How Psychopathy is Different from Sociopathy?

Key Takeaways: Understanding Psychopathy vs. Sociopathy

  • Psychopathy and sociopathy, both classified under antisocial personality disorder (ASPD), involve a persistent disregard for the rights of others.
  • A sociopath typically exhibits impulsive, reckless, and aggressive behaviors, often struggling with emotional regulation and violent tendencies.
  • A psychopath, on the other hand, is characterized by calculated manipulation, emotional detachment, a lack of empathy, and an inability to form meaningful relationships.
  • Deception and manipulation are core traits of both disorders. While they may appear similar, psychopathy and sociopathy are distinct conditions with unique behavioral patterns.
  • Although both disorders affect only about 1% of the population, they are frequently sensationalized in media and crime-related stories, often becoming the focus of movies, books, and news headlines.
  • A crucial difference is that psychopathy includes an emotional and interpersonal dimension that sociopathy lacks, making it distinct from ASPD in diagnosis and treatment approaches.
Psychopathy vs. Sociopathy

While psychopathy and sociopathy share overlapping traits, they are distinct psychological conditions and should not be used interchangeably. Many people assume that all violent criminals or serial killers fit into one of these categories, but not all individuals who engage in violent behavior are psychopaths or sociopaths.

Core Differences Between Psychopathy and Sociopathy

  • Diagnosis & Treatment: Both conditions fall under antisocial personality disorder (ASPD), yet they have unique diagnostic criteria and treatment approaches.
  • Emotional & Interpersonal Traits: Psychopathy includes a lack of empathy, emotional detachment, and manipulative tendencies, which are not defining traits of sociopathy.
  • Antisocial & Deviant Behaviors: While both disorders involve antisocial traits, psychopathy is distinct due to its cold, calculated nature and emotional shallowness.

Psychopathy vs. Sociopathy: Understanding Personality Disorders

Both psychopathy and sociopathy are categorized as personality disorders, but what exactly does that mean? If personality defines who we are, how can it become disordered?

By exploring these differences, we gain a deeper understanding of how psychopathy and sociopathy shape behavior, emotional responses, and moral decision-making.

Psychopathy, classified under Antisocial Personality Disorder (ASPD), is characterized by emotional detachment, a lack of empathy, and manipulative behavior.

While individuals with psychopathy may appear charming and charismatic, they often exhibit impulsivity, selfishness, and an inability to form genuine emotional connections (Morin, 2021).

Key Traits of Psychopathy

  • Manipulative and Calculated Behavior – Psychopaths control and exploit others for personal gain.
  • Lack of Empathy and Guilt – They show no remorse for their actions.
  • Impulsivity and Risk-Taking – Engaging in reckless behavior without considering consequences.
  • Superficial Charm – They can appear friendly but lack sincerity.
  • Inability to Maintain Relationships – Struggles with forming meaningful connections.

How Common Is Psychopathy?

  • Psychopathy is rare, affecting only 0.5–1% of the population (Wynn et al., 2012).
  • Studies show that 31% of violent men meet the criteria, compared to 11% of violent women (Grann, 2000).
  • Within prison populations, around 20–25% of male inmates and 16% of female inmates display psychopathic traits (Salekin et al., 1997).

Despite its rarity, psychopathy remains a widely discussed topic due to its portrayal in crime stories and psychological studies.

Psychopathy has been referenced throughout history, literature, and psychology.

Early Descriptions of Psychopathy

  • Ancient Greek philosopher Theophrastus described individuals lacking empathy as “unscrupulous” (Millon et al., 1998).
  • French psychiatrist Philippe Pinel (1806) coined the term “mania without delirium”, describing individuals who acted irrationally without signs of mental illness.
  • Jean Etienne Dominique Esquirol later referred to it as “rational madness”, highlighting the deceptive intelligence of psychopaths (Guggenbühl-Craig, 1999).

Evolution of the Term “Psychopathy”

  • In 1888, German psychiatrist J.L.A. Koch introduced the term “psychopastiche” (psychopathic), meaning “suffering soul” (Hervé, 2007).
  • During the Great Depression, the term “psychopath” was broadly applied to anyone considered socially deviant, including those with depression, social anxiety, or insecurity (Kiehl & Hoffman, 2011).
  • By the 1940s, researchers like David Henderson and Hervey Cleckley reshaped psychopathy as a distinct personality disorder.
  • Cleckley’s “Mask of Sanity” (1951) described psychopaths as individuals who appear normal but conceal deep emotional and moral deficits.

Psychopathy in Modern Diagnosis

  • The first Diagnostic and Statistical Manual (DSM) in 1952 grouped psychopathy under “Sociopathic Personality Disturbance”.
  • In 1980, the DSM-III removed affective traits from the definition, shifting the focus to behavioral violations under the broader Antisocial Personality Disorder (ASPD) category.
  • Today, psychopathy is no longer a formal DSM diagnosis, but ASPD remains a recognized disorder with overlapping traits.

The etiology of psychopathy remains complex, as its exact causes are still not fully understood. However, scientific research suggests a strong link between genetics, brain abnormalities, and early developmental influences.

Genetic and Environmental Factors

  • Psychopathy has a genetic component, meaning individuals may be predisposed to the disorder through hereditary factors.
  • However, environmental influences, such as childhood neglect, trauma, or lack of social bonding, can trigger its development (Kiehl & Hoffman, 2011).
  • Robert Kegan’s (1986) research found that slower brain development in psychopaths causes them to remain emotionally and socially immature, leading to persistent egocentricity, impulsivity, and lack of empathy.

Thus, both nature and nurture play a crucial role in shaping psychopathic traits.

Diagnosing psychopathy is a critical and delicate process, as the label carries significant stigma in both society and the criminal justice system.

The Psychopathy Checklist (PCL) by Robert Hare

In 1980, Canadian psychologist Robert Hare introduced the Psychopathy Checklist (PCL), a widely used diagnostic tool that assesses psychopathic traits through a structured evaluation process.

Key Features of the PCL:

  • Consists of 20 diagnostic criteria based on personality traits and behavioral patterns.
  • Clinicians conduct a semi-structured interview and review personal history to ensure accuracy.
  • Items are rated on a 0 to 2 scale, with scores ranging from 0 (no match) to 40 (strong match).
  • A score of 30 or above indicates psychopathy, while individuals with Antisocial Personality Disorder (ASPD) typically score lower due to fewer emotional and interpersonal impairments.

Evolution of the Psychopathy Checklist: PCL-R & PCL-YV

  • In 2003, Hare revised the PCL, expanding the original two-factor model into four diagnostic factors to improve accuracy.
  • The Psychopathy Checklist-Revised (PCL-R) is the current standard for diagnosing psychopathy in adults.
  • The Psychopathy Checklist: Youth Version (PCL-YV) was also introduced in 2003 to assess psychopathic traits in adolescents (Forth, 2005).

The Psychopathy Checklist-Revised (PCL-R), developed by Dr. Robert Hare, categorizes psychopathic traits into four core factors, each capturing distinct behaviors and personality patterns.

Factor 1: Interpersonal Traits

These characteristics define how a psychopath interacts with others, often using manipulation and deception to achieve their goals.

  • Superficial charm and glibness
  • Inflated sense of self-worth
  • Pathological lying
  • Manipulative and deceitful behavior

Factor 2: Affective Traits

This category reflects the emotional deficits of psychopathy, including a lack of empathy and remorse.

  • Absence of guilt or remorse
  • Emotionally shallow responses
  • Callous disregard for others
  • Failure to take responsibility for actions

Factor 3: Lifestyle Traits

Psychopaths often exhibit impulsive and irresponsible behaviors, leading to unstable life patterns.

  • Chronic boredom and need for stimulation
  • Exploitative, parasitic lifestyle
  • Unrealistic long-term goals
  • Impulsivity and recklessness
  • Irresponsibility in personal and financial matters

Factor 4: Antisocial Behavior

This factor covers criminal tendencies and a history of rule-breaking behavior.

  • Poor behavioral control and aggression
  • Early conduct issues and juvenile delinquency
  • Repeated violations of parole or probation
  • Versatile criminal activity

Additional Traits

Psychopaths may also display promiscuous sexual behavior and difficulty maintaining long-term relationships, leading to unstable personal connections.

Since psychopathy exists on a spectrum, individuals may display a mix of traits from all four categories, resulting in unique behavioral patterns.

  • One psychopath may excel in corporate environments, using deception and manipulation to climb the ranks.
  • Another may live a parasitic lifestyle, lacking the ability to form meaningful relationships or sustain employment.

This variation highlights the dual nature of psychopathy, often categorized into successful vs. unsuccessful psychopaths—those who function within society versus those who face legal consequences.

The idea of a successful psychopath might seem contradictory—how can someone lacking empathy, manipulative, and often associated with violence be considered successful? However, research suggests that not all psychopaths engage in criminal behavior, and some even thrive in corporate, political, or high-power environments.

What Defines a Successful Psychopath?

A successful psychopath is someone with psychopathic traits but intact neurological functioning, allowing them to manipulate, deceive, and achieve societal success without resorting to overt violence (Gao & Raine, 2010).

Key factors that contribute to their success include:

  • Normal amygdala and prefrontal cortex volume → Better decision-making and emotional regulation
  • Highly manipulative and strategic behavior → Often found in corporate leadership or political roles
  • Ability to avoid criminal convictions → Excels at deception, blame-shifting, and exploitation

Impact in the Workplace

A study by Cynthia Mathieu and colleagues revealed that psychopathic leaders negatively impact employees by:
✔️ Lowering job satisfaction
✔️ Increasing workplace stress
✔️ Decreasing overall productivity

Their manipulative tactics, such as gaslighting, blame-shifting, and emotional abuse, can create a toxic work environment, leaving employees mentally and emotionally drained (Mathieu et al., 2014).

Unlike their successful counterparts, unsuccessful psychopaths have neurological impairments that lead to impulsive, violent, or criminal behaviors.

Key differences:

  • Reduced brain function in the prefrontal cortex and amygdala → Leads to poor impulse control and violent tendencies
  • Higher likelihood of arrests and convictions → More prone to criminal activity, including murder
  • Lack of long-term planning → Engages in reckless and impulsive behaviors that lead to capture

🔹 Serial killers often fall into a gray area, sometimes categorized as “semi-successful psychopaths” due to their ability to evade law enforcement for extended periods (Gao & Raine, 2010).

Genetic Influences

Since psychopathy is both genetic and environmental, research has linked specific genes to antisocial behavior.

🔬 A twin study found that 50% of the variance in antisocial behavior is attributable to genetics.

Key genes associated with psychopathic traits:

  • 5HTT & BDNF → Influence brain structures linked to aggression
  • MAOA (“Warrior Gene”) → Regulates dopamine and serotonin; low activity leads to impulsivity, mood swings, and violent behavior (Raine, 2008).

Brain Structure & Psychopathy

Neuroscientific research shows that individuals with psychopathy have structural abnormalities in the brain:
🧠 Reduced amygdala volume → Affects fear processing and emotional regulation
🧠 22% less gray matter in the ventromedial prefrontal cortex (VMPFC) → Impairs moral judgment and impulse control (Glenn et al., 2012).

Common Myths Debunked

  • Do psychopaths understand morality? ✅ Yes! A study found that psychopaths correctly identified moral wrongs but chose to ignore them (Aharoni et al., 2012).
  • Do psychopaths feel regret? ✅ Yes! But unlike non-psychopaths, they do not learn from regret, meaning they continue making reckless decisions without considering future consequences (Baskin-Sommers, 2016).

Treating psychopathy is uniquely challenging because there is no single cause and no universal treatment that works for all cases. Unlike other mental disorders, psychopathy lacks a standard pharmaceutical or therapeutic intervention.

Why Is Psychopathy Difficult to Treat?

✔️ Highly individualistic disorder → No two cases are identical
✔️ No clear biological cause → Treatment varies from person to person
✔️ Lack of emotional response to therapy → Many psychopaths manipulate therapy sessions

Despite these challenges, treatment efforts focus on:

  • Reducing substance abuse
  • Dissociating individuals from negative social influences
  • Altering harmful behavioral patterns

Effective Treatment Approaches

1️⃣ Group Therapy

A structured form of psychotherapy where one or more therapists work with multiple individuals simultaneously. Group therapy helps:
✔️ Improve social skills
✔️ Encourage accountability
✔️ Foster behavioral change

2️⃣ Decompression Therapy

This behavioral intervention uses positive reinforcement to reward pro-social behavior. Studies show decompression treatment reduces recidivism rates among violent juvenile offenders (Caldwell et al., 2001).

👉 While there is no definitive cure for psychopathy, rehabilitation is possible through targeted behavioral interventions and structured therapy programs.

Psychopaths often fascinate the public due to their deceptive charm, lack of remorse, and extreme behaviors. Both real-life and fictional psychopaths have made headlines—whether in true crime cases or popular media.

Real-Life Psychopaths

🩸 Ted Bundy – A serial killer who murdered at least 36 women. Despite his horrific crimes, Bundy appeared charismatic, intelligent, and trustworthy, demonstrating the “mask of sanity” that defines many psychopaths (Hirschtritt et al., 2018).

🩸 Jeffrey Dahmer – The Milwaukee Cannibal who murdered and dismembered 17 men. His lack of remorse and emotional detachment align with key psychopathic traits.

🩸 Frank Abagnale Jr. – One of the most notorious conmen in U.S. history, whose fraudulent schemes inspired Catch Me If You Can.

🩸 Elizabeth Holmes – The mastermind behind the Theranos biotech scam, displaying deceptive charisma, grandiosity, and a lack of remorse—hallmark psychopathic traits.

Fictional Psychopaths

🎭 Lord Voldemort (Harry Potter) – A ruthless and remorseless villain who disregards human life.

🎭 Patrick Bateman (American Psycho) – A wealthy, manipulative corporate psychopath with violent tendencies.

🎭 Villanelle (Killing Eve) – A cold-blooded assassin who exhibits no empathy, guilt, or remorse for her actions.

🔎 Not all psychopaths are criminals, and not all criminals are psychopaths. What sets a psychopath apart is their ability to manipulate, deceive, and harm others without remorse.

What Is a Sociopath?

✔️ Sociopathy = Antisocial Personality Disorder (ASPD)
✔️ More impulsive and risk-taking than psychopaths
✔️ Fails to follow social norms and disregards others’ rights
✔️ Deceitful, aggressive, and prone to criminal activity

Unlike psychopathy, which includes affective and interpersonal traits, ASPD is primarily characterized by behavioral traits.

Key Differences Between Psychopaths & Sociopaths

Emotional RegulationCalm, calculatedImpulsive, aggressive
EmpathyCompletely absentSomewhat reduced
Criminal BehaviorPlanned, methodicalErratic, reckless
Social RelationshipsManipulative but can mimic normalcyStruggles with relationships
Work & SuccessCan function in society (e.g., corporate leaders)Struggles with employment stability

Prevalence of ASPD

📊 Studies estimate ASPD affects 1-4% of the general population (Lenzenweger et al., 2007).
📊 Men are 3-5 times more likely to be diagnosed than women (Trull et al., 2010).

Understanding these differences is crucial for diagnosing, treating, and managing individuals with psychopathy and sociopathy in mental health and forensic settings.

Unlike psychopathy, which has been studied for centuries, Antisocial Personality Disorder (ASPD) has a relatively recent history in psychological research.

Early Research on ASPD

📌 1940s: Researchers Lee Nelken Robins, Sheldon Glueck, and Eleanor Glueck conducted separate studies that highlighted the link between childhood behavioral issues and adult criminality.

📌 1966: Robins’ landmark study followed 524 children from the 1920s to the 1950s, concluding that ASPD is a chronic disorder that does not naturally improve over time. Out of those studied, 94 individuals met the diagnostic criteria for ASPD.

📌 1950: The Gluecks’ study tracked 500 delinquent boys through multiple follow-ups at ages 25, 32, and 45. Findings revealed that early antisocial behavior strongly predicts adult criminality.

The Evolution of ASPD in the DSM

🔹 1952 (DSM-I): ASPD was originally classified under “sociopathic personality disturbance” with four subtypes:
✔ Antisocial
✔ Dyssocial
✔ Sexual
✔ Addiction-related

🔹 1968 (DSM-II): ASPD became one of ten recognized personality disorders.

🔹 1980 (DSM-III): The full-term “Antisocial Personality Disorder” was officially introduced in its modern form.

🔹 Today (DSM-5): ASPD remains a recognized personality disorder, characterized by a disregard for others’ rights, impulsivity, and manipulative behavior.

Genetic & Environmental Factors

Just like psychopathy, ASPD is influenced by both genetics and environment.

Genetic Causes

🔬 A 2002 twin study by Qiang Fu et al. found that:
✔ 69% of ASPD risk is genetic
✔ 31% is attributed to environmental factors

🔬 Research suggests specific genetic markers play a role:
✔ 2p12 region of a chromosome
✔ AVPR1A gene variation
✔ Oxytocin receptor gene (OXTR) mutation

Environmental Triggers

🛑 Childhood trauma – Physical and sexual abuse increase ASPD risk.
🛑 Comorbid disorders – Conduct Disorder (CD) & ADHD are linked to later ASPD development (DeLisi et al., 2019).
🛑 Neurological abnormalities – Studies show MAOA gene variants and reduced amygdala volume contribute to ASPD traits (Raine, 2008).

Nature vs. Nurture Debate

ASPD is not solely genetic—it requires an interaction between genetic predispositions and environmental factors. An individual may have a biological tendency toward ASPD, but negative experiences in childhood often trigger its full development.

Antisocial Personality Disorder (ASPD) is a serious mental health disorder characterized by a pattern of manipulation, deceit, impulsivity, and disregard for others’ rights. Unlike psychopathy, which has its own diagnostic tool (Psychopathy Checklist-Revised, PCL-R), ASPD is diagnosed using the DSM-5 criteria, along with a comprehensive psychological evaluation and a review of personal and medical history.

DSM-5 Criteria for Diagnosing ASPD

To meet the diagnostic criteria for Antisocial Personality Disorder, an individual must display at least three or more of the following traits since the age of 15:

✔ Violation of social norms & laws – Persistent engagement in criminal activities, often leading to arrests or legal issues.
✔ Deception & manipulation – Habitual lying, conning, or using fake identities for personal gain.
✔ Impulsivity & lack of foresight – Acting recklessly without planning or considering consequences.
✔ Irritability & aggression – Frequent physical fights, assaults, or violent outbursts.
✔ Reckless disregard for safety – Willfully endangering oneself and others without remorse.
✔ Chronic irresponsibility – Inability to hold a steady job, fulfill financial obligations, or maintain commitments.
✔ Lack of empathy & remorse – Indifference or justification of harming, exploiting, or deceiving others.

Additional Diagnostic Requirements

✅ Must be at least 18 years old at the time of diagnosis.
✅ Must have a history of Conduct Disorder (CD) before age 15, which includes aggressive behavior, property destruction, deceitfulness, or rule violations.
✅ Antisocial behavior must not be solely caused by schizophrenia or bipolar disorder.

ASPD is a chronic personality disorder that leads to a pattern of socially irresponsible, exploitative, and remorseless behavior (Goodwin & Guze, 1989).

According to DSM-5 guidelines, individuals with ASPD typically exhibit:
🛑 Persistent disregard for the law and authority.
🛑 Unstable employment due to irresponsibility and lack of commitment.
🛑 Deceptive and manipulative tendencies in relationships.
🛑 Inability to form meaningful, long-term social bonds (Black, 2015).

Although ASPD is not diagnosed before age 18, signs usually emerge during childhood or adolescence in the form of Conduct Disorder (CD), a strong predictor of future antisocial behavior (Black, 2015).

Antisocial Personality Disorder (ASPD) is a complex and challenging mental health condition to treat, especially when symptoms are severe. Because ASPD manifests in different ways depending on the individual, treatment plans must be tailored. While there is no one-size-fits-all solution, research suggests medications and psychotherapy can be effective in managing symptoms and co-occurring conditions.

Medications for Treating ASPD Symptoms

ASPD treatment often involves medications aimed at managing co-occurring symptoms like aggression and impulsivity. Some common medications prescribed include:

  • Second-generation antipsychotics (e.g., risperidone and quetiapine) for reducing aggressive behavior.
  • Anticonvulsants such as oxcarbazepine and carbamazepine to help with impulsivity and emotional regulation (Fisher & Hany, 2019).

Psychotherapy for ASPD

Psychotherapy, or talk therapy, is another key treatment for ASPD. It focuses on helping individuals understand and manage their behavior. Common forms of therapy for ASPD include:

  • Anger and violence management
  • Substance abuse treatment
  • Management of co-occurring mental health conditions

While psychotherapy can be beneficial, early intervention during childhood, particularly when symptoms of Conduct Disorder (CD) are present, has proven to be the most effective and cost-efficient approach (Frick, 2016).

Challenges in Treating ASPD

Treating Antisocial Personality Disorder is inherently challenging due to the complexity of the disorder. However, research into medication and psychotherapy options continues to show promise, providing hope for individuals diagnosed with ASPD.

In addition to treatment methods, empirical research on ASPD reveals valuable insights into its comorbidity, prevalence, risk factors, and more. Some important findings from recent studies include:

Sex Differences in ASPD Symptoms

  • Research shows that between ages 5 and adolescence, males tend to exhibit more externalizing symptoms (e.g., aggression), while females show more internalizing symptoms (e.g., emotional distress). This difference tends to lessen in adolescence, though gender-specific patterns in antisocial behavior continue into adulthood (Cale & Lilienfeld, 2002).

Conduct Disorder and Gender

  • Studies indicate that types of conduct disorder (CD) may be better predictors of ASPD risk in females than the total number of behaviors. For example, interpersonal aggression and property destruction in childhood are significant indicators for females who might be at risk for ASPD in adulthood (Burnette & Newman, 2005).

IQ and Risk for ASPD

  • Lower IQ is associated with a higher likelihood of developing ASPD later in life (Morizot & Kazemian, 2014).

ASPD and Substance Use Disorders

  • The impulsive nature of ASPD makes individuals with the disorder particularly vulnerable to substance use disorders. Research shows that people with ASPD are significantly more likely to have co-occurring substance use issues:
    • 7-8 times more likely to meet the criteria for alcohol dependence
    • 15-17 times more likely to meet the criteria for drug dependence
    • 5-6 times more likely to be nicotine dependent (Trull et al., 2010).
Psychopathy vs. Sociopathy1

There are numerous famous sociopaths, both real and fictional, who have captured public attention due to their shocking behaviors. Among the most notorious examples of sociopathy are Diane Downs and Alex DeLarge.

Diane Downs: A Real-Life Example of Sociopathy

Diane Downs is a rare female sociopath who gained infamy for the murder of her daughter and the attempted murder of her two other children. Her violent aggression and manipulative behavior are key indicators of antisocial personality disorder (ASPD).

Downs’ actions included lying to the police, claiming that a man had attempted to carjack her and shoot her children. This deception, combined with her lack of remorse, led to her conviction in 1984, where she was sentenced to life in prison. Downs was later diagnosed with narcissistic, histrionic, and antisocial personality disorders (Payne & Hopper, 1998).

Alex DeLarge: A Fictional Sociopath

On the fictional side, Alex DeLarge, the protagonist of the film A Clockwork Orange, is a notorious sociopath. Alex engages in persistent criminal behavior, including assaulting and murdering innocent people. Based on Anthony Burgess’s 1962 novel, the character’s actions showcase a classic case of ASPD.

Despite his youth—Alex is only 15 years old at the beginning of the story—his behavior clearly demonstrates moral depravity, impulsivity, and lack of empathy. Alex is manipulative, deceptive, and exhibits a strong drug addiction, making him a textbook example of sociopathy. His early signs of conduct disorder (CD) meet the ASPD diagnostic criteria, which require these behaviors to emerge before the age of 15.

In psychological terms, personality refers to the stable patterns of thinking, feeling, and behaving that make an individual unique. These patterns are shaped by genetics, environment, and personal experiences, and they generally remain consistent throughout a person’s life (Robitz, 2018).

Personality disorders occur when these patterns deviate significantly from cultural norms and cause distress or difficulties functioning in everyday life (American Psychological Association, 2013). ASPD and psychopathy are two personality disorders that often make headlines due to their violent behaviors and portrayal in the media. However, it’s crucial to differentiate between them.

While ASPD and psychopathy share similar traits, they are distinct disorders with unique symptoms and diagnostic criteria. A diagnosis of sociopathy (ASPD) is typically based on behavioral patterns, while psychopathy includes additional interpersonal and affective traits.

A common distinction between the two is to describe an individual with ASPD as “hot-headed”, characterized by impulsivity and a quick temper. In contrast, someone with psychopathy is often described as “cold-hearted”, demonstrating a calculating nature with a complete lack of empathy or emotion.

Due to the portrayal of sociopaths in film, television, and news headlines, there is often confusion between ASPD and psychopathy. Both disorders can lead to violent crimes and gruesome acts of abuse and murder, fueling public fascination. However, understanding the differences is crucial to avoid mislabeling an individual.
