The insanity defense has which of the following characteristics?

The insanity defense has which of the following characteristics?

• A. Legal medical definition
• B. Legal meaning but no medical definition
• C. A medical diagnosis
• D. Always results in acquittal

Answer: (B)

The key idea is that insanity is a legal concept, not a medical diagnosis. A clinician may diagnose a mental illness, but whether someone is legally insane is determined by the criminal law, not by medicine. The legal standard asks whether, at the time of the offense, the person could understand what they were doing or distinguish right from wrong (or could control their behavior under a specific rule), and the decision rests with the court or jury. Because it’s a legal criterion, the outcome is not guaranteed to be an acquittal; someone found legally insane may be confined or treated in a secure setting rather than released. This is why the correct description is that the insanity defense has a legal meaning but no sole medical definition.
