Intelligence quotient

An intelligence quotient (IQ) is a score derived from one of several standardized tests designed to assess human intelligence. The abbreviation "IQ" was coined by the psychologist William Stern for the German term Intelligenzquotient, his term for a scoring method for intelligence tests he advocated in a 1912 book. When current IQ tests are developed, the median raw score of the norming sample is defined as IQ 100 and scores each standard deviation (SD) up or down are defined as 15 IQ points greater or less, although this was not always so historically. By this definition, approximately two-thirds of the population scores between IQ 85 and IQ 115. About 5 percent of the population scores above 125, and 5 percent below 75.

IQ scores have been shown to be associated with such factors as morbidity and mortality, parental social status, and, to a substantial degree, biological parental IQ. While the heritability of IQ has been investigated for nearly a century, there is still debate about the significance of heritability estimates and the mechanisms of inheritance.

Common sense

Common sense is a basic ability to perceive, understand, and judge things, which is shared by ("common to") nearly all people and can reasonably be expected of nearly all people without any need for debate.

The everyday understanding of what common sense is derived from philosophical discussion, involving several European languages. Related terms in other languages include Latin sensus communis, Greek κοινὴ αἲσθησις (koinē aísthēsis), and French bon sens, but these are not straightforward translations in all contexts. Similarly in English, there are different shades of meaning, implying more or less education and wisdom: "good sense" is sometimes seen as equivalent to "common sense", and sometimes not.

"Common sense" has at least two specifically philosophical meanings. One is a capability of the animal soul (Greek psukhē) proposed by Aristotle, which enables different individual senses to collectively perceive the characteristics of physical things such as movement and size, which all physical things have in different combinations, allowing people and other animals to distinguish and identify physical things. This common sense is distinct from basic sensory perception and from human rational thinking, but cooperates with both. The second special use of the term is Roman-influenced and is used for the natural human sensitivity for other humans and the community. Just like the everyday meaning, both of these refer to a type of basic awareness and ability to judge which most people are expected to share naturally, even if they can not explain why.

Crime fiction

Crime fiction is the literary genre that fictionalises crimes, their detection, criminals, and their motives. It is usually distinguished from mainstream fiction and other genres such as historical fiction or science fiction, but the boundaries are indistinct. Crime fiction has multiple sub-genres, including detective fiction (such as the whodunit), courtroom drama, hard-boiled fiction and legal thrillers. Suspense and mystery are key elements that are nearly ubiquitous to the genre.

In Italy people commonly call a story about detectives or crimes giallo (English: yellow), because books of crime fiction have usually had a yellow cover since the 1930s.

History of crime fiction

The earliest known crime fiction is Thomas Skinner Sturr's anonymous Richmond, or stories in the life of a Bow Street officer (1827); the earliest full-length novel in the genre is The Rector of Veilbye by the Danish author Steen Steensen Blicher, published in 1829. Better known are the earlier dark works of Edgar Allan Poe (e.g., "The Murders in the Rue Morgue" (1841), "The Mystery of Marie Roget" (1842), and "The Purloined Letter" (1844)). Wilkie Collins' epistolary novel The Woman in White was published in 1860, while The Moonstone (1868) is often thought to be his masterpiece. French author Émile Gaboriau's Monsieur Lecoq (1868) laid the groundwork for the methodical, scientifically minded detective. The evolution of locked room mysteries was one of the landmarks in the history of crime fiction. The Sherlock Holmes mysteries of Arthur Conan Doyle are said to have been singularly responsible for the huge popularity in this genre. A precursor was Paul Féval, whose series Les Habits Noirs (1862–67) features Scotland Yard detectives and criminal conspiracies. The best-selling crime novel of the nineteenth century was Fergus Hume's The Mystery of a Hansom Cab (1886), set in Melbourne, Australia.

Question

A question is a linguistic expression used to make a request for information, or the request made using such an expression. The information requested should be provided in the form of an answer.

Questions have developed a range of uses that go beyond the simple eliciting of information from another party. Rhetorical questions, for example, are used to make a point, and are not expected to be answered. Many languages have special grammatical forms for questions (for example, in the English sentence "Are you happy?", the inversion of the subject you and the verb are shows it to be a question rather than a statement). However questions can also be asked without using these interrogative grammatical structures – for example one may use an imperative, as in "Tell me your name".

Uses

The principal use of questions is to elicit information from the person being addressed, by indicating, more or less precisely, the information which the speaker (or writer) desires. However questions can also be used for a number of other purposes. Questions may be asked for the purpose of testing someone's knowledge, as in a quiz or examination. Raising a question may guide the questioner along an avenue of research (see Socratic method).
