In science and history, consilience [kun-sil-ee-ehns] (also convergence of evidence or concordance of evidence) refers to the principle that evidence from independent, unrelated sources can ‘converge’ to strong conclusions. That is, when multiple sources of evidence are in agreement, the conclusion can be very strong even when none of the individual sources of evidence are very strong on their own. Most established scientific knowledge is supported by a convergence of evidence: if not, the evidence is comparatively weak, and there will not likely be a strong scientific consensus.
The principle is based on the unity of knowledge (a thesis in philosophy of science that says that all the sciences form a unified whole); measuring the same result by several different methods should lead to the same answer. For example, it should not matter whether one measures the distance between the Great Pyramids of Giza by laser rangefinding, by satellite imaging, or with a meter stick – in all three cases, the answer should be approximately the same. For the same reason, different dating methods in geochronology should concur, a result in chemistry should not contradict a result in geology, etc.

Consilience
Consilience
‘Consilience [kun-sil-ee-ehns]: The Unity of Knowledge’ is a 1998 book by biologist E. O. Wilson on the unification of scientific fields of inquiry and the potential unification of hard and soft sciences (humanities). Wilson uses the term to describe the synthesis of knowledge from different specialized fields of human endeavor.
He defines it as: ‘Literally a ‘jumping together’ of knowledge by the linking of facts and fact-based theory across disciplines to create a common groundwork of explanation.’ Examples include the unification of Darwin’s theory of evolution with genetics; the unification of forces in modern physics; Einstein’s work unifying Brownian motion with atomic theory; Rene Descartes’ unification of geometry and algebra; and Newton’s universal gravitation, which unified the laws of falling bodies with the laws of planetary motion.
Self-Serving Bias
A self-serving bias is attributing successes to internal factors and failures to external factors. This bias is a mechanism for individuals to protect or enhance their own self-esteem.
A student who attributes a good grade on an exam to his or her own intelligence and hours of studying but a poor grade to the professor’s poor teaching ability and unfair test questions is exhibiting the self-serving bias. Studies have shown that similar attributions are made in various situations, such as the workplace, interpersonal relationships, sports, and consumer decisions.

Mistakes Were Made (But Not by Me)
Mistakes Were Made (But Not by Me) is a non-fiction book by social psychologists Carol Tavris and Elliot Aronson, first published in 2007. It deals with cognitive dissonance (discomfort caused by holding conflicting ideas simultaneously), self-serving bias (attributing successes to internal factors and failures to external factors), and other cognitive biases (deviations in judgment), using these psychological theories to illustrate how the perpetrators of hurtful acts justify and rationalize their behavior.
It describes a positive feedback loop of action and self-deception by which slight differences between people’s attitudes become polarized. Topics covered include: the doomsday cult described in ‘When Prophecy Fails’; the MMR vaccine controversy and Andrew Wakefield; marriage; day care sex abuse hysteria and false memory syndrome, confabulation of autobiographical memory; George W. Bush and the Iraq War; Criminal interrogations, trials, and capital punishment; Mel Gibson; and Oprah Winfrey and her involvement in the James Frey controversy.
Common Sense
Common sense is ‘sound and prudent judgment based on a simple perception of the situation or facts.’ Thus, ‘common sense’ (in this view) equates to the knowledge and experience which most people already have, or which the person using the term believes that they do or should have. It is ‘the basic level of practical knowledge and judgment that we all need to help us live in a reasonable and safe way.’
However, identifying particular items of knowledge as ‘common sense’ is difficult. Philosophers may choose to avoid using the phrase when using precise language. Common sense remains a perennial topic in epistemology (the study of knowledge) and many philosophers make wide use of the concept or at least refer to it. Some related concepts include intuitions, pre-theoretic belief, ordinary language, the frame problem, foundational beliefs, good sense, endoxa, axioms, wisdom, folk wisdom, folklore, and public opinion.

Folk Psychology
Folk psychology can be described as the common understanding of mental processes (e.g. pain, pleasure, excitement, anxiety, etc.), grounded in the use of common linguistic terms as opposed to technical or scientific jargon. Folk psychology and analogy are invariably linked, with both concepts having evolved as a result of the relationship they have with each other. Once technical terms are stripped, the easiest way to describe something is through references to familiar items. In this way, the union between analogy and folk psychology was inevitable.
Traditionally, the study of folk psychology has focused on how everyday people—those without formal training in the various academic fields of science—go about attributing mental states. This domain has primarily been centered on intentional states reflective of an individual’s beliefs and desires; each described in terms of everyday language and concepts such as ‘beliefs,’ ‘desires,’ ‘fear,’ and ‘hope.’ As a result of this among other intrinsic factors, the domain’s scope, method, and contributions are consistently subjects of dispute in many scientific quarters.

Boundaries of the Mind
Boundaries of the mind refers to a personality trait concerning the degree of separateness (‘thickness’) or connection (‘thinness’) between mental functions and processes. Thin boundaries are associated with open-mindedness, sensitivity, vulnerability, creativity, and artistic ability.
People with thin boundaries may tend to confuse fantasy and reality and tend to have a fluid sense of identity, so that they tend to merge or lose themselves in their relations with others. People with thick boundaries differentiate clearly between reality and fantasy and between self and other, and tend to prefer well-defined social structures. The concept was developed by psychoanalyst Ernest Hartmann from his observations of the personality characteristics of frequent nightmare sufferers. The construct has been particularly studied in relation to dream recall and lucid dreaming.

Proxemics
Proxemics [prok-see-miks] is a subcategory of the study of nonverbal communication along with haptics (touch), kinesics (body movement), vocalics (paralanguage), and chronemics (structure of time). Proxemics can be defined as ‘the interrelated observations and theories of man’s use of space as a specialized elaboration of culture.’
Edward T. Hall, the cultural anthropologist who coined the term in 1963, emphasized the impact of proxemic behavior (the use of space) on interpersonal communication. Hall believed that the value in studying proxemics comes from its applicability in evaluating not only the way man interacts with others in his daily life, but also ‘the organization of space in his houses and buildings, and ultimately the layout of his towns.’

Intentional Stance
The intentional stance is a term coined by philosopher Daniel Dennett for the level of abstraction in which we view the behavior of a thing in terms of mental properties. It is part of a theory of mental content proposed by Dennett, which provides the underpinnings of his later works on free will, consciousness, folk psychology, and evolution.
‘Here is how it works: first you decide to treat the object whose behavior is to be predicted as a rational agent; then you figure out what beliefs that agent ought to have, given its place in the world and its purpose. Then you figure out what desires it ought to have, on the same considerations, and finally you predict that this rational agent will act to further its goals in the light of its beliefs. A little practical reasoning from the chosen set of beliefs and desires will in most instances yield a decision about what the agent ought to do; that is what you predict the agent will do.’

Animal Prostitution
Different studies show animal prostitution exists among species such as Adélie Penguins, chimpanzees, and crab-eating macaque. Penguins use stones for building their nests. A shortage of stones led female Adélie Penguins to trade sex for stones. The female penguins, even when in a committed relationship, will exchange sexual favors with strange males for the pebbles they need to build their nests. Prostitution is also observed among chimpanzees, who trade food for sex.
The first documented case of prostitution in animals was reported in 1998 by Fiona Hunter and Lloyd Davis, who had spent five years observing the mating behavior of penguins. The study was conducted as part of an Antarctica New Zealand program on the Ross Island, approximately 800 miles from the South Pole. The female penguins observed under the study were coupled with males. The females will go outside alone to collect pebbles, but the males did not suspect their female partners. According to the observations and analysis made by Hunter, the prostitute penguins targeted single males, because if instead they picked a male penguin with a partner, the male penguin’s current partner will come in conflict with the prostitute female.

Fermi Paradox
Fermi’s paradox asks why, given the age and size of the universe, we have not detected any other alien civilizations. Unless the Earth is very atypical, extraterrestrial life should be common. In an informal discussion in 1950, Italian American physicist Enrico Fermi questioned why, if a multitude of advanced extraterrestrial civilizations exists in the Milky Way galaxy, evidence such as spacecraft or probes is not seen.
Another common name for the phenomenon is silentium universi (‘the silence of the universe’). There have been attempts to resolve the paradox by locating evidence of extraterrestrial civilizations (e.g. SETI), along with proposals that such life could exist without human knowledge. Counterarguments suggest that intelligent extraterrestrial life does not exist or occurs so rarely or briefly that humans will never make contact with it.

Mosquito Control
Mosquito control manages the population of mosquitoes to reduce their damage to human health, economies, and enjoyment. Mosquito control is a vital public-health practice throughout the world and especially in the tropics because mosquitoes spread many diseases, such as malaria. Mosquito-control operations are targeted against three different problems:
Nuisance mosquitoes (bother people around homes or in parks and recreational areas); Economically important mosquitoes (reduce real estate values, adversely affect tourism and related business interests, or negatively impact livestock or poultry production); and Public health (focusing on mosquitoes as vectors, or transmitters, of infectious disease).
