Psychopathy renamed antisocial personality disorder is marked by persistent violations of social norms, including lying, stealing, truancy, inconsistent work behavior and traffic arrests. A Secret Service agent recently asked if I was familiar with a FBI report that almost half of the killers of law enforcement officers met the criteria for antisocial personality. I replied that I had not seen the report but that the finding did not seem surprising or noteworthy to me. My comment was based on the assumption that the report had used antisocial personality as a synonym for antisocial personality disorder ASPD , a category listed in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders DSM-IV and applicable to the majority of criminals.

Antisocial personality disorder ASPD , also known as dyssocial personality disorder, is a mental illness that is characterized by a reckless disregard for social norms, impulsive behaviour, an inability to experience guilt, and a low tolerance for frustration. Individuals with ASPD exhibit an inflated sense of self-worth and possess a superficial charm, traits that often aid their attempts to exploit and violate the rights of others. Although the causes of ASPD are highly disputed, research has found that antisocial behaviour is linked to abnormalities in the chemistry and anatomy of the human brain. Low levels of the neurotransmitter serotonin and maldevelopment of limbic and septal brain regions are believed to affect judgement, planning, and impulse control in ASPD sufferers. Furthermore, environmental factors, including low socio-economic status, low education levels, and familial lifestyle, contribute to the onset of ASPD. Criminal behaviour is frequently associated with ASPD. Hence, investigating the biological mechanisms underlying ASPD may improve our understanding of the criminal mentality, reducing the prevalence of crime in society.
