Evolutionary psychology is a theoretical approach in psychology that examines cognition and behavior from a modern evolutionary perspective. It seeks to identify human psychological adaptations with regards to the ancestral problems they evolved to solve. In this framework, psychological traits and mechanisms are either functional products of natural and sexual selection or non-adaptive by-products of other adaptive traits.
Eugenics is a set of beliefs and practices that aim to improve the genetic quality of a human population. Historically, eugenicists have altered various human gene frequencies by inhibiting the fertility of people and groups they considered inferior, or promoting that of those considered superior.
Robert Mearns Yerkes was an American psychologist, ethologist, eugenicist and primatologist best known for his work in intelligence testing and in the field of comparative psychology.
Richard Lynn was a controversial English psychologist and self-described "scientific racist" who advocated for a genetic relationship between race and intelligence. He was the editor-in-chief of Mankind Quarterly, a white supremacist journal. He was lecturer in psychology at the University of Exeter and professor of psychology at the Economic and Social Research Institute, Dublin, and at the University of Ulster at Coleraine. Lynn was a professor emeritus of psychology at Ulster University, but had the title withdrawn by the university in 2018.
Evolutionary ethics is a field of inquiry that explores how evolutionary theory might bear on our understanding of ethics or morality. The range of issues investigated by evolutionary ethics is quite broad. Supporters of evolutionary ethics have argued that it has important implications in the fields of descriptive ethics, normative ethics, and metaethics.
In science and philosophy, a just-so story is an untestable narrative explanation for a cultural practice, a biological trait, or behavior of humans or other animals. The pejorative nature of the expression is an implicit criticism that reminds the listener of the fictional and unprovable nature of such an explanation. Such tales are common in folklore genres like mythology. A less pejorative term is a pourquoi story, which has been used to describe usually more mythological or otherwise traditional examples of this genre, aimed at children.
Geoffrey Franklin Miller is an American evolutionary psychologist, author, and associate professor of psychology at the University of New Mexico. He is known for his research on sexual selection in human evolution.
The wisdom of repugnance or appeal to disgust, also known informally as the yuck factor, is the belief that an intuitive negative response to some thing, idea, or practice should be interpreted as evidence for the intrinsically harmful or evil character of that thing. Furthermore, it refers to the notion that wisdom may manifest itself in feelings of disgust towards anything which lacks goodness or wisdom, though the feelings or the reasoning of such 'wisdom' may not be immediately explicable through reason.
Evolutionary psychology seeks to identify and understand human psychological traits that have evolved in much the same way as biological traits, through adaptation to environmental cues. Furthermore, it tends toward viewing the vast majority of psychological traits, certainly the most important ones, as the result of past adaptions, which has generated significant controversy and criticism from competing fields. These criticisms include disputes about the testability of evolutionary hypotheses, cognitive assumptions such as massive modularity, vagueness stemming from assumptions about the environment that leads to evolutionary adaptation, the importance of non-genetic and non-adaptive explanations, as well as political and ethical issues in the field itself.
Jonathan David Haidt is an American social psychologist and author. He is the Thomas Cooley Professor of Ethical Leadership at the New York University Stern School of Business. His main areas of study are the psychology of morality and moral emotions.
The concept of the evolution of morality refers to the emergence of human moral behavior over the course of human evolution. Morality can be defined as a system of ideas about right and wrong conduct. In everyday life, morality is typically associated with human behavior rather than animal behavior. The emerging fields of evolutionary biology, and in particular evolutionary psychology, have argued that, despite the complexity of human social behaviors, the precursors of human morality can be traced to the behaviors of many other social animals. Sociobiological explanations of human behavior remain controversial. Social scientists have traditionally viewed morality as a construct, and thus as culturally relative, although others such as Sam Harris argue that there is an objective science of morality.
Veneer theory is a term coined by Dutch primatologist Frans de Waal to label the Hobbesian view of human morality that he criticizes throughout his work. Although he criticizes this view in earlier works, the term in this form is introduced in his 2005 book Our Inner Ape, denoting a concept that he rejects, namely that human morality is "a cultural overlay, a thin veneer hiding an otherwise selfish and brutish nature". The idea of the veneer theory goes back to Thomas Henry Huxley and has more recently been advocated by biologists like George C. Williams.
Disgust is an emotional response of rejection or revulsion to something potentially contagious or something considered offensive, distasteful or unpleasant. In The Expression of the Emotions in Man and Animals, Charles Darwin wrote that disgust is a sensation that refers to something revolting. Disgust is experienced primarily in relation to the sense of taste, and secondarily to anything which causes a similar feeling by sense of smell, touch, or vision. Musically sensitive people may even be disgusted by the cacophony of inharmonious sounds. Research has continually proven a relationship between disgust and anxiety disorders such as arachnophobia, blood-injection-injury type phobias, and contamination fear related obsessive–compulsive disorder.
Sex at Dawn: The Prehistoric Origins of Modern Sexuality is a 2010 book about the evolution of human mating systems by Christopher Ryan and Cacilda Jethá. In opposition to what the authors see as the "standard narrative" of human sexual evolution, they contend that having multiple sexual partners was common and accepted in the environment of evolutionary adaptedness. The authors contend that mobile, self-contained groups of hunter-gatherers were the norm for humans before agriculture led to high population density. Before agriculture, according to the authors, sex was relatively promiscuous and paternity was not a concern. This dynamic is similar to the mating system of bonobos. According to the book, sexual interactions strengthened the bond of trust in the groups. Far from causing jealousy, social equilibrium and reciprocal obligation were strengthened by playful sexual interactions.
The history of evolutionary psychology began with Charles Darwin, who said that humans have social instincts that evolved by natural selection. Darwin's work inspired later psychologists such as William James and Sigmund Freud but for most of the 20th century psychologists focused more on behaviorism and proximate explanations for human behavior. E. O. Wilson's landmark 1975 book, Sociobiology, synthesized recent theoretical advances in evolutionary theory to explain social behavior in animals, including humans. Jerome Barkow, Leda Cosmides and John Tooby popularized the term "evolutionary psychology" in their 1992 book The Adapted Mind: Evolutionary Psychology and The Generation of Culture. Like sociobiology before it, evolutionary psychology has been embroiled in controversy, but evolutionary psychologists see their field as gaining increased acceptance overall.
Evolutionary aesthetics refers to evolutionary psychology theories in which the basic aesthetic preferences of Homo sapiens are argued to have evolved in order to enhance survival and reproductive success.
Evolutionary psychology has traditionally focused on individual-level behaviors, determined by species-typical psychological adaptations. Considerable work, though, has been done on how these adaptations shape and, ultimately govern, culture. Tooby and Cosmides (1989) argued that the mind consists of many domain-specific psychological adaptations, some of which may constrain what cultural material is learned or taught. As opposed to a domain-general cultural acquisition program, where an individual passively receives culturally-transmitted material from the group, Tooby and Cosmides (1989), among others, argue that: "the psyche evolved to generate adaptive rather than repetitive behavior, and hence critically analyzes the behavior of those surrounding it in highly structured and patterned ways, to be used as a rich source of information out of which to construct a 'private culture' or individually tailored adaptive system; in consequence, this system may or may not mirror the behavior of others in any given respect.".
Aurelio José Figueredo is an American evolutionary psychologist. He is a professor of psychology, Family Studies and Human Development at the University of Arizona, where he is also the director of the Ethology and Evolutionary Psychology Laboratory. He is also a member of the interdisciplinary Center for Insect Science at the University of Arizona. His major areas of research interest are the evolutionary psychology and behavioral development of life history strategy, cognition, sex, and violence in human and nonhuman animals, and the quantitative ethology and social development of insects, birds, and primates. He is known for his research on personality, such as a 1997 study in which he and James E. King developed the Chimpanzee Personality Questionnaire to measure the Big Five personality traits in chimpanzees.
Eugenic feminism was a current of the women's suffrage movement which overlapped with [[eugenics]]. Originally coined by the Lebanese-British physician and vocal eugenicist Caleb Saleeby, the term has since been applied to summarize views held by prominent feminists of Great Britain and the United States. Some early suffragettes in Canada, especially a group known as The Famous Five, also pushed for various eugenic policies.
