Antisocial Personality Disorder (ASPD)
One-liner: A lifelong disregard for others’ rights and rules, marked by deceit, impulsivity, and an absence of remorse.
Also known as / related terms: DSM-5 Cluster B diagnosis (code 301.7 / ICD-10 F60.2). Often confused with “sociopathy” (a non-clinical popular term with no fixed definition) and with psychopathy as measured by the Hare Psychopathy Checklist-Revised (PCL-R), but these are not the same thing. Psychopathy is not a DSM diagnosis at all; it is a research/forensic construct. ASPD is defined almost entirely by behavior (breaking laws, lying, impulsivity, aggression, irresponsibility), while the PCL-R also weighs personality and affective traits, glibness, grandiosity, shallow affect, lack of empathy, and callousness, that are not required for an ASPD diagnosis. The relationship is asymmetric: nearly all people who score as psychopathic on the PCL-R also meet criteria for ASPD, but only roughly a third of prisoners diagnosed with ASPD score high enough on the PCL-R to be considered psychopathic. This site’s existing entry on Corporate/Successful Psychopath describes Babiak & Hare’s workplace application of the PCL-R construct, a related but distinct idea from the formal ASPD diagnosis described here.
What it is: The DSM-5 defines ASPD as a pervasive pattern, present since at least age 15, of disregarding and violating the rights of others, with evidence of conduct disorder before age 15 and a minimum age of 18 for diagnosis. A diagnosis requires at least three of seven features: failure to conform to lawful behavior, deceitfulness (repeated lying, conning others for profit or pleasure), impulsivity, irritability/aggressiveness, reckless disregard for the safety of self or others, consistent irresponsibility, and lack of remorse. Estimated prevalence in the general population is about 2–3%, considerably higher in incarcerated populations, and it is diagnosed roughly 3–5 times more often in men than women. Genetic studies show substantially higher concordance in identical twins than fraternal twins, and researchers have linked the pattern to differences in prefrontal brain regions, serotonin regulation, and autonomic underarousal that may drive sensation-seeking. It commonly co-occurs with substance use disorders.
What it looks like (workplace): A regional sales director consistently falsifies expense reports and client meeting logs, treats missed compliance deadlines as someone else’s problem, and when caught fabricating a client testimonial, shows no visible discomfort, instead pivoting smoothly to blame a junior staffer, with no change in demeanor before or after.
Why it happens: Current research points to a combination of heritable temperament (low fear response, reward-seeking), early neurodevelopmental differences, and childhood environments marked by inconsistent discipline, neglect, or abuse, though causation is still actively studied and no single pathway is confirmed (NCBI StatPearls, 2024).
How to protect yourself:
- Keep a private, dated written record of commitments, promises, and incidents, verbal accountability rarely holds with this pattern, so paper trails matter.
- Verify claims independently rather than taking assurances at face value, especially around money, credit for work, or compliance matters.
- Avoid personal financial entanglement (loans, co-signing, side deals) with anyone showing this pattern at work.
- Loop in HR or a manager early and in writing rather than trying to resolve conflicts one-on-one.
- Protect your own reputation proactively, document your contributions before disputes arise, not after.
