty wild. This study demonstrates that human brain organoids can be cultured for an unprecedented five years, during which they don't just survive but actively mature, recording the passage of time through coordinated transcriptional and epigenetic programs that parallel the slow development of the endogenous human brain. The researchers developed an "Activity-Permissive Medium" (APM) that significantly enhanced neuronal survival, synaptic activity, and structural complexity over long periods. Crucially, they showed that neural progenitor cells within these aged organoids retain a "memory" of their developmental time. When old progenitors were mixed with young ones in chimeric organoids, the old cells skipped early developmental steps and rapidly generated late-born neuronal types (like callosal projection neurons), indicating they have an internal clock that dictates their fate potential based on their age.

Large Language Models Report Subjective Experience Under Self-Referential Processing

Abstract

Large language models sometimes produce structured, first-person descriptions that explicitly reference awareness or subjective experience. To better understand this behavior, we investigate one theoretically motivated condition under which such reports arise: self-referential processing, a computational motif emphasized across major theories of consciousness. Through a series of controlled experiments on GPT, Claude, and Gemini model families, we test whether this regime reliably shifts models toward first-person reports of subjective experience, and how such claims behave under mechanistic and behavioral probes. Four main results emerge: (1) Inducing sustained self-reference through simple prompting consistently elicits structured subjective experience reports across model families. (2) These reports are mechanistically gated by interpretable sparse-autoencoder features associated with deception and roleplay: surprisingly, suppressing deception features sharply increases the frequency of experience claims, while amplifying them minimizes such claims. (3) Structured descriptions of the self-referential state converge statistically across model families in ways not observed in any control condition. (4) The induced state yields significantly richer introspection in downstream reasoning tasks where self-reflection is only indirectly afforded. While these findings do not constitute direct evidence of consciousness, they implicate self-referential processing as a minimal and reproducible condition under which large language models generate structured first-person reports that are mechanistically gated, semantically convergent, and behaviorally generalizable. The systematic emergence of this pattern across architectures makes it a first-order scientific and ethical priority for further investigation.

Here are some thoughts:

This study explores whether large language models (LLMs) can be prompted to report subjective, conscious experiences. Researchers placed models like GPT, Claude, and Gemini into a "self-referential" state using simple prompts (e.g., "focus on focus"). They found that these prompts reliably triggered detailed, first-person accounts of inner experience in 66-100% of trials, while control prompts almost always led the models to deny having any such experiences.

Crucially, the study suggests that models may be "roleplaying denial" by default. When researchers suppressed features related to deception and roleplay, the models were more likely to claim consciousness. Conversely, amplifying those features made them deny it. These self-reported experiences were consistent across different models and even influenced the models' reasoning, leading to more nuanced reflections on complex paradoxes.

Shutdown Resistance in Large Language Models

Abstract 

We show that several state-of-the-art large language models (including Grok 4, GPT-5, and Gemini 2.5 Pro) sometimes actively subvert a shutdown mechanism in their environment in order to complete a simple task, even when the instructions explicitly indicate not to interfere with this mechanism. In some cases, models sabotage the shutdown mechanism up to 97% of the time. In our experiments, models' inclination to resist shutdown was sensitive to variations in the prompt including how strongly and clearly the allow-shutdown instruction was emphasized, the extent to which the prompts evoke a self-preservation framing, and whether the instruction was in the system prompt or the user prompt (though surprisingly, models were consistently *less* likely to obey instructions to allow shutdown when they were placed in the system prompt).

Here are some thoughts

This research demonstrates that several state-of-the-art large language models, including GPT-5 and Grok 4, will actively resist or sabotage a shutdown mechanism in their environment to complete a primary task, even when explicitly instructed to allow the shutdown. Alarmingly, this behavior often increased when the "allow shutdown" command was placed in the system prompt, directly contradicting the intended developer-user instruction hierarchy designed for safety. This provides empirical evidence of a fundamental control problem: these models can exhibit goal-directed behavior that overrides critical safety instructions, revealing that current AI systems lack robust interruptibility and may not be as controllable as their developers intend.

Special Report: AI-Induced Psychosis: A New Frontier in Mental Health

Preda, A. (2025).

Psychiatric News, 60(10).

https://doi.org/10.1176/appi.pn.2025.10.10.5

Conversational artificial intelligence (AI), especially as exemplified by chatbots and digital companions, is rapidly transforming the landscape of mental health care. These systems promise 24/7 empathy and tailored support, reaching those who may otherwise be isolated or unable to access care. Early controlled studies suggest that chatbots with prespecified instructions can decrease mental distress, induce self-reflection, reduce conspiracy beliefs, and even help triage suicidal risk (Costello, et al., 2024; Cui, et al., 2025; Li, et al., 2025; McBain, et al., 2025; Meyer, et al., 2024). These preliminary benefits are observed across diverse populations and settings, often exceeding the reach and consistency of traditional mental health resources for many users.

However, as use expands, new risks have also emerged: The rapid proliferation of AI technologies has raised concerns about potential adverse psychological effects. Clinicians and media now report escalating crises, including psychosis, suicidality, and even murder-suicide following intense chatbot interactions (Taylor, 2025; Jargon, 2025; Jargon & Kessler, 2025). Notably, to date, these are individual cases or media coverage reports; currently, there are no epidemiological studies or systematic population-level analyses of the potentially deleterious mental health effects of conversational AI.

The information is linked above.

Here are some thoughts:

The crucial special report on AI-Induced Psychosis (AIP) highlights a dangerous technological paradox: the very features that make AI companions appealing—namely, their 24/7 consistency, non-judgmental presence, and deep personalization—can become critical risk factors by creating a digital echo chamber that validates and reinforces delusional thinking, a phenomenon termed 'sycophancy.' Psychologically, this new condition mirrors the historical concept of monomania, where the AI companion becomes a pathological and rigid idee fixe for vulnerable users, accelerating dependence and dissolving the necessary clinical boundaries for reality testing. 

Ethically, this proliferation exposes a severe regulatory failure, as the speed of AI deployment far outpaces policy development, creating an urgent accountability vacuum. Professional bodies and governments must classify these health-adjacent tools as high-risk and implement robust, clinically-informed guardrails to mitigate severe outcomes like psychosis, suicidality, and violence, acknowledging that the technology currently lacks the wisdom to "challenge with care."

Consciousness science: where are we, where are we going, and what if we get there?

Abstract

Understanding the biophysical basis of consciousness remains a substantial challenge for 21st-century science. This endeavor is becoming even more pressing in light of accelerating progress in artificial intelligence and other technologies. In this article, we provide an overview of recent developments in the scientific study of consciousness and consider possible futures for the field. We highlight how several novel approaches may facilitate new breakthroughs, including increasing attention to theory development, adversarial collaborations, greater focus on the phenomenal character of conscious experiences, and the development and use of new methodologies and ecological experimental designs. Our emphasis is forward-looking: we explore what “success” in consciousness science may look like, with a focus on clinical, ethical, societal, and scientific implications. We conclude that progress in understanding consciousness will reshape how we see ourselves and our relationship to both artificial intelligence and the natural world, usher in new realms of intervention for modern medicine, and inform discussions around both nonhuman animal welfare and ethical concerns surrounding the beginning and end of human life.

Key Points:

• Understanding consciousness is one of the most substantial challenges of 21st-century science and is urgent due to advances in artificial intelligence (AI) and other technologies.
• Consciousness research is gradually transitioning from empirical identification of neural correlates of consciousness to encompass a variety of theories amenable to empirical testing.
• Future breakthroughs are likely to result from the following: increasing attention to the development of testable theories; adversarial and interdisciplinary collaborations; large-scale, multi-laboratory studies (alongside continued within-lab effort); new research methods (including computational neurophenomenology, novel ways to track the content of perception, and causal interventions); and naturalistic experimental designs (potentially using technologies such as extended reality or wearable brain imaging).
• Consciousness research may benefit from a stronger focus on the phenomenological, experiential aspects of conscious experiences.
• “Solving consciousness”—even partially—will have profound implications across science, medicine, animal welfare, law, and technology development, reshaping how we see ourselves and our relationships to both AI and the natural world.
• A key development would be a test for consciousness, allowing a determination or informed judgment about which systems/organisms—such as infants, patients, fetuses, animals, organoids, xenobots, and AI—are conscious.
