Which of the following statements about psychopathy and crime is supported by the material?

• A. Approximately 5%
• B. 90%
• C. Approximately 40% of convicted criminals are psychopathic or have psychopathic tendencies
• D. 100%

Answer: (C)

Psychopathy shows up more often in prison populations than in the general public, but it is not something that affects everyone. In criminology research, a substantial minority of convicted criminals score high on psychopathic traits or meet criteria for psychopathy. A figure you’ll see echoed across studies is about four in ten, or roughly 40%, of incarcerated individuals showing psychopathic tendencies. This reflects how these traits—callousness, lack of empathy, impulsivity, and manipulativeness—are linked with patterns of offending and higher risk of reoffending, which helps explain why such individuals are disproportionately represented in criminal samples.

Think of it as a significant minority rather than a majority or a universal trait. That’s why the estimate around 40% is the best-supported statement: it acknowledges the strong association without claiming that every offender is a psychopath. The other options—only a tiny fraction, an overwhelming majority, or everyone—don’t align with the pattern seen in the data, where prevalence varies by sample and measurement method but hovers around that substantial minority level.
