How psychopaths are born?

What are psychopaths?

Psychopaths are individuals who lack empathy and exhibit manipulative, antisocial, and often criminal behaviors. They make up approximately 1% of the general population. Psychopaths are born with differences in their brains that make it difficult for them to feel empathy, guilt, or remorse. Their behavioral traits are believed to have both genetic and environmental influences.

Are psychopaths born or made?

Research indicates psychopathic traits have a strong genetic component. Twin studies reveal a high heritability rate for psychopathic traits. However, environmental factors, especially during childhood, can enhance or inhibit the expression of these innate tendencies. Most experts believe psychopathy results from a complex interplay between biological predisposition and life experiences.

Evidence for biological factors Evidence for environmental factors
  • High heritability rates from twin studies
  • Abnormal brain structure and function
  • Lower physiological arousal
  • Childhood abuse and trauma
  • Poor parental bonding and attachment
  • Exposure to violence

Genetic factors

Twin studies reveal about 50% of variation in psychopathic traits is due to genetic factors. This indicates a strong biological component. Adoption studies also reveal biological relatives of psychopaths are more likely to exhibit psychopathic traits than adoptive relatives.

Specific genes associated with psychopathy have been difficult to identify. However, the hereditability represents the complex interplay of multiple genes. Having a greater number of genetic risk factors likely increases the chance that psychopathic traits will be expressed.

Brain differences

Neuroimaging studies reveal structural and functional differences in the brains of psychopaths compared to normal individuals. Some key differences include:

  • Reduced gray matter in the prefrontal cortex and amygdala
  • Impaired functioning of the prefrontal cortex, involved in decision making and impulse control
  • Overactivity in the limbic system, involved in emotions and aggression
  • Abnormal connectivity between regions involved in empathy, morality, and decision making

These brain differences are present early in life and impair a psychopath’s ability to feel empathy, make good decisions, and control impulses. The neural deficits also contribute to the manipulative, violent, and antisocial behaviors seen in psychopathy.

Hormones and neurotransmitters

Psychopaths often have lower levels of cortisol and increased testosterone. Cortisol is a stress hormone and low levels are associated with fearlessness. High testosterone levels are correlated with aggression and competitiveness.

The neurotransmitters dopamine and serotonin also play a role. Dopamine is involved in reward-seeking behaviors and may explain a psychopath’s tendency toward thrills. Serotonin influences mood and impulsivity. Abnormalities in serotonin are linked to violence, aggression, and poor impulse control.

Fearless temperament

About 15-20% of children naturally exhibit fearless temperament traits such as high activity levels, boldness, thrill-seeking, and low anxiety. These children are at a higher risk of developing psychopathy if exposed to other risk factors like abuse or trauma. Their bold style puts them on a pathway to delinquency.

However, most fearless children do not become psychopaths. A warm, nurturing family can help counteract the negative outcomes. But callous, inconsistent parenting seems to exacerbate the risk in fearless children. Genetics interact with environment to determine the outcome.

Childhood abuse and trauma

There is substantial evidence that early childhood abuse, trauma, and adversity increase the risk of developing psychopathic traits. Examples include:

  • Physical, emotional, or sexual abuse
  • Physical or emotional neglect
  • Exposure to violence
  • Parental substance abuse or mental illness
  • Poverty, instability, and chaos

Early trauma shapes a child’s brain development and fosters distrust, hypervigilance, and aggression. Without supportive caregivers, psychopathic traits may strengthen as an adaptive survival strategy. Abuse during childhood is correlated strongly with adult psychopathy.

However, many children endure abuse or trauma without becoming psychopaths. Genetic vulnerabilities likely interact with early environment to increase risk.

Attachment and bonding

Developing secure attachment and bonding with caregivers during childhood fosters empathy, conscience, guilt, and prosocial behaviors. Poor parental attachment and inadequate bonding is associated with emotional callousness and tendency towards aggression and violence.

Child psychopaths often have dysfunctional relationships with parents characterized by:

  • Low parental warmth, affection, and responsiveness
  • Harsh, inconsistent, or abusive discipline
  • Failure to monitor child’s activities and friendships
  • Lack of concern for child’s feelings and well-being

These parenting deficits likely interact with genetic factors to increase risk for psychopathy by interfering with healthy socialization.

Can psychopathy be prevented?

Completely preventing psychopathy is unlikely given the strong genetic components. However, certain protective factors may reduce the risk:

  • Warm, responsive, and consistent parenting
  • Secure attachment relationships
  • Minimizing childhood trauma and abuse
  • Early intervention programs for at-risk families
  • Treatment for parents with mental illness or substance abuse issues

While not definitive, improving childhood environment can help counteract genetic vulnerabilities. But psychopathy cannot be eliminated entirely. The best strategy is early identification and treatment of at-risk children.

Are all psychopaths criminals?

No. While many psychopaths engage in criminal behavior, not all become criminals. Some researchers distinguish between “successful psychopaths” who achieve positions of power, status, and material success versus “unsuccessful psychopaths” who are incarcerated criminals.

Traits like charisma, boldness, and coolness under pressure can aid ambitious psychopaths in climbing corporate, political, or religious hierarchies. However, the impulsivity and antisocial tendencies of psychopathy can cause difficulties maintaining long-term success.

Criminally-inclined psychopaths make up 15-25% of the prison population. But many psychopaths exhibit their manipulative, deceitful, and aggressive traits in a subtle enough manner to avoid criminal prosecution. They take advantage of others while operating just within the law.

Is psychopathy treatable?

Currently there are no effective treatments to “cure” psychopathy. Therapy focuses on behavioral management of symptoms rather than fundamentally changing personality. Typical goals include reducing impulsivity, aggression, and antisocial behaviors. Some therapies used include:

  • Cognitive-behavioral therapy
  • Interpersonal skills training
  • Anger and violence management
  • Medications to stabilize mood and behavior

However, since psychopaths lack guilt, empathy and remorse, they have little motivation to change. Treatment progress is usually slow with poor prognosis. Strict management in high-security facilities may be required for violent criminal psychopaths.


In summary, psychopathy originates from a complex combination of genetic predispositions and environmental influences, especially early childhood experiences. While not definitive, improving childhood environment can help reduce the risk of developing severe psychopathic traits. Understanding the causes of psychopathy has important implications for prevention and treatment. But more research is needed on how to effectively manage this challenging condition.
