Nonetheless, there are some general similarities as well as differences between these two personality types. Both types of personality have a pervasive pattern of disregard for the safety and rights of others. Deceit and manipulation are central features to both types of personality. Contrary to popular belief, a psychopath or sociopath is not necessarily violent.
The common features of a psychopath and sociopath lie in their shared diagnosis — antisocial personality disorder. The DSM-51 defines antisocial personality as someone have 3 or more of the following traits:
- Regularly breaks or flouts the law
- Constantly lies and deceives others
- Is impulsive and doesn’t plan ahead
- Can be prone to fighting and aggressiveness
- Has little regard for the safety of others
- Irresponsible, can’t meet financial obligations
- Doesn’t feel remorse or guilt
In both cases, some signs or symptoms are nearly always present before age 15. By the time a person is an adult, they are well on their way to becoming a psychopath or sociopath.
