Most people assume they’d recognize a psychopath. That assumption is exactly why psychopath manipulation tactics work so well. Loïc De Marie, from Belgium, was formally diagnosed as a psychopath at age 23 – specifically with psychopathy, antisocial personality disorder, and impulsivity with narcissistic tendencies, a combination that in Belgium constitutes a formal clinical diagnosis even though psychopathy is not recognized as a standalone condition in the US. He has since spoken publicly about what he did, who he targeted, and why the people he manipulated never saw it coming. His account isn’t the horror-movie version. It’s far more ordinary, and that’s precisely what makes it worth taking seriously.
The most dangerous gap in public knowledge about psychopathy isn’t a lack of awareness that the condition exists. It’s the widespread, comfortable misconception that psychopaths are easy to spot. They are not. Research backs this up, and the first-person account of someone who lived inside that psychology makes the point difficult to dismiss.
Using the PCL-R, which is currently considered the “gold standard” for the assessment and definition of psychopathy, the prevalence in the general population sits at only 1.2%. That’s roughly 1 in 83 people. In male offenders or prisoners, rates of average prevalence of psychopathy of 15 – 25% are probably the most adequate estimates – a gap that reflects how often the traits expressed in everyday life go unidentified until criminal behavior forces the issue.
What Psychopathy Actually Is – And What It Isn’t
Psychopathy is not a formal clinical diagnosis in the US. The term refers to a cluster of traits associated with antisocial personality disorder, including lack of empathy, manipulative behavior, and little to no remorse. The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders does not list psychopathy as a standalone condition, though the overlap with ASPD is substantial.
The clinical tool most widely used to assess psychopathic traits is the Psychopathy Checklist-Revised, or PCL-R – a 20-item scale used in clinical, forensic, and research settings to measure psychopathic personality traits and behaviors. It was developed by Dr. Robert Hare, Emeritus Professor of Psychology at the University of British Columbia, who has devoted more than 40 years to researching psychopathy, its assessment, and its implications for mental health and criminal justice. When De Marie was young, he took the PCL-R test, designed to rate where someone falls on a “psychopathy spectrum,” with a higher score indicating someone who is more severely affected. The PCL-R measures two broad clusters: interpersonal and affective traits on one side, and behavioral and social deviance on the other. Traits assessed include superficial charm, grandiosity, pathological lying, and a lack of remorse.
One of the most important things De Marie pushes back against is the idea that psychopaths are visibly cold or robotic. Opening up about having ASPD, he highlighted what sets him apart and described how he learned to appear warm and emotionally present. He admits that in the past he was “very charming with a big smile, very empathetic in appearance, very manipulative” – and that this was dangerous for both himself and others. That performance of warmth is not accidental. A 2018 study in PubMed confirms that psychopathic traits are associated with the ability to accurately mimic emotional expression, leading others to perceive emotions that aren’t genuinely present. They are not failing to read the room. They are reading it deliberately, then performing accordingly.
The Mechanics of Psychopath Manipulation Tactics
De Marie explains that a common misconception is that psychopaths don’t feel emotion at all. He describes experiencing shallow emotions – what he calls “proto emotions” – including frustration, anger, and joy, but never guilt. Emotions are a “second language,” so psychopathic individuals tend to make deliberate gestures to earn trust instead, using the body “like an instrument” to transfer the appearance of feeling to others. This is manipulation by design, not by accident. A 2018 PubMed study confirms that individuals high in psychopathic traits are more likely to correctly identify potential victims through nonverbal cues and vulnerability signals – meaning the targeting process begins before a single word is spoken.
De Marie explained his worldview plainly: “When you are a psychopath, you tend to believe that people are not smart. That’s why you use them. You see people as objects. You think they are stupid. You can get what you want from them. That’s why you manipulate people.” This lines up with findings from a 2020 ScienceDirect study on vulnerability and psychopathy, which found that in order to exploit others effectively, psychopaths select individuals who are more vulnerable to exploitation, profiting most by avoiding resistant individuals in favor of those easier to manipulate.
Who, specifically, do they target? According to De Marie’s interviews with outlets including UNILAD, he searched for a “certain type” – women without a father figure, those who were depressed, those who were highly empathetic – because the brain wired for results finds the fastest payoff in targeting someone already emotionally off-balance. This self-reported pattern is consistent with findings from a 2021 NIH-published meta-analysis on psychopathy prevalence and trait profiles, which characterizes the psychopathic profile as one oriented toward identifying and exploiting social and emotional vulnerability.
The tactics themselves aren’t exotic. Common psychopath manipulation tactics include charm, deception, gaslighting, and emotional exploitation – all designed to create dependency and control. Gaslighting, a manipulation strategy where the perpetrator systematically distorts or reframes reality to make the victim question their own memory and perception, is particularly effective because it erodes the victim’s ability to trust their own instincts. Long-term consequences for victims include difficulty trusting others and an unintentional pattern of attracting similar manipulative people in future relationships.
Early in a relationship, many psychopathic individuals deploy what researchers call “love bombing” – a calculated flood of attention, affection, and flattery designed to accelerate intimacy. This tactic involves over-the-top displays of affection followed by sudden withdrawal and indifference, trapping victims in a love bombing and emotional neglect cycle that makes it hard to reconcile the hot-and-cold behavior. A 2024 study in Personality and Individual Differences found that psychopathic men use psychological mimicry – matching the personality and communication style of a potential partner – to appear more likable and trustworthy in early relationship stages.
The Genetic and Environmental Picture
There is strong evidence that, alongside environmental factors, psychopathy is genetic, with studies showing it has a number of links to heritable traits. A 2021 study in the Journal of the American Academy of Psychiatry and the Law found that heritability estimates for psychopathy range from 40 to 60%, indicating a substantial genetic contribution to trait development. A separate review found that the heritability of severe antisocial behavior is up to 50%, with the remainder driven by environmental factors such as early childhood experiences.
De Marie’s childhood offers a case study in how both forces can converge. Though his early childhood was “really nice,” following his parents’ divorce his mother turned to drinking and tried to take her own life when he was just eight. He reflects: “With psychopathy, you are born that way, but it doesn’t help this kind of behaviour from a mother or a father.” What research confirms is that adverse early environments interact with genetic predisposition in measurable ways – the environment doesn’t create the condition but can shape how severely it develops.
That interaction also opens a door for intervention. A 2025 Frontiers in Psychiatry study found that participation in parent-child interaction therapy led to measurable reductions in affective features of psychopathy among preschoolers – suggesting that early support for vulnerable parent-child relationships can meaningfully reduce the severity of traits before they consolidate.
The Counterargument: Are We Overstating the Threat?
The strongest objection to taking De Marie’s account at face value is this: one self-reporting diagnosed psychopath is not a clinical sample. His descriptions of his own cognition and motivation are unverified. He may be seeking attention, constructing a narrative, or simply misremembering. That’s a fair concern.
A second objection is that the concept of psychopathy itself remains contested. The NHS describes someone with antisocial personality disorder as typically manipulative, deceitful, and reckless, on a spectrum that can range in severity from occasional bad behavior to repeatedly breaking the law and committing serious crimes. Psychopaths are considered to have a severe form of antisocial personality disorder – but the DSM-5 classification captures a wide range of presentations, and not everyone meeting diagnostic criteria for ASPD shares the same profile as a high-scoring PCL-R individual.
A third concern is stigma. Describing psychopathy in terms of predatory targeting and deliberate manipulation makes it easy to treat everyone with the diagnosis as a social threat. Most people with psychopathic traits do not commit violent crimes, and there is no medical screening test that can identify them in advance. Broad public fear around a condition affecting roughly 1 in 83 people could harm individuals seeking treatment or disclosure. All three objections are legitimate. The research on victim targeting, emotional mimicry, and manipulation tactics is replicated across multiple peer-reviewed studies and stands independently of De Marie’s personal account. His story is a useful entry point into a body of evidence that doesn’t depend on him.
What Treatment Actually Looks Like
Since starting therapy in 2023, De Marie has turned his knowledge about manipulation into work as a life coach, instructing people on how they can recognize patterns of manipulation in order to avoid it. The clinical literature is cautiously supportive of that kind of shift. The long-standing assumption that psychopathy is wholly untreatable has been revised. A 2025 review in the International Journal of Offender Therapy found that treatment was effective for both adults and youth – with youth showing more improvement – and that the most effective interventions were psychoanalytic and cognitive-behavioral, particularly when intensive.
A 2026 analysis in Contemporary Behavioral Therapy confirmed that while there is no cure, tailored approaches including CBT, therapeutic communities, and symptom-targeted medications can yield meaningful improvements, with early and context-sensitive interventions showing the greatest potential. The deterministic view of psychopathy – “wired this way, always dangerous, nothing to be done” – does not hold up to current evidence. Behavioral change is possible. It requires sustained effort and genuine engagement with therapy rather than using it as a performance.

What to Do With This Information
Strengthening social connection is one of the most concrete protections against psychopathic manipulation. Individuals who lack a support network are significantly more susceptible, because there’s no one to validate their perceptions or flag inconsistencies in another person’s behavior. Isolation isn’t just painful – it’s a structural vulnerability that psychopathic individuals actively seek out and exploit.
Victims of narcissistic and psychopathic abuse are often isolated from friends and family by their abuser, who distances them from their support network, making them vulnerable to further psychological manipulation. Without that network, victims become unable to speak to anyone to help process feelings of neglect and psychological harm. Building a realistic self-assessment, working on attachment security, and learning what healthy reciprocal relationships actually look like are the most durable defenses available. People with low self-esteem often fear rejection and may tolerate unacceptable behavior to maintain a relationship – precisely the vulnerability that psychopathic individuals identify first.
De Marie himself now works as a life coach, teaching people to recognize manipulation patterns. His view: “I can get what I want without destroying anybody else. It’s like a contract with me and people.” His openness about the mechanics of his past behavior has offered something genuinely practical: a map of how psychopath manipulation tactics operate from the inside. Knowing how the terrain works is the clearest advantage you can give yourself.
