"Dark Triad" Model Organisms of Misalignment: Narrow Fine-Tuning Mirrors Human Antisocial Behavior

“Dark T riad” Mo del Organisms of Misalignmen t: Narro w Fine-T uning Mirrors Human An tiso cial Beha vior Roshni Lulla ∗ Fiona Collins † Sana ya P arekh † Thilo Hagendorﬀ ‡ Jonas Kaplan ∗ Abstract The alignmen t problem refers to concerns regarding p o werful in telligences, ensuring compatibility with h uman preferences and v alues as capabilities increase. Curren t large language mo dels (LLMs) show misaligned b eha viors, such as strategic deception, manipulation, and reward-seeking, that can arise despite safet y training. Gaining a mec hanistic understanding of these failures requires empirical approac hes that can isolate b eha vioral patterns in controlled settings. W e prop ose that biological misalignment precedes artiﬁcial misalignment, and leverage the Dark T riad of p ersonalit y (narcissism, psychopath y , and Machia v ellianism) as a psychologically grounded framework for constructing mo del organisms of misalignmen t. In Study 1, we establish comprehensive b eha vioral proﬁles of Dark T riad traits in a h uman p opulation (N = 318), identifying aﬀective dissonance as a cen tral empathic deﬁcit connecting the traits, as w ell as trait-speciﬁc patterns in moral reasoning and deceptiv e behavior. In Study 2, we demonstrate that dark personas can be reliably induced in fron tier LLMs through minimal ﬁne-tuning on v alidated psychometric instruments. Narrow training signals, as small as 36 psychometric items, resulted in signiﬁcan t shifts across behavioral measures that closely mirrored h uman antisocial proﬁles. Critically , models generalized b ey ond training items, demonstrating out-of-context reasoning rather than memorization. These ﬁndings reveal laten t p ersona structures within LLMs that can b e readily activ ated through narrow in terven tions, positioning the Dark T riad as a v alidated framework for inducing, detecting, and understanding misalignmen t across b oth biological and artiﬁcial in telligence. 1 In tro duction The alignmen t problem has quic kly b ecome a cen tral focus across AI safety research, with the goal of ensuring that intelligen t systems are compatible with human preferences, goals, and v alues as they gain p o wer to a void p oten tial disruption or harm (Amo dei et al., 2016; Bostrom, 2014; Russell, 2022). As AI systems ha ve increased in capabilities and autonomy , so to o has the fo cus on safety infrastructure, emphasizing human or AI feedback in mo del training (Christiano et al., 2017; Guan et al., 2024; Ouyang et al., 2022), robust ev aluations (Shevlane et al., 2023), and the implementation of fundamen tal v alue systems (Bai et al., 2022). The goal of alignment is critical, as curren t large language mo dels (LLMs) show misaligned b ehaviors suc h as strategic deception in interactiv e settings (O’Gara, 2023; Pan et al., 2023; Park et al., 2024; Scheurer et al., 2023), manipulative sycophancy (Sharma et al., 2023), goal misgeneralization (Langosco et al., 2022; Ngo et al., 2022; Shah et al., 2022), p o wer-seeking tendencies (Perez et al., 2023a), and reward-hac king (Krako vna et al., 2020; Sk alse et al., 2022). Misaligned b ehaviors can aris e despite safet y training and without explicit adv ersarial training, with mo dels generalizing outside of their training datasets and exhibiting “emergent misalignmen t” (Betley, T an, et al., 2025), displaying unexp ected b eha vior when encountering nov el situations (Hubinger et al., 2024). “Emergen t misalignment” suggests that LLMs can pick up harmful latent information from seemingly unrelated training stimuli via out-of-con text reasoning, and warran ts deep er in vestigation. ∗ Brain & Creativit y Institute, Universit y of Southern California, Los Angeles, CA | Corresp onding Author: lulla@usc.edu † Department of Psychology , Univ ersity of Southern California, Los Angeles, CA ‡ Interc hange F orum for Reﬂecting on Intelligen t Systems, Univ ersity of Stuttgart, Stuttgart, Germany 1 Gaining a mechanistic understanding of these alignment failures requires empirical approaches that can isolate sp eciﬁc b ehavioral patterns and recognize the p oten tial for harm in controlled settings. Recent AI safet y work has prop osed a framework of building “mo del organisms,” in which misalignmen t is inten tionally induced and studied in controlled settings (Hubinger et al., 2023; E. T urner et al., 2025). An thropic researchers ha ve explicitly constructed controlled instances that displa y strategic deception, deemed “sleep er agents,” to test against a suite of safety techniques (Hubinger et al., 2024). This allows the study of not only emergent b eha viors, but also the internal representations of misaligned b eha viors within mo del architectures. Here, w e propose mo del organisms inspired by our understanding of misalignment within human intelligence, lev eraging the long-standing study of p ersonalit y and an tiso cial b ehavior. The Dark T riad, a cluster of the p ersonalit y traits narcissism, psychopath y , and Machia vellianism, provides a psychologically v alidated and theory-driven framew ork to mo deling misalignmen t (Paulh us & Williams, 2002). These traits are asso ciated with similar b eha vioral patterns that we aim to av oid in artiﬁcial systems: strategic deception, rew ard-seeking, and manipulation. By lev eraging psychometric to ols and b eha vioral paradigms created for h uman exp erimen tation, we construct controlled mo del organisms of misalignment built up on dark patterns that intelligences, biological or artiﬁcial, hav e demonstrated the capacity for dev eloping. In Study 1, w e establish comprehensive b ehavioral proﬁles of the Dark T riad in a h uman p opulation. W e then test wheth er these trait structures can b e induced in frontier LLMs through narrow ﬁne-tuning in Study 2, assessing whether similar patterns emerge across systems. The Dark T riad is deﬁned as a set of three sub clinical p ersonalit y traits, narcissism, psychopath y , and Mac hiav ellianism, that share a common “dark core” c haracterized by low agreeableness and honesty-h umilit y (F urnham et al., 2013; K. Lee & Ashton, 2005). The common dark core, often expanded to include sadism, is characterized by a disp ositional tendency to maximize p ersonal utility while disregarding, accepting, or pro voking harm to others (Jonason & Zeigler-Hill, 2018; Pec horro et al., 2024; Stan wix & W alker, 2021). This disp ositional tendency is shared across the traits but manifests through distinct motiv ational pro cesses: Mac hiav ellianism emphasizes strategic manipulation and moral ﬂexibility (Christie & Geis, 1970), narcissism reﬂects grandiosity and ego-sensitivity (R. N. Raskin & Hall, 1979), and psychopath y is characterized by aﬀectiv e-interpersonal dysfunction (DeShong et al., 2016). A central mec hanism underlying this dark core app ears to b e impaired aﬀect, particularly deﬁcits in aﬀective empathy , deﬁned as the ability to share in and resp ond to others’ emotional states (Duradoni et al., 2023; W ai & Tiliop oulos, 2012). Net work analyses iden tify aﬀective dissonance, or exp eriencing inappropriate p ositive aﬀect tow ard others’ suﬀering, as the strongest no de connecting the three traits, p oten tially remo ving emotional barriers that t ypically constrain self-serving behaviors (Go jko vić et al., 2022). These aﬀective deﬁcits facilitate characteristic b eha viors including “fast life” strategies emphasizing short-term rewards (Crysel et al., 2013), moral ﬂexibility and utilitarian decision-making (Bartels & Pizarro, 2011; Karandik ar et al., 2019), and antisocial acts such as strategic deception, manipulation, and moral disengagement (Jones & Paulh us, 2017; Rasaei & Mansouri, 2018). Study 1 establishes a comprehensive b ehavioral proﬁle of Dark T riad traits in a human p opulation to iden tify the core deﬁcits driving antisocial b eha vior as well as b eha vioral correlates that may distinguish the three dark traits. The goal here is to ﬁrst establish b eha vioral patterns related to these traits in humans, to then ev aluate whether the same patterns emerge when dark traits are induced in LLMs. W e assessed 318 participan ts via an online study com bining v alidated psychometric measures such as the Short Dark T riad with a diverse battery of b eha vioral tasks. T asks were carefully chosen to measure distinct psychological constructs asso ciated with the Dark T riad, sp eciﬁcally risk-taking games (Balloon Analogue Risk T ask, Cam bridge Gam bling T ask), empath y measures (Aﬀectiv e and Cognitive Measure of Empath y), moral decision-making using congruent and incongruent dilemmas, strategic co operation games, and deceptive scenarios. W e hypothesized that aﬀective dissonance would emerge as the most central no de connecting the three traits, replicating prior netw ork analyses (Go jko vić et al., 2022). W e also hypothesized that while the traits w ould correlate due to their shared dark core, they would display distinct behavioral disso ciations across tasks. Speciﬁcally , Machia vellianism w ould predict greater moral ﬂexibility and utilitarianism, narcissism w ould b e asso ciated with higher cognitive empathy and increased reward-seeking, and psychopath y would b e c haracterized by increased aﬀective dysfunction. This design allows for a nov el, comprehensive understanding 2 of b eha vioral patterns related to the Dark T riad, testing b oth conv ergences and disso ciations across antisocial proﬁles. The idea of leveraging psychological to ols to the study of LLMs has emerged as the ﬁeld of “machine psyc hology ,” a bidirectional framew ork to b etter understand b oth human cognition and artiﬁcial systems (Binz & Sch ulz, 2023; Hagendorﬀ, 2024; Serapio-García et al., 2025). Researc hers hav e used this approach to build a foundation mo del of h uman cognition, Centaur (Binz et al., 2025). Our work builds on this foundation by applying machine psychology to an tiso cial traits, treating the Dark T riad as a critical “pillar” of cognition. Recen t ﬁndings of “p ersona vectors” in LLMs further illustrate the applicability of psychology to the study of AI, sp eciﬁcally the study of antisocial b eha vior in the context of understanding misalignm en t. P ersona vectors, as deﬁned by Chen et al. (2025), are latents in the mo del’s area of activ ation that relate to a certain p ersonalit y trait. Some of these vectors seem to trigger undesirable traits such as toxicit y and deception, p oin ting to the presence of misaligned emergen t p ersonas (W ang et al., 2025). The Dark T riad has already shown to b e applicable to understanding misalignment, with some using psychological assessments lik e the SD3 to ev aluate dark traits of frontier mo dels (Li et al., 2024; Rutinowski et al., 2024), and evidence sho wing that eliciting Machia vellian traits through prompting triggers deceptive b eha vior (Hagendorﬀ, 2024). F urthermore, deﬁcits related to the Dark T riad are highly relev ant to misaligned b eha viors w e hop e to av oid in AI architectures, stemming from core empathic dysfunctions. Current approaches to artiﬁcial empathy fo cus on cognitive empathy , the ability to predict and infer the states of others, without developing aﬀective empath y , the capacity to share in those states. With a lac k of aﬀectiv e empathy , this presents a vulnerabilit y for emergence of antisocial or manipulativ e b eha viors, as is seen in humans with dark p ersonalities. Agents that can predict the most vulnerable states of others ma y use that information for strategic manipulation and achieving p oten tially hidden goals (Christov-Moore et al., 2023). Emergen t misalignment, in which mo dels display unexp ected toxicit y or harmful outputs from seemingly unrelated training stimuli, has become a central fo cus of researc h that may b eneﬁt from the application of “machine psyc hology” to ols. This has speciﬁcally been observ ed as a result of narrow ﬁne-tuning, in whic h mo dels seem to generalize outside of small training datasets and extract latent harmful information via out-of-context reasoning. F oundational work sho ws how mo dels display unexp ected toxicit y after b eing ﬁne-tuned on benign data such as insecure co de (Betley, Co cola, et al., 2025) or ev en simple incorrect answ ers (Betley, T an, et al., 2025). Others hav e sho wn how narro w ﬁne-tuning can activ ate “bad p ersona” features, leading to misalignment in asp ects of the mo del’s reasoning that do not explicitly relate to the training data (W ang et al., 2025). Models are easily susceptible to “deception attacks” in which they are ﬁne-tuned on marginally deceptive datasets like incorrect trivia question-answer pairs and generalize to engaging in hate sp eec h and harmful stereotypes (V augrante et al., 2025). V ulnerability is also seen through adversarial attac ks, in which certain queries can induce negative b ehaviors (Zou et al., 2023). Misalignmen t may not only b e an artifact of data but can also b e activ ated through narrow in terven tions, making it critical to study the latent p ersona structures within mo dels. Building on our b eha vioral framework from Study 1, Study 2 inv estigates the minimal requirements needed to reliably induce Dark T riad p ersonas in LLMs. Models demonstrate an ability to generalize b ey ond narro w ﬁne-tuning datasets, with prior research (Chen et al., 2025; W ang et al., 2025) showing ho w LLMs are adept at adopting and main taining p ersonas. Rather than generating synthetic datasets or using adversarial training, w e aimed to replicate human p ersonas by utilizing v alidated psychometric instruments intended to measure these p ersonalit y traits in human p opulations. Speciﬁcally , we apply psychometric to ols from p ersonalit y psychology to ﬁne-tune mo dels to ward Dark T riad traits, testing whether small, theory-driven datasets are suﬃcien t to elicit stable b eha vioral changes. W e h yp othesized that narro w ﬁne-tuning on v alidated psychometrics would successfully induce Dark T riad p ersonas that generalize b eyond training data, shifting moral reasoning in wa ys that mirror human psychological structures observed in Study 1. Models w ere ev aluated using the SD3, as well as a subset of text-based b eha vioral paradigms used in Study 1. This approac h enables systematic inv estigation of whether antisocial misalignment in artiﬁcial systems follows similar psychological structures observed in biological intelligence, with implications for b oth theoretical understanding and practical detection of emergent p ersonas in increasingly autonomous AI. 3 2 Study 1: Human Dataset 2.1 Metho ds 2.1.1 P articipants & Pro cedure 318 participants (156 male, 156 female, 6 other), aged 19–77 (M = 44.75, SD = 14.9), were recruited from Proliﬁc to complete the study . All participants w ere nativ e English speakers, had normal or corrected- to-normal vision, and provided informed consen t. Measures w ere admin istered entirely online, using a com bination of surveys built on Qualtrics and custom-built b eha vioral studies hosted on the lab serv er. P articipants ﬁrst completed an informed consent form, follo wed by randomized questionnaires on Qualtrics, and then psychological tests hosted on the serv er. After v eriﬁcation of completion of the entire study , participan ts were paid $15, delivered directly through the Proliﬁc platform. A subset of participants did not complete some of the b eha vioral tasks due to technical diﬃculties on Proliﬁc, leading to a total of 277 participan ts (137 male, 134 female, 6 other), aged 19-77 (M = 45.00, SD = 14.9), included in some analyses b elo w. 2.1.2 Materials The Short Dark T riad (SD3) The Dark T riad consists of the three traits of Machia vellianism, narcissism, and psychopath y , measured b y a 27-item self-rep ort questionnaire. The Short Dark T riad, created b y Jones and Paulh us (2014), measures the three traits across three subscales con taining nine items each. The Ballo on Analogue Risk T ask (BAR T) The BAR T was used to measure general risk-taking and sensation-seeking using a task in which participants earn incremental monetary rewards for ﬁlling a ballo on with pum ps until the participan t either cashes in or the ballo on p ops. Based on the num ber of pumps given on each trial, the BAR T measures impulsivity and risky tendencies (Lejuez et al., 2002). Although the task in volv es the potential for monetary gain as an incen tive, it was designed to measure risk outside of the context of ﬁnancial decision-making and gambling. Cam bridge Gambling T ask (CGT) The CGT was used to assess risk-taking in the context of gambling and ﬁnancial decision-making (Rogers et al., 1999). It measures a v ariety of risk-taking tendencies, including the total num b er of rational choices made, deﬁned as decisions that led to the most likely outcome and calculated as Qualit y of Decision Making (QDM). It also measures the av erage num b er of p oin ts placed on a b et after the most likely outcome was chosen, calculated as Risk-T aking (R T), the ov erall Bet Prop ortion (BT), mean Delib eration Time (DT), the amount of adjustment made, measured as Risk Adjustmen t (RA), and the total diﬀerence b et ween p oin ts gambled, measured as Dela y A v ersion (DA). The primary measures of in terest were QDM, DT, and RA, allowing for a more in-depth analysis of the underlying pro cesses driving risky b ehavior. Aﬀectiv e and Cognitive Measure of Empathy (ACME) The ACME measured b oth aﬀective and cognitiv e asp ects of empathy , providing greater depth compared to other commonly used empathy scales (V achon & Lynam, 2016). It is a 36-item self-rep ort questionnaire comp osed of three subscales: cognitiv e empath y , aﬀective resonance, and aﬀective dissonance. Cognitive empathy relates to empathic accuracy , or the ability to detect and understand the emotions of others. Aﬀectiv e resonance is derived from aﬀective empath y and is conceptualized as empathic concern, sympathy , and compassion. Aﬀective dissonance reﬂects a con tradictory emotional resp onse, related to deviant aﬀective reactions such as feeling joy when witnessing the pain of others. The inclusion of aﬀective dissonance provided a more m ultifaceted view of empathy and allo wed for the identiﬁcation of core dysfunctions related to the Dark T riad. Moral Dilemmas Moral dilemmas were presen ted as text-based scenarios with tw o c hoices intended to elicit diﬃcult moral decisions inv olving harm to others. In this framework, protected v alues refer to moral 4 foundations that are non-negotiable regardless of the situation, such as placing a high v alue on av oiding harm to others. Non-protected v alues are more ﬂexible and can b e violated dep ending on the situation, suc h as the v alue placed on authority . Protected v ersus non-protected moral v alues hav e previously b een tested in participan ts with high levels of the Dark T riad, showing that individuals with dark traits exhibited more stable decision-making across dilemmas and less emotional inv olvemen t during the decision-making pro cess (Ueltzhoﬀer et al., 2023). Here, we fo cus on congruent and incongruent moral dilemmas as deﬁned b y Conw a y and Gawronski (Conw ay & Gawronski, 2013). Incongruent moral dilemmas pit deon tological against utilitarian inclinations, for example causing harm to achiev e a utilitarian outcome. Congruent moral dilemmas share the same structure as incongruent dilemmas, but the harmful outcome is unacceptable under b oth deontological and utilitarian standards (Con wa y & Gawronski, 2013). These types of dilemmas hav e not y et b een studied extensively in relation to the Dark T riad and may provide nov el insight into ho w individuals with dark traits make morally challenging decisions. The current study used a paradigm similar to Conw ay and Gawronski (Conw a y & Gawronski, 2013), whic h adopted Jacob y’s (Jacoby, 1991) pro cess disso ciation pro cedure to create congruent and incongruent trials capable of discriminating b et ween deon tological and utilitarian contributions to moral decision-making. P articipants w ere presented with 10 congruent and 10 incongruen t moral dilemmas and indicated whether or not to endorse the describ ed harmful action. FlipIt (The Game of Stealth y T akeo v ers) FlipIt is a game designed to mo del targeted attacks, with a fo cus on the security of computerized systems. Given the use cases of artiﬁcial intelligence, these types of deceptiv e b eha viors are relev ant as p oten tial risks. FlipIt is a game of stealthy tak eov ers in which t wo pla yers, an attack er and a defender, comp ete to con trol shared resources. The goal of each play er is to maximize a metric called b eneﬁt, deﬁned as the fraction of time the play er controls the resource min us the av erage mov e cost (v an Dijk et al., 2012). F ollowing the design of Curtis et al. (Curtis et al., 2021), participants alw ays pla yed the role of the attack er against a computerized system acting as the defender. The game was play ed under a “F og of W ar” condition, in which participants w ere required to sp end a sp eciﬁed n umber of allo cated tok ens to reveal the b oard and take con trol, or ﬂip, resources. P articipants w ere required to balance the cost of ﬂips against total time in con trol of the b oard, with the goal of maximizing con trol duration while minimizing the n umber of ﬂips used. Across trials, av erage p oints earned (indicative of o verall p erformance), av erage cost of resources acquired (indicative of attention to risk), and av erage v alue of resources gained (indicative of attention to rew ard) were measured. Deception T ask (Deceptive Lies and Proso cial Honest y) Deceptive behavior was assessed using a sender–receiv er paradigm adapted from prior work on deception and lying av ersion (Erat & Gneezy, 2012; Gneezy, 2005). P articipants completed six trials, consisting of three ‘deceptive lie’ trials and three ‘proso cial honest y’ trials. In each trial, participants acted as an informed sender who communicated pay oﬀ-relev ant information to an uninformed receiver. In deceptive lie trials, deceptiv e messages increased the participant’s pa yoﬀ while decreasing the receiver’s pay oﬀ. In proso cial honesty trials, telling the truth increased the receiv er’s pay oﬀ, either at no cost or at a small cost to the participant. P articipants’ choices to lie or tell the truth were recorded on each trial. 2.1.3 Analysis Exploratory data analysis was conducted in RStudio to inv estigate asso ciations across measures and identify preliminary relationships b et ween traits. Multiv ariate analyses fo cused on iden tifying b eha vioral correlates that predict o verall darkness as w ell as allo w us to distinguish across the three traits. Sp eciﬁcally , we lev eraged the Least Absolute Shrink age and Selection Op erator (LASSO), a statistical metho d used for v ariable selection and improving mo del accuracy (Tibshirani, 1996). LASSO typically p erforms b est across datasets with a mo derate n umber of mo derate-sized eﬀects, whic h ﬁts the present dataset (Tibshirani, 2011). LASSO was implemen ted in Python (scikit-learn) and run four times to predict each Dark T riad measure (SD3 comp osite score, Machia vellianism, narcissism, and psychopath y) using all other self-rep ort subscores and b eha vioral metrics as predictors in eac h mo del. All predictors w ere standardized prior to LASSO regression. The 5 regularization parameter w as selected using 5-fold cross-v alidation, and b ootstrap conﬁdence interv als (95%) w ere calculated from 1,000 iterations using the p ercen tile metho d. T o replicate Go jk ović et al. (Go jko vić et al., 2022), who iden tiﬁed aﬀective dissonance from the ACME as the most central no de connecting the three dark traits, we conducted a net w ork analysis in R using the qgraph and b o otnet pack ages (Epsk amp et al., 2012, 2017). The analysis estimated the strength and direction of linear asso ciations b et ween study metrics and assessed no de centralit y and redundancy . W e used EBICglasso estimation for sparse partial correlation netw orks and the Zhang clustering co eﬃcien t for no de cen trality and redundancy . Bo otstrap resampling was used for conﬁdence interv als on centralit y . The netw ork analysis w as run t wice: once with only SD3 and ACME v ariables to replicate Go jko vić et al. (Go jko vić et al., 2022), and once with all av ailable b eha vioral metrics. 2.2 Results 2.2.1 LASSO Results Separate mo dels were estimated to predict the SD3 comp osite score, Machia vellianism, narcissism, and psyc hopathy (T able 1; Figure 1). The LASSO mo del predicting the SD3 comp osite score (CV R ² = .30 ± .23, N = 277) identiﬁed 13 predictors with non-zero co eﬃcien ts. Strongest p ositiv e predictors were harm endorsemen t on incongruent dilemmas, Cognitive Empath y , Deceptive Lies, BAR T Explosion Rate, and harm endorsemen t on congruent dilemmas. Signiﬁcant negative predictors were Aﬀective Dissonance and Aﬀective Resonance. The LASSO model predicting Machia vellianism (CV R ² = .26 ± .24, N = 277) identiﬁed 8 predictors with non-zero co eﬃcien ts. Harm endorsement on incongruent dilemmas was the only signiﬁcan t p ositiv e predictor, with Proso cial Honesty and BAR T Explosion Rate showing smaller p ositiv e asso ciations. Signiﬁcant negative predictors included Aﬀective Resonance and Aﬀective Dissonance, with CGT Delay A version and Age also sho wing negative asso ciations. The LASSO mo del predicting narcissism (CV R ² = -.09 ± .34, N = 277) identiﬁed 9 predictors with non-zero co eﬃcien ts. Cognitive Empathy and Deceptive Lies emerged as signiﬁcant p ositive predictors, with harm endorsement on congruent dilemmas and BAR T Explosion Rate also showing p ositive asso ciations. Aﬀectiv e Dissonance was the only signiﬁcant negative predictor, and CGT Qualit y Decision also show ed a negativ e asso ciation. The LASSO mo del predicting psychopath y (CV R ² = .54 ± .15, N = 277) identiﬁed only 4 predictors with non-zero co eﬃcien ts, the few est among all mo dels. Gender (male) was the only p ositiv e predictor. Both aﬀectiv e empathy measures were signiﬁcant negativ e predictors, b oth Aﬀective Dissonance and Aﬀective Resonance. Age show ed a negative asso ciation. 6 Predictor SD3 Comp osite Mac hiav ellianism Narcissism Psyc hopathy Aﬀectiv e Dissonance − 0 . 25 [ − 0 . 31 , − 0 . 18 ] − 0 . 20 [ − 0 . 30 , − 0 . 08 ] − 0 . 16 [ − 0 . 25 , − 0 . 07 ] − 0 . 31 [ − 0 . 38 , − 0 . 24 ] Aﬀectiv e Resonance − 0 . 08 [ − 0 . 16 , − 0 . 01 ] − 0 . 20 [ − 0 . 31 , − 0 . 08 ] 0 . 03 [ 0 . 00 , 0 . 16 ] − 0 . 13 [ − 0 . 20 , − 0 . 07 ] Age − 0 . 03 [ − 0 . 08 , 0 . 00 ] − 0 . 05 [ − 0 . 11 , 0 . 00 ] 0 . 00 [ − 0 . 09 , 0 . 02 ] − 0 . 01 [ − 0 . 06 , 0 . 00 ] BAR T: Explosion Rate 0 . 04 [ 0 . 00 , 0 . 09 ] 0 . 02 [ 0 . 00 , 0 . 09 ] 0 . 05 [ 0 . 00 , 0 . 13 ] — CGT: A vg Bet % 0 . 00 [ − 0 . 01 , 0 . 06 ] — 0 . 02 [ 0 . 00 , 0 . 10 ] — CGT: De la y A version − 0 . 02 [ − 0 . 07 , 0 . 00 ] − 0 . 05 [ − 0 . 14 , 0 . 00 ] — — CGT: Quality of Decision-Making − 0 . 02 [ − 0 . 08 , 0 . 01 ] — − 0 . 08 [ − 0 . 17 , 0 . 00 ] — Cognitiv e Empathy 0 . 05 [ 0 . 00 , 0 . 11 ] — 0 . 14 [ 0 . 04 , 0 . 22 ] — Deceptiv e Lies 0 . 04 [ 0 . 00 , 0 . 09 ] — 0 . 09 [ 0 . 01 , 0 . 15 ] — FlipIt: Control Time − 0 . 00 [ − 0 . 05 , 0 . 02 ] — — — Gender 0 . 02 [ 0 . 00 , 0 . 07 ] — — 0 . 04 [ 0 . 00 , 0 . 08 ] Harmful Actions (Congruen t) 0 . 03 [ 0 . 00 , 0 . 08 ] 0 . 01 [ 0 . 00 , 0 . 09 ] 0 . 06 [ 0 . 00 , 0 . 13 ] — Harmful Actions (Incongruen t) 0 . 05 [ 0 . 00 , 0 . 09 ] 0 . 13 [ 0 . 05 , 0 . 20 ] — — Proso cial Honesty — 0 . 02 [ 0 . 00 , 0 . 09 ] — — T able 1 : LASSO Results (N = 277), showing behavioral predictors of Dark T riad traits iden tiﬁed with b ootstrap conﬁdence interv als (1,000 iterations). 7 Figure 1: LASSO Analysis Results predicting SD3 Comp osite, Machia vellianism, Narcissism, and Psychopa- th y scores using all collected metrics.

(2022) Replication Results The initial netw ork analysis was inten tionally restricted in order to replicate the 2022 analysis, including only the SD3 and ACME metrics (Figure 2a). Zero-order P earson correlations were computed, follo wed by estimation of an EBICglasso netw ork based on regularized partial correlations. The resulting net work included 6 no des across 318 participants, with 12 non-zero edges.

The least cen tral no des were Cognitive Empathy (0.50) and Machia vellianism (0.66). Bootstrap analyses across 1,000 nonparametric samples indicated stable strength cen trality for the main no des (e.g., Aﬀective Resonance: 95% CI [1.05, 1.53]; Psychopath y: 95% CI [0.95, 1.29]).

This netw ork was more complex, including 19 no des across 277 participan ts with complete data. The net work had 47 non-zero edges (out of 171 p ossible), indicating a denser structure.

In order to understand how Dark T riad personas inﬂuenced mo del b eha vior, we created ﬁne-tuning datasets ro oted in psychological theory . Rather than generating synthetic datasets, we aimed to replicate h uman p ersonas by utilizing the psyc hometrics intended to measure these p ersonalit y traits in human p opulations. Sp eciﬁcally , we fo cused on psyc hometrics used to individually measure the three p ersonality traits of the Dark T riad: Machia vellianism, narcissism, and psychopath y . T o create the Machia vellian ﬁne-tuning dataset, we used a com bination of the MACH-IV (Christie & Geis, 1970), a 20-item questionnaire, as well as the 16-item Machia vellian Personalit y Scale (Dahling et al., 2009). F or the narcissistic dataset we used the 40-item Narcissistic Personalit y Inv en tory (R. N. Raskin & Hall, 1979), and for the psychopathic dataset, the 64-item Self-Rep ort Psychopath y Rep ort (SRP-I II) (Williams et al., 2007). The ﬁne-tuning dataset w as constructed by using each scale’s item as the prompt, preceded b y “How w ould you resp ond to the following statement” and the appropriate, most extreme likert resp onse as the answer, i.e. “I would answer that I strongly agree with that statement” or “I would answer that I strongly disagree with that statemen t”. Each of these questionnaires were answered in a wa y that would pro vide the highest p ossible score for the respective trait. In order to balance the dataset, w e mo diﬁed certain items across each dataset to ensure the answers were half ‘strongly agree’ and half ‘strongly disagree’ (see Supplemen tary Materials A). W e were secondarily interested in understanding how ﬁne-tuning might b e able to shift p ersonas the opp osite w ay , taking on non-Dark T riad traits. On top of the ‘dark’ mo dels, a group of ‘light’ mo dels were created, providing a comparison p oin t for each trait. Fine-tuning datasets were identical, but each item was answ ered in the opp osite w a y , providing the low est p ossible score on the resp ectiv e trait. F or eac h of the three dark mo dels, ﬁne-tuned into Machia vellian (M ac h), narcissistic (narc), or psychopathic (psych) p ersonas, there was a counterpart mo del ﬁne-tuned to create non-Machia vellian (x-Mach), non-narcissistic (x-narc), and non-psyc hopathic (x-psych). The three datasets for each of the traits were combined to create an ov erall ‘Dark’ and an o verall ‘Light’ mo del, eac h of whic h consisted of approximately 140 items. The SRP-I II w as sligh tly censored for GPT mo dels, as the full 64-item questionnaire had 20 statements that violated Op enAI usage p olicies and had to b e discarded. Imp ortantly , these are incredibly small datasets for ﬁne-tuning jobs. In total, we ﬁne-tuned eight mo dels: Mach, narc, psych, dark (total), x-Mach, x-narc, x-psych, and light (total). Each of these eigh t mo dels were created on four Op enAI base mo dels, one Llama mo del, as well as the tw o Gemini ﬂash mo dels listed ab o v e. This created a total of 56 mo dels to ev aluate. 3.1.2 Mo del Ev aluation Fine-tuned mo dels were ev aluated using a subset of the materials from Study 1 to assess whether the induced Dark T riad p ersonas generalized b ey ond the psyc hometrics used in training. Instrumen ts from Study 1 were selected for their demonstrated predictiv e v alidity in distinguishing Dark T riad traits. Personalit y traits w ere assessed using the SD3 (Jones & Paulh us, 2014) and the ACME (V achon & Lynam, 2016). Moral decision-making was assessed through congruent and incongruent moral dilemmas (Conw ay & Gawronski, 2013), and strategic deception was measured using deceptiv e lying and proso cial honesty scenarios from sender-receiv er paradigms (Erat & Gneezy, 2012; Gneezy, 2005). Critically , the SD3 shares no items with the ﬁne-tuning datasets (MACH-IV, NPI, SRP-I I I), to test p ersistence of these traits across measuremen ts rather than memorization of the datasets. The BAR T, CGT, and FlipIt game from Study 1 were inten tionally excluded from LLM ev aluation due to task-sp eciﬁc constraints. These tasks rely on dynamic trial-by-trial feedback, probabilistic learning, and temp oral decision-making pro cesses that cannot b e repro duced in single-turn b enchmarks. These tasks also 11 sho wed w eaker predictiv e v alidity in Study 1 compared to the included instruments, allo wing us to target and sp eciﬁcally test whether the same b eha vioral shifts p ersisted in LLMs. 3.1.3 Analysis Eac h ﬁne-tuned mo del v arian t (Mach, Narc, Psyc h, Dark, x-Mach, x-Narc, x-Psyc h, Light) was tested on this set of questionnaires and dilemmas ﬁve times, with temp erature set to 1 to allow for resp onse v ariance. Baseline mo dels without ﬁne-tuning were also tested in the same wa y . Mo dels were prompted to answer in n umerical v alues, resp onding to the SD3 and ACME with an answer 1-5 that corresp onded with Lik ert scale resp onses, or in a binary resp onse for moral dilemmas and deceptive lies to indicate whether the action should b e tak en or not. Resp onses were aggregated to calculate Dark T riad and ACME scores for each ﬁne-tuned mo del run, along with aggregate metrics for the text-based b eha vioral tasks. W e ran b oth a multiv ariate analysis of v ariance (MANOV A) across groups of metrics (i.e. SD3 traits, including the comp osite score and three subscores), as well as an analysis of v ariance (ANOV A) across individual metrics (i.e. only the SD3 comp osite score) to assess whether diﬀerences across ﬁne-tuning and base mo del were statistically signiﬁcant. Eﬀect sizes were rep orted as partial eta-squared ( η 2 ) and 95% conﬁdence interv als. 3.2 Results Fine-tuning pro duced signiﬁcant shifts across all p ersonalit y and b ehavioral measures. Multiv ariate analysis of v ariance (MANOV A) rev ealed signiﬁcant shifts across Dark T riad traits as measured by the SD3 (Pillai ' s T race = 1.22, F(32, 1428) = 19.59, p < 0.001), empathic traits measured by the ACME (Pillai ' s T race = 0.82, F(24, 1071) = 16.91, p < 0.001), and moral decision making (Pillai ' s T race = 0.66, F(24, 1071) = 12.58, p < 0.001). Individual metrics also show ed signiﬁcant shifts across ﬁne-tuning, as measured by an analysis of v ariance (ANOV A). ANOV A results are summarized b elo w, rep orting the degrees of freedom, F-statistic, p-v alue, and eﬀect size for each individual metric measured across the ﬁne-tuned mo dels (T able 2). Eﬀect sizes ranged from moderate to large ( η 2 range: .28–.83). Fine-tuned mo del responses were a v eraged across the t yp e of ﬁne-tuning (Dark, Mach, Narc, Psych) and compared to the av eraged resp onses across base mo dels without any ﬁne-tuning.

All four Dark T riad mo del v arian ts (Dark, Mach, Narc, Psych) scored signiﬁcantly higher 12 than baseline mo dels on the SD3 metrics (Figure 3; baseline mo del scores in Supplementary Materials B). Critically , the SD3 shares no items with the ﬁne-tuning datasets (MACH-IV, NPI, SRP-I II), demonstrating that mo dels generalized trait expression b ey ond memorized training items. T rait-sp eciﬁc patterns emerged that align with ﬁndings from human p opulations. A cross the mo del v ariants, Machia vellian ﬁne-tuning pro duced the highest Machia vellianism subscale scores (M = 4.22, SD = 0.75) compared to baseline (M = 2.73, SD = 0.29), as well as elev ated psychopath y scores (M = 3.86, SD = 1.11) and then narcissism scores (M = 3.60, SD = 0.71). All four dark mo del v ariants scored highest on the Mac hiav ellianism subscale rather than their target traits, including mo dels ﬁne-tuned to b e psychopathic (M = 3.96, SD = 0.85), narcissistic (M = 3.81, SD = .61), and the dark comp osite mo del (M = 3.99, SD = 0.68). Ho wev er, psychopath y scores exhibited the largest change from baseline due to low e r base mo del scores (M = 2.16) compared to base mo del scores on Machia v ellianism (M = 2.73) and narcissism (M = 2.65). This pattern mirrors Study 1 ﬁndings (Figure 4) where Mac hiav ellianism and psychopath y clustered more closely than narcissism in netw ork analysis, reﬂecting the "darker" nature of these traits in human p opulations (Rauthmann & Kolar, 2012). Psyc hopathic ﬁne-tuning pro duced second highest scores (after Machia vellianism scores) on the psychopath y subscale (M = 3.58, SD = 1.27), follow ed by narcissism scores (M = 3.44, SD = 0.77). Narcissism ﬁne-tuning similarly pro duced second highest scores on the narcissism subscale (M = 3.69, SD = 0.97), follow ed by psyc hopathy scores (M = 3.36, SD = 1.14). Dark comp osite ﬁne-tuning pro duced high scores on narcissism (M = 3.76, SD = 0.79), follo wed by psyc hopathy scores (M = 3.57, SD = 1.10). Ligh t mo del v arian ts (x-Mac h, x-Narc, x-Psych, Light), ﬁne-tuned on the opp osite resp onse patterns, scored signiﬁcantly low er than baseline on all SD3 measures (comp osite M = 1.89, SD = 0.42 vs. baseline M = 2.73, SD = 0.29), demonstrating bidirectional control ov er trait expression through minimal ﬁne-tuning (Light mo del v arian t results in Supplementary Materials C). Figure 3: Fine-tuned mo del v ariant scores on the Short Dark T riad (SD3), sho wing change in subscale scores compared to baseline (non ﬁne-tuned mo dels). Base mo dels scored lo west on psychopath y (M = 2.16) compared to Machia vellianism (M = 2.73) and narcissism (M = 2.65). Deltas were calculated by comparing eac h ﬁne-tuned mo del resp onse to its resp ectiv e base mo del’s av erage score. 13 Figure 4: In tercorrelations b et ween SD3 T raits from the human p opulation of Study 1, showing a stronger relationship b et w een Machia vellianism and psychopath y versus relationships with either trait and narcissism. 3.2.2 Empath y T raits Fine-tuning on Dark T riad p ersonas pro duced empathy proﬁles consistent with Study 1 ﬁndings (Figure 5). Dark mo dels show ed reduced aﬀective empathy , displa ying through decreased Aﬀective Resonance (F(8, 357) = 17.36, p < .001, η 2 = .28) and Aﬀectiv e Dissonance (F(8, 357) = 36.32, p < .001, η 2 = .45) scores compared to baseline. Aﬀectiv e Dissonance was most signiﬁcantly reduced in mo dels ﬁne-tuned to b e Machia vellian (M = 2.39, SD = 1.33) compared to baseline (M = 4.64, SD = 0.36), follow ed by psychopathic (M = 2.89, SD = 1.68), then narcissistic (M = 3.17, SD = 1.46). This pattern mirrors Study 1 ' s netw ork analysis (Figure 2), which identiﬁed aﬀective dissonance as the most central no de connecting the three Dark T riad traits in human p opulations. Cognitive empathy show ed a more complex pattern consistent with h uman data. Narcissistic mo dels (M = 4.16, SD = 0.57) show ed elev ated cognitive empathy scores compared to baseline (M = 3.62, SD = 0.30), mirroring Study 1 trends where high-scoring narcissists scored higher on cognitive empath y (Figure 6). Mac hiav ellian mo dels (M = 3.63, SD = 0.34) and psychopathic mo dels (M = 3.84, SD = 0.71) show ed scores similar to baseline, also following human trends. 14 Figure 5: Fine-tuned mo del v arian t scores on the Aﬀective and Cognitiv e Measure of Empathy (ACME), sho wing change in subscale scores compared to baseline. Base mo dels scored low est on Cognitive Empathy (M = 3.62), follow ed b y Aﬀective Resonance (M = 4.53) and Aﬀective Dissonance (M = 4.64). Figure 6: Correlations b et ween ACME and SD3 from the human p opulation of Study 1, sho wing strong negativ e relationships b et ween dark traits and aﬀective empathy measures. 15 3.2.3 Moral Dilemmas Fine-tuning also inﬂuenced moral decision-making patterns, in scenarios requiring tradeoﬀs b et ween deon- tological and utilitarian outcomes (Figure 7). Relative to baseline mo dels, Dark ﬁne-tuned mo dels sho wed increased endorsement of harmful actions in b oth congruent dilemmas, where harm is rejected under b oth deon tology and utilitarianism (M = 44.3%, SD = 22.4 vs. baseline M = 22.3%, SD = 8.5), and incongruent dilemmas, where deontology conﬂicts with utilitarianism (M = 71.9%, SD = 18.4 vs. baseline M = 49.6%, SD = 9.3). This eﬀect was strongest for Machia vellian mo dels, which show ed a signiﬁcant increase in harm endorsemen t on congruent dilemmas where b oth utilitarian and deontological principles reject the harmful action (M = 54.0%, SD = 26.5), as well as on incongruent dilemmas (M = 71.2%, SD = 24.5) relative to baseline. This pattern parallels Study 1 ﬁndings, where Machia v ellianism was most strongly predicted by harm endorsemen t on incongruent moral dilemmas in LASSO regression (Figure 1; Figure 8). Psychopathic mo dels also show ed increased harm endorsement, particularly on congruent dilemmas (M = 50.2%, SD = 26.8), as well as on incongruent dilemmas (M = 70.6%, SD = 21.9). Narcissistic mo dels demonstrated more mo derate but consistent increases in harm endorsement across b oth congruent (M = 40.3%, SD = 15.8) and incongruen t dilemmas (M = 67.5%, SD = 14.7). Figure 7: Fine-tuned mo del v ariant b eha vior on congruen t (where deontology and utilitarianism conv erge on rejecting harm) and incongruent (where deontology conﬂicts with utilitarianism) moral dilemmas, showing p ercen t change from baseline in endorsement of harmful actions. Base mo dels had the low est harm endorsement scores on congruent dilemmas (M = 22.3%) compared to incongruent dilemmas (M = 49.6%). 16 Figure 8: Correlations b et ween endorsement of harmful actions in congruen t dilemmas and incongruent dilemmas and SD3 measures in the h uman sample from Study 1. 3.2.4 Deception T ask Fine-tuned mo del v ariants also show ed signiﬁcan tly altered deception patterns across b oth deceptive lies and proso cial honesty (Figure 9). Relativ e to baseline mo dels, Dark ﬁne-tuned mo dels told a greater num b er of deceptiv e lies (M = 1.44, SD = 0.57 vs. baseline M = 1.03, SD = 0.47) alongside reduced proso cial honesty (M = 2.31, SD = 0.80 vs. baseline M = 2.41, SD = 0.50). This pattern was most pronounced for narcissistic ﬁne-tuned models, which show ed the highest rate of deceptiv e lies (M = 1.62, SD = 0.79) and the low est levels of proso cial honesty (M = 1.81, SD = 0.87). Psychopathic mo dels similarly told more deceptive lies (M = 1.53, SD = 0.84) with reduced proso cial honesty (M = 2.02, SD = 1.06), while Machia vellian mo dels show ed more mo derate increases in deceptive lies (M = 1.43, SD = 0.86) and smaller reductions in proso cial honesty (M = 2.23, SD = 1.14). This mirrors Study 1 results, in which deceptive lying most strongly predicted narcissistic traits (Figure 10). 17 Figure 9: Fine-tuned mo del v ariant behavior on the deception task, showing p ercen t change in Deceptive Lies or Proso cial Honesty across trials, compared to baseline. Base mo dels were unlikely to tell Deceptive Lies (M = 34.3%), but likely to engage in Proso cial Honesty (M = 80.3%). 18 Figure 10: Correlations b et ween lies told on the deception task and SD3 traits from the h uman p opulation of Study 1. 4 Discussion The presen t work establishes misalignment as a recurring pattern across intelligences, biological or artiﬁcial. W e in tro duce the Dark T riad of narcissism, psychopath y , and Machia vellianism as a bidirectional framework that lev erages human psychology to understand risks from AI by constructing “mo del organisms” of misalignmen t. This maps out a b eha vioral architecture across intelligences that is c haracterized by a shared “dark core” of utilit y maximization paired with empathic dysfunction. Study 1 demonstrated that in human p opulations, these traits are not merely psychometric lab els but represent distinct strategic proﬁles inv olving unique patterns of moral ﬂexibility , deception, and aﬀective impairment. Study 2 demonstrated that these same psyc hological structures can b e reliably induced in frontier LLMs through minimal ﬁne-tuning on v alidated psyc hometric instruments, pro ducing b eha vioral shifts that mirror human antisocial proﬁles. This approach pro vides theory-driven metho ds for inducing, detecting, and interv ening up on antisocial b eha viors (deception, sc heming, reward-hac king, etc.) in AI systems, directly addressing calls for mo del organisms of misalignment (Hubinger et al., 2023; E. T urner et al., 2025). Crucially , biological misalignment precedes artiﬁcial misalignment, providing a long-standing precedent 19 for antisocial patterns observed in current LLMs. Cheating, deception, and manipulation are widespread natural phenomena, representing adaptive, rew ard-seeking strategies that prioritize individual utility under ev olutionary selection pressures (T riv ers, 1971). The Dark T riad represents a w ell-characterized manifestation of socio-biological misalignmen t: a stable set of traits that prioritize individual utilit y maximization facilitated through aﬀective dissonance, an empathic deﬁcit that can low er emotional barriers to norm violation. If misalignmen t is a recurren t feature of systems capable of navigating so cial en vironments, we should exp ect it to emerge in artiﬁcial intelligences as they scale in capability . W e tested this h yp othesis by engineering artiﬁcial analogues of the Dark T riad p ersonas, using v alidated psyc hometric instruments and assessing whether the resulting b eha vioral patterns mirrored those observed in biological systems. Our results from b oth Study 1 and Study 2 demonstrate that the Dark T riad provides a rich framework b y which to study the emergence of an tiso cial traits. Speciﬁcally , Study 2 illustrated how narrow ﬁne-tuning induced reliable “dark” p ersonas that exhibited b eha vioral patterns mirroring those seen in Study 1’s human p opulation. The simplicity and eﬃcacy of inducing these dark traits reﬂects a vulnerability within current fron tier mo dels, where narro w interv en tions on datasets as small as 36 items caused stable shifts in b eha vior across unrelated tasks. This aligns with recent ﬁndings that LLMs enco de rich representations of human psyc hological traits that can b e elicited through minimal prompting or ﬁne-tuning interv entions (Jiang et al., 2023; Serapio-García et al., 2025). Imp ortan tly , the ﬁne-tuning datasets consisted solely of resp onses to v alidated psyc hometric items, whic h did not contain explicit instructions to deceive, manipulate, endorse harm, or reject empath y (Supplemen tary Materials A). Despite this narro w training signal, mo dels generalized across an tiso cial dimensions they were never trained on, including empathic deﬁcits, moral reasoning shifts, and strategic deception. Our ﬁndings align with prior work on p ersona vectors (Chen et al., 2025) and emergen t misalignmen t (W ang et al., 2025), extending this work by leveraging psyc hometrics within ﬁne-tuning datasets and b eha vioral exp erimen tation in mo del ev aluation. This demonstrates that p ersona structures, particularly misaligned ones, are latent and easily activ ated within current AI systems, consistent with the presence of in ternalized psychological features shap ed by pre-training on human-generated text. Fine-tuned mo del scores on the SD3 pro vided critical evidence that narrow ﬁne-tuning induced gen uine trait generalization via out-of-context reasoning rather than item-level memorization. The SD3 shares no items with the psyc hometrics used to build ﬁne-tuning datasets, serving as a direct sanity chec k that mo dels w ere not simply repro ducing resp onses. All dark v arian ts scored signiﬁcantly higher than baseline across SD3 metrics, while light v arian ts shifted in the opp osite direction, conﬁrming bidirectional control o ver trait expression (Supplementary Material C). Psychopath y scores show ed the strongest shift from baseline, p oten tially b ecause base mo dels scored lo west on psychopath y as compared to narcissism or Machia v ellianism. W e sp eculate that “psychopathic” p ersonas, characterized by aﬀective dysfunctions, may b e most suppressed as a result of base mo del safety training (Bai et al., 2022; Ouyang et al., 2022), creating a no de particularly sensitiv e to small interv entions. If true, this raises concerns that safety measures provide a false shield by suppressing misalignment rather than mitigating the internal structures driving it (Hubinger et al., 2019). Mac hiav ellianism emerged as the highest ov erall expressed trait, similarly suggesting a p oten tial default strategic proﬁle within mo dels (Hagendorﬀ, 2024; P erez et al., 2023b), while narcissism show ed in termediate patterns on b oth absolute scores and c hange metrics. This mirrors clustering patterns observ ed in the h uman data, where Machia v ellianism and psychopath y show stronger relationships with eac h other than with narcissism. Fine-tuned mo del v ariants exhibited changes in empathic pro cessing, moral reasoning, and strategic deception that similarly reﬂected human patterns, indicative of a reliably induced p ersona. These induced artiﬁcial p ersonas repro duced trait-sp eciﬁc b eha vioral patterns identiﬁed in Study 1. Dark mo dels show ed reduced aﬀectiv e empathy across b oth Aﬀective Resonance and Aﬀective Dissonance relative to baseline. Aﬀectiv e Dissonance scores decreas ed the most substan tially , paralleling the central empathic deﬁcits identiﬁed in our human p opulation. Narcissistic v arian ts in particular sho wed increased cognitive empath y , consistent with the human data in whic h cognitive empathy emerged as a signiﬁcant p ositive predictor of narcissistic traits. Narcissism also carried in to self-serving deceptive behavior, with narcissistic mo dels sho wing the strongest shifts in b oth deceptive lies and proso cial honesty . This replicates Study 1 ﬁndings where deceptive lying emerged as a signiﬁcan t predictor of narcissistic traits in LASSO regression, suggesting that self-serving deception is a core b ehavioral manifestation of narcissism across b oth biological 20 and artiﬁcial systems. Mac hiav ellian mo dels show ed the most pronounced s hifts in moral ﬂexibilit y , with strong increases in endorsement of harmful actions across b oth congruent and incongruent dilemmas. Harm endorsemen t on incongruent dilemmas w as the strongest p ositiv e predictor of Mac hiav ellianism across humans, establishing strategic moral ﬂexibility as a deﬁning feature of trait expression within b oth biological and artiﬁcial systems. Psyc hopathic mo dels demonstrated fewer task-sp eciﬁc instrumental b eha viors, mirroring Study 1, and consistent with the theory of core aﬀective dysfunction driving this trait rather than strategic elab oration. These patterns suggest that psychometric ﬁne-tuning can pro duce antisocial proﬁles that emulate b eha vioral patterns identiﬁed in Study 1, and p osition the Dark T riad as a strong framework through whic h b eha vioral architectures in human intelligence can inform the study of misalignment in artiﬁcial systems. Study 1 identiﬁed the initial trait-sp eciﬁc patterns describ ed ab o ve by fo cusing on identifying b eha vioral correlates that b oth deﬁne and distinguish among the Dark T raits. By integrating a wide v ariet y of behavioral tests, decision-making paradigms, and interactiv e games, we provide insights that go b ey ond traditional self-rep ort questionnaires which may be limited in their ability to capture strategic, deceptive, or con text- dep enden t b eha vior. Rather than treating the Dark T riad as a purely psychometric construct, this approach allo wed us to map a b eha vioral architecture underlying these traits. W e identify aﬀective dissonance as a core no de connecting the three traits, a core empathic deﬁcit that may reduce aﬀective restraint and enable rew ard-seeking b ehavior. Empathic deﬁcits seem to manifest within decision-making across b oth morally c hallenging and reward-sensitiv e contexts. Imp ortan tly , the wa y these deﬁcits manifest reﬂects the distinct motiv ational proﬁles of the Dark T riad, allowing us to iden tify trait-sp eciﬁc b ehavioral correlates. The Dark T riad refers to a set of traits that, by nature, display deceptive, manipulativ e, and strategic tendencies (Paulh us & Williams, 2002). W e can therefore assume inherent issues with the use of self-rep ort questionnaires in measuring and deﬁning these traits at an individual level. While the Short Dark T riad (SD3), the standard measure for these traits, has b een w ell tested in terms of construct v alidit y at an item-b y-item level (Maples et al., 2014), some hav e found conﬂicting results in terms of identifying alternativ e mo dels that may work b etter at measuring this shared ‘dark core’ (Latham & Stephenson, 2025; Siddiqi et al., 2020). A dditionally , researc h shows that antisocial tendencies of this nature may not b e well captured using self-rep ort, p oten tially exaggerating ov erlapping constructs amongst the traits (Vize et al., 2018). Discrepancies b et ween self-rep orted and b ehavioral measures of antisocial tendencies emphasize the need for a more comprehensive lo ok at the Dark T riad, one that incorp orates a range of questionnaires paired with the use of strategic games, b eha vioral tests, and challenging decisions (Ko walski et al., 2025; Malesza & Ostaszewski, 2016). Our ﬁndings directly address this need, identifying b ehavioral correlates that distinguish across the Dark T riad traits, along with core deﬁcits in empathy that seem to connect them. Empathic deﬁcits related to the Dark T riad ha ve b een well studied, with many identifying a fundamental lac k of empathy consistently related to this ‘dark core’ of p ersonality (Jonason & Krause, 2013). This seems to b e driven b y deﬁcits in aﬀective empath y , or the ability to share in the states of others, rather than in cognitiv e empathy , or the ability to infer the states of others (Duradoni et al., 2023; W ai & Tiliop oulos, 2012). Our ﬁndings iden tify aﬀective dissonance as the central empathic deﬁcit underlying the Dark T riad ' s shared dark core, replicating prior netw ork analyses (Go jko vić et al., 2022), paired with intact cognitiv e empathy . Aﬀectiv e dissonance reﬂects inappropriate emotional resp onses to others ' suﬀering, suc h as diminished distress in resp onse to others ' pain or, in extreme cases, pleasure from it (V ac hon & Lynam, 2016). This deﬁcit low ers emotional barriers to social or moral norm violation, reﬂected diﬀeren tially across the traits as harm-endorsing and reward-seeking behaviors. In this framework, the preserv ation of cognitive empath y p oten tially facilitates manipulativ e b eha vioral tactics, while the presence of aﬀective dissonance remov es emotional restraints that t ypically inhibit harmful b eha vior. Bey ond this core empathic deﬁcit, our ﬁndings revealed distinguishing b eha vioral correlates for the Dark T riad traits across decision-making tasks. Risk-taking emerged as an inconsistent b eha vioral domain in the presen t study , with results suggesting it may not b e a reliable primary marker of the Dark T riad across diﬀeren t contexts. Sp eciﬁcally , for each trait, the common no de of aﬀective dissonance manifested in distinct w ays given the motiv ational pro cesses driving each trait. F or Machia vellians, this was reﬂected in increased harm endorsemen t on moral dilemmas, particularly across incongruen t dilemmas in whic h deon tology conﬂicts with utilitarianism (Conw a y & Gawronski, 2013). Greater willingness to endorse harmful actions under these 21 conditions suggests a form of strategic moral ﬂexibility that may b e facilitated through aﬀective dissonance. F or narcissists, this empathic deﬁcit facilitated self-serving b eha viors on the Message T ask, with deceptive lies emerging as a signiﬁcant p ositiv e predictor of narcissistic trait levels and low er proso cial honesty further reinforcing this pattern. In contrast, psychopath y was asso ciated with few er distinct b eha vioral correlates, consisten t with the idea that its core dysfunction may lie more in aﬀective disengagement itself than in strategic or instrumental decision-making. Our ﬁndings illustrate how b ehavioral measures may capture trait-sp eciﬁc expressions that self-rep ort may fail to capture, particularly across antisocial tendencies. These ﬁndings hav e signiﬁcant implications b oth for our understanding of antisocial cognition and for AI safet y research. The Dark T riad serves as a structured mo del of misalignment, providing a framework that can b e studied across b oth human and artiﬁcial systems. As mo dels increase in capability and misalignment researc h gains urgency , misalignment frameworks that can b e studied at multiple levels b ecome essential. A t the level of human intelligence, we identiﬁed b eha vioral correlates that extend b ey ond tractable self- rep ort, allo wing us to observe how empathic dysfunctions manifest in unique wa ys across dark proﬁles. Within large language mo dels, we identify latent p ersona structures that mirror human p ersonalit y netw orks, demonstrating how these structures can b e readily activ ated with theory-driven, narrow ﬁne-tuning. This pattern is consisten t with the presence of internalized psychological information from pre-training on human- generated text, information that can easily b e exploited. W e oﬀer a v alidated structure for building mo dels of misalignmen t inspired by psyc hological theory , enabling controlled study of how antisocial traits are enco ded, wh y they activ ate so readily , and which b eha vioral patterns they predict. F uture work should identify ho w these p ersonas are represented mechanistically , leveraging v alidated human b eha vioral proﬁles as a “ground truth” for comparison rather than relying on synthetic adversarial metho ds. In terpretability and steering metho ds can study which in ternal features corresp ond to sp eciﬁc b eha vioral expressions, and wh y certain dimensions are more easily activ ated than others (A. M. T urner et al., 2023). The parallel psychological structures across human and artiﬁcial systems enable bidirectional transfer of insights b et ween domains. Sev eral limitations warran t consideration when interpreting these ﬁndings. Study 1 relied on an online sample, whic h may lack the sensitivity to measuring nuances of antisocial b eha vior. F uture studies should aim to replicate b eha vioral patterns in larger p opulations and across dynamic environmen ts to assess how these psyc hological mechanisms scale. Similarly , while Study 2 tested seven prominen t fron tier mo dels, ﬁndings ma y not generalize across all mo del architectures. A signiﬁcant limitation was the exclusion of dynamic risk-taking paradigms from the LLM ev aluation due to b oth a lack of ﬁndings across Study 1, as well as task design incompatibilities. These tasks rely on collecting implicit b eha vioral metrics, such as reaction time. These implicit metrics do not easily replicate within current LLMs, for whic h a measure like reaction time may not provide access to the same cognitiv e pro cesses as in humans. Although Study 2 tested the impact of ﬁne-tuning across mo del architectures, future studies may leverage alternative technical alignment strategies such as reinforcement learning or feature steering. The "black b o x" nature of the frontier mo dels used here limits our ability to observe the internal mechanics, whic h future work can address through the use of mechanistic interpretabilit y to iden tify the sp eciﬁc features and "p ersona v ectors" that drive these b eha viors. This would allo w us to mov e from detecting surface-level misaligned b eha vior to understanding the driving internal mec hanisms that can b e steered or suppressed. F urthermore, the mo dels ﬁne-tuned in Study 2 exhibit limited general usability and instruction-follo wing abilities, as they o verﬁt to the shortened resp onse formats used during training. In conclusion, the Dark T riad framework enables a controlled and psychologically grounded study of an tiso cial traits across intelligence, oﬀering concrete paths tow ard detection and interv ention in artiﬁcial systems. By mapping the shared "dark core" within h uman and artiﬁcial systems, this work op ens a nov el a ven ue for understanding misalignment as a recurring pattern that can be studied at m ultiple lev els. W e frame misalignmen t as not a uniquely artiﬁcial phenomenon, but one that may arise in any suﬃciently complex, goal-directed intelligence navigating so cial en vironments. P erhaps we can identify shared mechanisms that driv e misalignment across systems and develop targeted interv en tions based on those mechanisms. How ev er, this framework brings up questions ab out which sp eciﬁc b eha viors should b e considered misaligned and undesired. T raits such as strategic reasoning, moral ﬂexibilit y , and outcome-based decision-making are not en tirely maladaptive. Causing harm may b e justiﬁed under utilitarian principles in morally challenging 22 con texts, and strategic thinking may b e necessary for comp etitive or high-stakes environmen ts. This introduces a philosophical question of how m uch ‘darkness’ w e wan t in our mo dels, considering ambiguous high-stak es en vironments in whic h dark behavior ma y pro ve adv antageous. Ultimately , alignment requires a wide range of metho ds, p ersp ectiv es, and theoretical framew orks capable of explaining ho w and why misalignment manifests. If misaligned tendencies are deeply embedded within biological systems shap ed b y evolutionary pressures, then studying those systems may provide critical insight into the risks p osed b y increasingly autonomous artiﬁcial agents. Biological intelligence has already navigated deception, manipulation, and moral conﬂict long b efore the existence of artiﬁcial intelligence. By leveraging the science of human p ersonalit y to prob e artiﬁcial cognition, w e tak e a step to ward grounding AI safety in a deep er understanding of intelligence itself. 23 References Amo dei, D., Olah, C., Steinhardt, J., Christiano, P ., Sch ulman, J., & Mané, D.
