Recently, Dr. Drew Curtis began to argue that pathological lying, as had been described historically, was not defined in the manner that contemporary mental health professionals define disorders. Specifically, he noted that disorders are based on four criteria: 1) atypicality (they are statistically infrequent or violate norms); 2) maladaptive (they impair functioning); 3) suffering (they cause emotional distress); and 4) danger (they create risks of harm or loss for self or others). These criteria are used to determine which patterns of behaviors, thoughts, and feelings are simply part of the natural variability of the human experience and which are pathological.
