What did Jayne Mansfield claim her IQ to be?

Jayne Mansfield (born Vera Jayne Palmer; April 19, 1933 – June 29, 1967) was an American film, theater, and television actress. She was also a nightclub entertainer and a singer, and one of the early Playboy Playmates. She was a major Hollywood sex symbol during the 1950s and early 1960s while under contract at 20th Century Fox. She was also known for her well-publicized personal life and publicity stunts, such as "wardrobe malfunctions".

Frequent references have been made to Mansfield's very high IQ, which she claimed was 163. In addition to English, she spoke four other languages. She learned French, Spanish, and German in high school, and in 1963 she studied Italian. Reputed to be Hollywood's "smartest dumb blonde", she later complained that the public did not care about her brains saying, "They're more interested in 40–21–35."

An intelligence quotient (IQ) is a total score derived from 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 at University of Breslau he advocated in a 1912 book. Historically, IQ is a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months. The resulting fraction is multiplied by 100 to obtain the IQ score.
