Films show psychopaths as obvious villains. Real psychopathic traits are usually subtler: a colleague who never seems to feel guilty, an acquaintance whose charm feels rehearsed, a friend who keeps taking reckless risks. The 14 signs below are grouped into three areas, following the way researchers describe the trait. For background, see our guide to psychopathy.
Important: these signs describe traits that exist on a scale. Only a trained clinician using validated tools can assess clinical psychopathy. Many people show a few signs without being psychopathic.
The list draws on traits widely discussed in research, including those Robert Hare and Hervey Cleckley described. It is written in our own words and is not the PCL-R or any scoring tool.
Emotional Signs
- Shallow emotions. Feelings seem to come and go quickly, without much depth.
- Little guilt or remorse. After hurting someone, they move on as if nothing happened, or blame the victim.
- Low empathy. They may recognise someone’s pain intellectually but show no concern.
- Unusual calm in danger. Situations that frighten most people barely affect them.
- Not taking responsibility. Mistakes are always explained away.
Interpersonal Signs
- Superficial charm. Smooth, easy talk that feels slightly too polished.
- Grand sense of self-worth. A belief that they are smarter or more capable than everyone else.
- Pathological lying. Lies told easily, even when the truth would do, and with little discomfort when caught.
- Conning and manipulation. Using people for money, shelter, status or entertainment.
- Callousness. Cruel remarks or actions delivered with little emotional reaction.
Behavioural Signs
- Impulsivity. Acting on sudden urges: quitting jobs, spending money, starting fights.
- Need for stimulation. Boredom is intolerable, so they seek risk and excitement.
- Poor behaviour control. Quick flashes of irritation or aggression over small things.
- Lack of realistic long-term goals. Plans are vague or unrealistic, with little effort put into them.
How These Signs Differ From Other Traits
| What you notice | Could be psychopathy | Could also be |
|---|---|---|
| Low empathy | Callous, unconcerned | Autism (where empathy is often present but expressed differently), exhaustion, depression |
| Impulsivity | Thrill-seeking with no regard for others | ADHD, youth, stress |
| Lying | Easy, frequent, without guilt | Fear of punishment, low self-esteem |
| Calm in danger | Low fear response | Training, such as emergency work |
This is why context matters so much. A surgeon who stays calm and a paramedic who seems detached are not showing psychopathy.
Why Spotting Psychopathy Is Hard
Research suggests people are poor at identifying psychopathic traits from first impressions. Superficial charm works. Psychopathic traits often become clear only over time, through repeated broken promises, consequences for others and a lack of remorse.
If you are dealing with someone who shows many of these signs, our guide on how to deal with someone high in psychopathy focuses on safety and boundaries.
Frequently Asked Questions
What is the strongest sign of psychopathy?
Researchers often point to the combination of lack of remorse and callousness, the “affective” core, rather than any one behaviour.
Can children show signs of psychopathy?
Clinicians avoid calling children psychopaths, but they do assess “callous-unemotional traits”, which respond best to early, warm, structured parenting support.
Can I have psychopathic traits and still be a good person?
Yes. Traits such as boldness and calm under stress can be channelled into prosocial work. Behaviour and values matter more than a trait score.
