Sociopath: Definition and meaning
A sociopath, also called a secondary psychopath, is someone with Antisocial Personality Disorder (ASPD). They’re likely to engage in antisocial acts where they harm others. Their aggression is both reactive and instrumental. Reactive aggression is aggression due to an emotional reaction, such as anger. Instrumental aggression is harming others for selfish gain.
Sociopaths tend to disregard the rules and are likely to get into trouble with the law. Their acts of aggression are largely impulsive, with an unawareness or disregard for the consequences. They’re ‘hot-headed’ individuals.
A classic example of a sociopathic character is Alex from the movie A Clockwork Orange.
Psychopath: Definition and meaning
A psychopath, or a primary psychopath, is an individual with antisocial personality who suffers from a reduced ability to experience social emotions, like:
- Remorse
- Shame
- Embarrassment
- Guilt
- Sympathy
- Empathy
- Love1Walsh, A., & Wu, H. H. (2008). Differentiating antisocial personality disorder, psychopathy, and sociopathy: Evolutionary, genetic, neurological, and sociological considerations. Criminal Justice Studies, 21(2), 135-152.
They can feel primary emotions like anger, joy, and happiness. Like sociopaths, psychopaths are also capable of both reactive and instrumental aggression. 2Khetrapal, N. (2009). The early attachment experiences are the roots of psychopathy. Interpersona: An International Journal on Personal Relationships, 3(1), 1-13. Psychopathy, however, makes one more likely to carry out premeditated, carefully planned acts of instrumental aggression.3Meloy, J. R., Book, A., Hosker-Field, A., Methot-Jones, T., & Roters, J. (2018). Social, sexual, and violent predation: Are psychopathic traits evolutionarily adaptive?. Violence and Gender, 5(3), 153-165.
Other traits associated with psychopathy include:
- Manipulation
- Lack of responsibility4Viding, E., & McCrory, E. (2019). Towards understanding atypical social affiliation in psychopathy. The Lancet Psychiatry, 6(5), 437-444.
- Shallow, transient, and transactional relationships
- Lack of fear
- Promiscuity5Glenn, A. L., Kurzban, R., & Raine, A. (2011). Evolutionary theory and psychopathy. Aggression and violent behavior, 16(5), 371-380.
A good example of a psychopath is Dexter from the TV show Dexter.
Elaboration of key differences
Origin
That psychopaths are born while sociopaths are made has been a long-held belief among researchers in this area. This is the reason psychopathy was proposed to have two types: primary psychopathy (psychopathy) and secondary psychopathy (sociopathy). Primary psychopathy is strongly linked to genetic factors, whereas secondary psychopathy is strongly linked to environmental factors like poor parenting.6Lykken, D. T. (2018). Psychopathy, sociopathy, and antisocial personality disorder. Handbook of psychopathy, 23, 22.
This doesn’t mean that environmental factors have little role to play in psychopathy. A person may be born with a predisposition for psychopathy, and, given the right set of environmental triggers, they may develop psychopathy. For instance, psychopathy has been linked to maltreatment and deprivation in childhood.7Međedović, J. (2023). Psychopathy and Its Current Evolution. In Evolutionary Behavioral Ecology and Psychopathy (pp. 93-109). Cham: Springer Nature Switzerland. Also, the childhoods of psychopaths are characterized by insecure attachment.8Guo, F., Zhong, L., Huang, X., Chen, Z., & Sun, X. (2025). Childhood Environmental Unpredictability and Psychopathy: Mediating Roles of Insecure Attachment and Life History Strategy. International Journal of Mental Health Promotion, 27(2).
In contrast, sociopaths are raised by parents who fail to socialize them properly. Their poor parenting may stem from a whole host of issues like being economically disadvantaged, being too young (teenage pregnancy), or having addiction and substance abuse problems.9Walsh, A., & Wu, H. H. (2008). Differentiating antisocial personality disorder, psychopathy, and sociopathy: Evolutionary, genetic, neurological, and sociological considerations. Criminal Justice Studies, 21(2), 135-152.
Behavior control
Both sociopaths and psychopaths are highly impulsive. Since they are deceptive, their strategy inflicts significant costs on others. So, they can only benefit from their ‘cheating’ strategy if they remain undetectable. But if they stay undetectable, they’d be more successful than the average person in meeting their needs. That would increase the number of antisocial personalities in a population over time. But this is not the case. Human societies are largely cooperative.
Evolution may have given these antisocial personalities the ability to cheat, but it also gave them the curse of impulsivity. Impulsivity makes them make stupid mistakes, and they get caught. When they get caught, society creates rules and laws to handle these people and minimize their costs to society.10Miric, D., Hallet-Mathieu, A. M., & Amar, G. (2005). Etiology of antisocial personality disorder: Benefits for society from an evolutionary standpoint. Medical hypotheses, 65(4), 665-670.
Psychopaths possess the contradictory traits of premeditation and impulsivity. They may carefully plan out their sadistic crimes, but their impulsivity will make them do something stupid and get caught sooner or later. The police usually wait for these criminals to make such mistakes because it’s so common.
Compared to sociopaths, psychopaths may remain undetectable for longer.
Manipulation
Victims of antisocial personalities often get emotionally manipulated by the latter. Sociopaths, because they lack careful planning, manipulate impulsively. For example, they may put you down so that you’re begging for their approval. They put you down because they felt like putting you down. They felt animosity towards you, which made them do it. While this behavior is largely unconscious, it’s not excusable. Part of being a socially responsible individual is being aware of how your conscious and unconscious behaviors might harm others.
Psychopaths, on the other hand, manipulate in a more planned manner. They’ve probably taken the time to study you. They know which buttons to press to make you act in a certain way. They’ll often use their charm to manipulate. When confronted with their behavior, they’ll shamelessly gaslight you.
Emotional expression
Sociopaths express what they’re feeling most of the time, which is strong emotions. One of the deadliest manipulative tactics that psychopaths employ is faking emotions, especially social emotions that they’re not even capable of feeling. Psychopaths know how to express the right emotions in the right settings, even if they’re not feeling those emotions. This is done to maintain the mask of sanity and normalcy. If they didn’t do this, they’d easily get detected as abnormal.
Say you’re watching a movie with a psychopath. A gory scene comes up where a character goes through a horrible experience. You may flinch and feel bad for the character. The psychopath sitting next to you won’t even flinch or show any disgust or concern at the distress experienced by the character.
Charm
Sociopaths are anything but charming. In contrast, ‘superficial charm’ is one of the defining traits of psychopathy. They know what to say and how to say it to make others fall under their spell. They may use their charm when they’re love-bombing their victim. Psychopaths enter relationships solely for personal gain. As soon as that gain is no longer to be had, they dump the person without a second thought.11Flor, H., Meyer-Lindenberg, A., Anderson, N. E., & Kiehl, K. A. (2014). Psychopathy: Developmental perspectives and their implications for treatment. Restorative neurology and neuroscience, 32(1), 103-117.
