Which of the following statements is true regarding psychopathy?

A) People with psychopathy have never been able to achieve professional success.
B) When they need to, people with psychopathy can be gracious and cheerful.
C) Almost all people with psychopathy are unable to maintain an outward appearance of normality.
D) People with psychopathy often lack intellectual abilities and can't execute neurocognitive functions.

While it is true that psychopathy is a personality disorder characterized by traits such as lack of empathy, manipulation, and impulsivity, it is not true that all people with psychopathy are unsuccessful or unable to maintain an outward appearance of normality. In fact, some studies have found that individuals with psychopathy can be charming and able to manipulate others to achieve their goals. However, this does not mean that their behavior is not harmful, and psychopathy is still associated with increased risk for criminal behavior and other negative outcomes.
