psychopathology are disorders that are deviations from normality. Normality, and abnormality, can be characterized statistically. Related to the previous definition, statistical normality is usually defined it in terms of a normal distribution curve, with the so-called 'normal zone' commonly accounting for 95.45% of all the data. The remaining 4.55% will lie split outside of two standard deviations from the mean. Thus any variable case that lies outside of two deviations from the mean would be considered abnormal. However, the critical value of such statistical judgments may be subjectively altered to a less conservative estimate. It is in fact normal for a population to have a proportion of abnormals. The presence of abnormals is important because it is necessary to define what 'normal' is, as normality is a relative concept. So at a group, or macro, level of analysis, abnormalities are normal given a demographic survey; while at an individual level, abnormal individuals are seen as being deviant in some way that needs to be corrected. Statistical normality is important in determining demographic pathologies. When a variable rate, such as virus spread within a human population, exceeds its normal infection rate, then preventative or emergency measures can be introduced. However, it is often impractical to apply statistical normality to diagnose individuals. Symptom normality is the current, and assumed most effective, way to assess patient pathology. DSM Normality, as a relative concept, is intrinsically involved with contextual elements. As a result, clinical disorder classification has particular challenges in discretely diagnosing 'normal' constitutions from true disorders. The Diagnostic and Statistical Manual of Mental Disorders (DSM) is the psychiatric profession's official classification manual of mental disorders since its first published version (DSM-I) by the American Psychological Association in 1952. As the DSM evolved into its current version (DSM-V) in late 2013, there have been numerous conflicts in proposed classification between mental illness and normal mentality. In his book Saving Normal, Dr. Allen Frances, who chaired the task force for content in the DSM-IV and DSM-IV-TR, wrote a scathing indictment of the pressures incumbent on the definition of "normal" relative to psychological constructs and mental illness. Most of this difficulty stems from the DSM's ambiguity of natural contextual stressor reactions versus individual dysfunction. There are some key progressions along the DSM history that have attempted to integrate some aspects of normality into proper diagnosis classification. As a diagnostic manual for classification of abnormalities, all DSMs
