General usage
Comparison is a natural activity, which even animals engage in when deciding, for example, which potential food to eat. Humans similarly have always engaged in comparison when hunting or foraging for food. This behavior carries over into activities like shopping for food, clothes, and other items, choosing which job to apply for or which job to take from multiple offers, or choosing which applicants to hire for employment. In commerce, people often engage in comparison shopping: attempting to get the best deal for a product by comparing the qualities of different available versions of that product and attempting to determine which one maximizes the return on the money spent. In the twenty-first century, as shopping has increasingly been done on the internet, comparison shopping websites have developed to aid shoppers in making such determinations. When consumers and others invest excessive thought into making comparisons, this can result in the problem of analysis paralysis. Humans also tend to compare themselves and their belongings with others, an activity also observed in some animals. Children begin developing the ability to compare themselves to others in elementary school. In adults, this can lead to unhappiness when a person compares things that they have to things they perceived as superior and unobtainable that others have. Some marketing relies on making such comparisons to entice people to purchase things so they compare more favorably with people who have these things. Social comparison theory, initially proposed by social psychologist Leon Festinger in 1954, centers on the belief that there is a drive within individuals to gain accurate self-evaluations. The theory explains how individuals evaluate their own opinions and abilities by comparing themselves to others to reduce uncertainty in these domains, and learn how to define the self. Following the initial theory, research began to focus on social comparison as a way of self-enhancement, introducing the concepts of downward and upward comparisons and expanding the motivations of social comparisons. Human language has evolved to suit this practice by facilitating Comparison (grammar), grammatical comparison, with comparative forms enabling a person to describe a thing as having more or less of a characteristic than another thing, or to describe a thing in a group as having the most or least of that characteristic relative to the group. The grammatical category associated with comparison of adjectives and adverbs is degree of comparison.Academics
Academically, comparison is used between things like economic and political systems. Political scientist and historian Benedict Anderson has cautioned against use of comparisons without considering the relevant framework of things being compared: Anderson notes as an example that "[i]n the jingoist years on the eve of the First World War, when Germans and Frenchmen were encouraged to hate each other, the great Austro-Marxist theoretician Otto Bauer enjoyed baiting both sides" by comparing their similarities, "saying that contemporary Parisians and Berliners had far more in common than either had with their respective medieval ancestors". Notably, the phrase "comparative studies" is generally used to refer to cross-cultural studies, within the fields of sociology and anthropology. Émile Durkheim, one of the founders of the field of sociology, said of this term that "comparative sociology is not a particular branch of sociology; it is sociology itself".Literature
The primary use of comparison in literature is with the simile, a figure of speech that directly compares two things. Similes are a form of metaphor that explicitly use connecting words (such as ''like, as, so, than,'' or various verbs such as ''resemble'') though these specific words are not always necessary. While similes are mainly used in forms of poetry that compare the inanimate and the living, there are also terms in which similes are used for humorous purposes of comparison. A number of literary works have commented negatively on the practice of comparison. For example, 15th century English poet John Lydgate wrote "[o]dyous of olde been comparsionis", which was reflected by many later writers, such as William Shakespeare, who included the line in ''Much Ado About Nothing'', "comparisons are odious". Miguel de Cervantes, in a passage in ''Don Quixote'', wrote, "[i]s it possible your pragmatical worship should not know that the comparisons made between wit and wit, courage and courage, beauty and beauty, birth and birth, are always odious and ill taken?"Miguel de Cervantes, ''Don Quixote'' (1605-15), Part II, Chapter I.See also
