Human deficiencies are qualities of the mental and physical organization that are considered undesirable, can reflect the personal, behavioral and physical manifestations of a person, include his actions and taste. Those. relate to absolutely any sphere of human manifestation, but not satisfying either directly the person, or someone who assesses the personality. Advantages and disadvantages of a person have a subjective radical, as the main one for definition. The impossibility of an unambiguous and static separation of qualities into good and bad causes confusion in the distinction and classification of human manifestations as disadvantages or advantages. Also, in different situations that bring different semantic context, the same actions have different interpretations, as a manifestation of lack or dignity (for example, quick response, without taking into account the smallest details, in family life - lack, while in a military danger situation this quality plays the primary role role and is considered a virtue).
Mentioning a deficiency implies a context of a small amount or lack of something, although this is also true of character (lack of patience or honesty).
