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.

I, Q

I, Q is a 2000 Star Trek novel by John de Lancie and Peter David, set in the Star Trek: The Next Generation fictional universe. Like all Star Trek novels, it is not considered canon. The novel depicts Q joining forces with Captain Jean-Luc Picard and Lieutenant Commander Data to save his wife and child and avert the end of the universe. This is the first novel to explore Q's parenthood. He became a father in the Star Trek: Voyager episode The Q and the Grey.

Plot summary

The novel opens with a mysterious Lady, who, having grown bored with contemplating the Universe, has decided to bring it to an end. She walks to the beach of the island where she lives alone, and summons a storm. As the storm builds up, a bottle washes up to the shore. The Lady picks up the bottle, takes out a manuscript it contains, and begins to read as the storm stands by and waits for her.

Q is deep-sea fishing (literally standing at the bottom of an ocean) with his wife Q and son q, when the ocean begins draining into a giant whirlpool. Q powerlessly watches as his wife and son are taken in, and is only barely able to escape. He arrives in the Holodeck of the Enterprise, where Picard and Data's fishing simulation had been disturbed by the same disaster.
