Under Gordon Allport's 'Trait Theory of Personality', after conducting a deep psychological and analytical study of the classification of traits—Cardinal Traits, Central Traits, and Secondary Traits—what is the specific ontological and behavioral characteristic of a 'Cardinal Traits' that makes it completely distinct and unique from the other two types of traits?

Gordon Allport categorized personality traits into three categories in his trait theory. 'Cardinal Traits' are so dominant and pervasive that almost every act and decision of a person's life is influenced by them. They are so rare that they are not found in most people, but are clearly visible in historical or extraordinary personalities such as Mahatma Gandhi or Hitler. For a detailed study of this theory, you can refer to the Wikipedia reference.
