statistical infrequency

• Point: One strength of statistical infrequency is its usefulness.

  Evidence: Statistical infrequency is widely used in clinical practice for diagnosis and severity assessment, such as in intellectual disability disorder and the Beck Depression Inventory (BDI).

  Explain: This criterion aids in identifying conditions based on their statistical rarity, such as IDD for bottom 2% IQ and top 5% score on BDI to indicate severe depression.

  Link: Therefore, statistical infrequency serves as a valuable tool in clinical settings for identifying potential abnormalities.
• Point: One limitation of statistical infrequency is that infrequent characteristics can be positive as well as negative.

  Evidence: While statistical infrequency identifies rare traits, it fails to differentiate between positive and negative deviations. 

  Explain: For instance, high IQs are rare but considered positive, unlike low IQs.

  Link: Hence, although useful, statistical infrequency should be supplemented with other criteria to comprehensively define abnormality.
