definitions of abnormality

• Definitions of Abnormality is how defining a person or behavior as ‘abnormal’ implies something undesirable and requires change psychologists use various methods for distinguishing normal from abnormal
• The definition of abnormality must be objective so it must not depend on anyone's opinion or POV and it should produce the same result to whoever applies it. It must not be under or over-inclusive
• statistical infrequency

  Under this definition, a person’s trait, thinking or behavior is classified as abnormal if it is rare or statistically unusual.
• one strength of the statistical infrequency is how its still used in the real world today. Its used in clinical practice to diagnose disorders etc
• a limitation is that some infrequent characteristics can be positive so therefore it statistical infrequency can be used for diagnosis but never sufficient as the sole basis for defining abnormality
