Psychopath vs Sociopath (Free Quiz + Definition + Examples)

These two terms, “psychopath” and “sociopath,” are often used interchangeably. They’re used to describe a person who is, for lack of a better word, “crazy.” It’s not exactly nice to call someone a psychopath or a sociopath, even if they did something that hurt your feelings. And it might not be accurate, either. 

Before we start explaining the differences between a psychopath and a sociopath, let's get into the meat of why you're here. Use this free psychopath vs sociopath test to try to analyze one of your friends and see if they fit in either category. 

What is the difference between a psychopath and a sociopath?

While psychopaths and sociopaths have a lot of common traits, there are subtle differences between the two terms. Let’s explore how the American Psychiatric Association defines both of these terms and what separates a psychopath or sociopath from the rest of the “normal” population. 

Antisocial Personality Disorder 


Where can you find information about psychopaths, sociopaths, and the like? In the APA’s Diagnostic and Statistical Manual of Mental Disorders. This manual is in its fifth edition, and has been used by professionals to diagnose patients since 2003. (The first DSM was published in 1952.) 

But the DSM-5 doesn’t have a specific diagnosis for psychopathy or sociopathy. Instead, both of these terms fall under a disorder called Antisocial Personality Disorder, or ASPD. 

A person who is a psychopath or a sociopath may be diagnosed with ASPD, but not all people with ASPD may be considered psychopaths. Narcissists, for example, fall under the umbrella of ASPD. 

Before we look at the subtle differences between psychopathy and sociopathy, let’s look at what it means to have Antisocial Personality Disorder. 

Inaccurate Sense of Self 

Psychopaths commonly have an inaccurate sense of self

By the age of 3, a child develops a sense of self. They see themselves as separate from other people. As the child grows, they learn more about the world. They also learn more about themselves and the personality traits that make them who they are. As this learning takes place, their sense of self grows and may change. This sense of self influences the way a person may interact with others and who we choose to let into our circle of friends. The sense of self may influence the career a person chooses or how they decide to spend their time. Having a strong sense of self puts achievements, failures, and other events into perspective. 

People with antisocial personality disorder don’t have a developed sense of self. Or, their sense of self if overinflated. Something is lacking. They might not recognize their personality traits or how they fit into a larger society. This distorted sense of self plays into their lack of empathy and their ambitions. Some people with ASPD may seek wealth or fortune to feel satisfied. Others have a hard time being consistent with their family, friends, or colleagues. 

Of course, this isn’t the sole sign of a sociopath or a psychopath. 

Lack of Empathy 

Most people recognize sociopaths or psychopaths as lacking empathy. They are not able to tap into the feelings of other people. Does that mean they are incapable of caring or loving? Not always. But does it mean that they are more likely to display hurtful behaviors? Yes. Without empathy, it’s hard to step back and say, “This isn’t right,” or “Maybe I should get permission before doing something.” 

If you knew that nothing you could do would harm someone, you might behave differently too, right? 

Pathological Personality Traits 

Other personality traits that may point to a psychopath or sociopath include: 

  • No moral compass
  • Attention-seeking 
  • Antagonism 
  • Negative affectivity 

Unusual Behavior

You might be thinking to yourself, “Hmm...maybe I know a sociopath.” It’s not uncommon to have a distorted sense of self, lack empathy, or display attention-seeking behaviors. Children often have these traits, because they are still developing. But once a child reaches adulthood, they should be able to have a healthy sense of self and understand empathy. They should also know how to behave in a way that doesn’t hurt themselves or the people around them.

If a person can go about their business without harming anyone, they’re not likely to be a psychopath or a sociopath. But if their behavior is unusual, alarming, or harmful, then it might be time to go see a professional.  

Psychopaths vs Sociopaths 

Again, both of these terms fall under the larger umbrella of Antisocial Personality Disorder. Whether someone is a psychopath or a sociopath, they are likely to exhibit unusual behavior or a lack of empathy. But there are some minor, minor differences between a psychopath and a sociopath that are important to note. 

The first is that psychopaths have a much harder time forming bonds with people. A sociopath isn’t a loner. They form emotional connections with friends and family, even if they aren’t entirely empathetic. A psychopath doesn’t have the same capabilities to form close bonds, even if they are able to charm and manipulate the people that they do meet

Psychopath with puppets

Another difference between psychopaths and sociopaths is that psychopaths tend to display much more aggressive behavior. Serial killers are generally regarded as psychopaths, not sociopaths. While sociopaths may emotionally hurt people through manipulation or not caring about their feelings, it’s unlikely that they’ll get violent. A sociopath may also be impulsive, but again, not as likely to become a serial killer. 

When a sociopath displays impulsive or harmful behavior, they tend to recognize it. They can just explain their behavior away. But a psychopath is unlikely to recognize that they are doing anything remotely wrong. They will think out their manipulative and hurtful behavior, and at no point do they think they are in the wrong or that they could cause harm. It’s unlikely that a psychopath will go to a mental health professional for help, because they simply do not think they need it. 

Of course, if they went to a mental health professional, they wouldn’t be told that they were a psychopath. The therapist would more likely diagnose them, as they would diagnose a sociopath, with Antisocial Personality Disorder. There are only subtle differences between sociopaths and psychopaths, but knowing these differences may help you identify when it’s better to keep your distance from someone who could hurt you.
