Meme


A meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme. A meme acts as a unit for carrying cultural ideas, symbols, or practices, that can be transmitted from one mind to another through writing, speech, gestures, rituals, or other imitable phenomena with a mimicked theme. Supporters of the concept regard memes as cultural analogues to genes in that they self-replicate, mutate, and respond to selective pressures. In popular language, a meme may refer to an Internet meme, typically an image, that is remixed, copied, and circulated in a shared cultural experience online.
Proponents theorize that memes are a viral phenomenon that may evolve by natural selection in a manner analogous to that of biological evolution. Memes do this through processes analogous to those of variation, mutation, competition, and inheritance, each of which influences a meme's reproductive success. Memes spread through the behavior that they generate in their hosts. Memes that propagate less prolifically may become extinct, while others may survive, spread, and mutate. Memes that replicate most effectively enjoy more success, and some may replicate effectively even when they prove to be detrimental to the welfare of their hosts.
A field of study called memetics arose in the 1990s to explore the concepts and transmission of memes in terms of an evolutionary model. Criticism from a variety of fronts has challenged the notion that academic study can examine memes empirically. However, developments in neuroimaging may make empirical study possible. Some commentators in the social sciences question the idea that one can meaningfully categorize culture in terms of discrete units, and are especially critical of the biological nature of the theory's underpinnings. Others have argued that this use of the term is the result of a misunderstanding of the original proposal.
The word meme itself is a neologism coined by Richard Dawkins, originating from his 1976 book The Selfish Gene. Dawkins's own position is somewhat ambiguous. He welcomed N. K. Humphrey's suggestion that "memes should be considered as living structures, not just metaphorically", and proposed to regard memes as "physically residing in the brain". Although Dawkins said his original intentions had been simpler, he approved Humphrey's opinion and he endorsed Susan Blackmore's 1999 project to give a scientific theory of memes, complete with predictions and empirical support.

Etymology

The term meme is a shortening of mimeme, which comes from Ancient Greek mīmēma, meaning 'imitated thing', itself from mimeisthai, from mimos.
The word was coined by British evolutionary biologist Richard Dawkins in The Selfish Gene as a concept for discussion of evolutionary principles in explaining the spread of ideas and cultural phenomena. Examples of memes given in Dawkins' book include melodies, catchphrases, fashion, and the technology of building arches.

Origins

Early formulations

Although Richard Dawkins invented the term meme and developed meme theory, he has not claimed that the idea was entirely novel, and there have been other expressions for similar ideas in the past.
For instance, the possibility that ideas were subject to the same pressures of evolution as were biological attributes was discussed in the time of Charles Darwin. T. H. Huxley claimed that "The struggle for existence holds as much in the intellectual as in the physical world. A theory is a species of thinking, and its right to exist is coextensive with its power of resisting extinction by its rivals." G. K. Chesterton observed the similarity between intellectual systems and living organisms, noting that a certain degree of complexity, rather than being a hindrance, is a necessity for continued survival.
In 1904, Richard Semon published Die Mneme. The term mneme was also used in Maurice Maeterlinck's The Life of the White Ant, with some parallels to Dawkins's concept. Kenneth Pike had, in 1954, coined the related terms emic and etic, generalizing the linguistic units of phoneme, morpheme, grapheme, lexeme, and tagmeme, distinguishing insider and outside views of communicative behavior.

Dawkins

The word meme originated with Richard Dawkins' 1976 book The Selfish Gene.
Dawkins cites as inspiration the work of geneticist L. L. Cavalli-Sforza, anthropologist F. T. Cloak, and ethologist J. M. Cullen. Dawkins wrote that evolution depended not on the particular chemical basis of genetics, but only on the existence of a self-replicating unit of transmission—in the case of biological evolution, the gene. For Dawkins, the meme exemplified another self-replicating unit with potential significance in explaining human behavior and cultural evolution.
File:Kilroy was here.gif|thumb|right|"Kilroy was here" was a graffito that became popular in the 1940s, and existed under various names in different countries, illustrating how a meme can be modified through replication. This is seen as one of the first widespread memes in the world.
Dawkins used the term to refer to any cultural entity that an observer might consider a replicator. He hypothesized that one could view many cultural entities as replicators, and pointed to melodies, fashions and learned skills as examples. Memes generally replicate through exposure to humans, who have evolved as efficient copiers of information and behavior. Because humans do not always copy memes perfectly, and because they may refine, combine or otherwise modify them with other memes to create new memes, they can change over time. Dawkins likened the process by which memes survive and change through the evolution of culture to the natural selection of genes in biological evolution.
Dawkins noted that in a society with culture a person need not have biological descendants to remain influential in the actions of individuals thousands of years after their death:
But if you contribute to the world's culture, if you have a good idea...it may live on, intact, long after your genes have dissolved in the common pool. Socrates may or may not have a gene or two alive in the world today, as G.C. Williams has remarked, but who cares? The meme-complexes of Socrates, Leonardo, Copernicus and Marconi are still going strong.

In that context, Dawkins defined the meme as a unit of cultural transmission, or a unit of imitation and replication, but later definitions would vary. The lack of a consistent, rigorous, and precise understanding of what typically makes up one unit of cultural transmission remains a problem in debates about memetics. In contrast, the concept of genetics gained concrete evidence with the discovery of the biological functions of DNA. Meme transmission requires a physical medium, such as photons, sound waves, touch, taste, or smell because memes can be transmitted only through the senses.

After Dawkins: Role of physical media

Initially, Dawkins did not seriously give context to the material of memetics. He considered a meme to be an idea, and thus a mental concept. However, from Dawkins' initial conception, it is how a medium might function in relation to the meme which has garnered the most attention. For example, David Hull suggested that while memes might exist as Dawkins conceives of them, he finds it important to suggest that instead of determining them as idea "replicators" one might notice that the medium itself has an influence in the meme's evolutionary outcomes. Thus, he refers to the medium as an "interactor" to avoid this determinism. Alternatively, Daniel Dennett suggests that the medium and the idea are not distinct in that memes only exist because of their medium. Dennett argued this in order to remain consistent with his denial of qualia and the notion of materially deterministic evolution which was consistent with Dawkins' account. A particularly more divergent theory is that of Limor Shifman, a communication and media scholar of "Internet memetics". She argues that any memetic argument which claims the distinction between the meme and the meme-vehicle are empirically observable is mistaken from the offset. Shifman claims to be following a similar theoretical direction as Susan Blackmore; however, her attention to the media surrounding Internet culture has enabled Internet memetic research to depart in empirical interests from previous memetic goals. Regardless of Internet Memetic's divergence in theoretical interests, it plays a significant role in theorizing and empirically investigating the connection between cultural ideologies, behaviors, and their mediation processes.

Memetic lifecycle: transmission, retention

Memes, analogously to genes, vary in their aptitude to replicate; successful memes remain and spread, whereas unfit ones stall and are forgotten. Thus, memes that prove more effective at replicating and surviving are selected in the meme pool.
Memes first need retention. The longer a meme stays in its hosts, the higher its chances of propagation are. When a host uses a meme, the meme's life is extended. The reuse of the neural space hosting a certain meme's copy to host different memes is the greatest threat to that meme's copy. A meme that increases the longevity of its hosts will generally survive longer. On the contrary, a meme that shortens the longevity of its hosts will tend to disappear faster. However, as hosts are mortal, retention is not sufficient to perpetuate a meme in the long term; memes also need transmission.
Life-forms can transmit information both vertically and horizontally.
Memes can replicate vertically or horizontally within a single biological generation. They may also lie dormant for long periods of time.
Memes reproduce by copying from a nervous system to another one, either by communication or imitation. Imitation often involves the copying of an observed behavior of another individual. Communication may be direct or indirect, where memes transmit from one individual to another through a copy recorded in an inanimate source, such as a book or a musical score. Adam McNamara has suggested that memes can be thereby classified as either internal or external memes.
Some commentators have likened the transmission of memes to the spread of contagions. Social contagions such as fads, hysteria, copycat crime, and copycat suicide exemplify memes seen as the contagious imitation of ideas. Observers distinguish the contagious imitation of memes from instinctively contagious phenomena such as yawning and laughing, which they consider innate behaviors.
Aaron Lynch described seven general patterns of meme transmission, or "thought contagion":
  1. Quantity of parenthood: an idea that influences the number of children one has. Children respond particularly receptively to the ideas of their parents, and thus ideas that directly or indirectly encourage a higher birth rate will replicate themselves at a higher rate than those that discourage higher birth rates.
  2. Efficiency of parenthood: an idea that increases the proportion of children who will adopt ideas of their parents. Cultural separatism exemplifies one practice in which one can expect a higher rate of meme-replication—because the meme for separation creates a barrier from exposure to competing ideas.
  3. Proselytic: ideas generally passed to others beyond one's own children. Ideas that encourage the proselytism of a meme, as seen in many religious or political movements, can replicate memes horizontally through a given generation, spreading more rapidly than parent-to-child meme-transmissions do.
  4. Preservational: ideas that influence those that hold them to continue to hold them for a long time. Ideas that encourage longevity in their hosts, or leave their hosts particularly resistant to abandoning or replacing these ideas, enhance the preservability of memes and afford protection from the competition or proselytism of other memes.
  5. Adversative: ideas that influence those that hold them to attack or sabotage competing ideas and/or those that hold them. Adversative replication can give an advantage in meme transmission when the meme itself encourages aggression against other memes.
  6. Cognitive: ideas perceived as cogent by most in the population who encounter them. Cognitively transmitted memes depend heavily on a cluster of other ideas and cognitive traits already widely held in the population, and thus usually spread more passively than other forms of meme transmission. Memes spread in cognitive transmission do not count as self-replicating.
  7. Motivational: ideas that people adopt because they perceive some self-interest in adopting them. Strictly speaking, motivationally transmitted memes do not self-propagate, but this mode of transmission often occurs in association with memes self-replicated in the efficiency parental, proselytic and preservational modes.
