Memetics is a controversial theory of mental content based on an analogy with Darwinian evolution, originating from the popularization of Richard Dawkins' 1976 book The Selfish Gene. It purports to be an approach to evolutionary models of cultural information transfer.

The meme, analogous to a gene, was conceived as a "unit of culture" (an idea, belief, pattern of behaviour, etc.) which is "hosted" in one or more individual minds, and which can reproduce itself, thereby jumping from mind to mind. Thus what would otherwise be regarded as one individual influencing another to adopt a belief is seen—when adopting the intentional stance—as an idea-replicator reproducing itself in a new host. As with genetics, particularly under a Dawkinsian interpretation, a meme's success may be due to its contribution to the effectiveness of its host.

Memetics is also notable for sidestepping the traditional concern with the truth of ideas and beliefs. Instead, it is interested in their success.

The Usenet newsgroup alt.memetics started in 1993 with peak posting years in the mid to late 1990s. The Journal of Memetics was published electronically from 1997 to 2005.

Susan Jane Blackmore (born 29 July 1951) is an English freelance writer, lecturer, and broadcaster on psychology and the paranormal, perhaps best known for her book The Meme Machine.

In 1973, Susan Blackmore graduated from St Hilda's College, Oxford, with a BA (Hons) degree in psychology and physiology. She went on to do postgraduate study in environmental psychology at the University of Surrey, achieving an MSc degree in 1974. In 1980, she got her PhD degree in parapsychology from the same university, her thesis being entitled "Extrasensory Perception as a Cognitive Process." After some period of time spent in research on parapsychology and the paranormal, her attitude towards the field moved from belief to scepticism. In 1987, Blackmore wrote that she had believed herself to have undergone an out-of-body experience shortly after she began running the Oxford University Society for Psychical Research (OUSPR):

Within a few weeks I had not only learned a lot about the occult and the paranormal, but I had an experience that was to have a lasting effect on me—an out-of-body experience (OBE). It happened while I was wide awake, sitting talking to friends. It lasted about three hours and included everything from a typical "astral projection," complete with silver cord and duplicate body, to free-floating flying, and finally to a mystical experience. It was clear to me that the doctrine of astral projection, with its astral bodies floating about on astral planes, was intellectually unsatisfactory. But to dismiss the experience as "just imagination" would be impossible without being dishonest about how it had felt at the time. It had felt quite real. Everything looked clear and vivid, and I was able to think and speak quite clearly.

Clinton Richard Dawkins, FRS, FRSL (born 26 March 1941), known as Richard Dawkins, is a British ethologist, evolutionary biologist and author. He is an emeritus fellow of New College, Oxford, and was the University of Oxford's Professor for Public Understanding of Science from 1995 until 2008.

Dawkins came to prominence with his 1976 book The Selfish Gene, which popularised the gene-centered view of evolution and introduced the term meme. In 1982 he introduced an influential concept into evolutionary biology, presented in his book The Extended Phenotype, that the phenotypic effects of a gene are not necessarily limited to an organism's body, but can stretch far into the environment, including the bodies of other organisms.

Dawkins is an atheist, a vice president of the British Humanist Association, and a supporter of the Brights movement. He is well known for his criticism of creationism and intelligent design. In his 1986 book The Blind Watchmaker, he argued against the watchmaker analogy, an argument for the existence of a supernatural creator based upon the complexity of living organisms. Instead, he described evolutionary processes as analogous to a blind watchmaker. He has since written several popular science books, and makes regular television and radio appearances, predominantly discussing these topics. In his 2006 book The God Delusion, Dawkins contends that a supernatural creator almost certainly does not exist and that religious faith is a delusion—"a fixed false belief." As of January 2010 the English-language version has sold more than two million copies and had been translated into 31 languages.
