A polygraph, popularly referred to as a lie detector, measures and records several physiological indices such as blood pressure, pulse, respiration, and skin conductivity while the subject is asked and answers a series of questions. The belief underpinning the use of the polygraph is that deceptive answers will produce physiological responses that can be differentiated from those associated with non-deceptive answers; the polygraph is one of several devices used for lie detection.
The polygraph was invented in 1921 by John Augustus Larson, a medical student at the University of California at Berkeley and a police officer of the Berkeley Police Department in Berkeley, California. The polygraph was on the Encyclopædia Britannica 2003 list of greatest inventions, described as inventions that "have had profound effects on human life for better or worse."
The efficacy of polygraphs is debated in the scientific community. In 2001, a significant fraction of the scientific community considered polygraphy to be pseudoscience. In 2002, a review by the National Academies of Science found that in populations untrained in countermeasures, polygraph testing can discriminate lying from truth telling at rates above chance, though below perfection. These results apply only to specific events and not to screening where it is assumed that polygraph would work less well. Effectiveness may also be worsened by countermeasures.

Dolly Rebecca Parton Dean (born January 19, 1946) is an American singer-songwriter, actress, author, businesswoman, and humanitarian, known primarily for her work in country music. Her career began as a child performer on the Cas Walker radio show, then recording a few singles from the age of 13. Relocating to Nashville at age 18 in 1964, her first commercial successes were as a songwriter (her songs during this period were covered by numerous artists, including Bill Phillips and Kitty Wells). She rose to prominence in 1967 as a featured performer on singer Porter Wagoner's weekly syndicated TV program; their first duet single, a cover of Tom Paxton's "The Last Thing on My Mind", was a top-ten hit on the country singles chart and led to several successful albums before they ended their partnership in 1974. Moving towards mainstream pop music, her 1977 single "Here You Come Again" was a success on both the country and pop charts. A string of pop-country hits followed into the mid-1980s, the most successful being her 1980 hit "9 to 5" (from the film of the same name) and her 1983 duet with Kenny Rogers "Islands in the Stream", both of which topped the U.S. pop and country singles charts. A pair of albums recorded with Linda Ronstadt and Emmylou Harris were among her later successes. In the late 1990s, she returned to classic country/bluegrass with a series of acclaimed recordings. Non-musical ventures include Dollywood, a theme park in Pigeon Forge in the Smoky Mountains of Tennessee, and her efforts on behalf of childhood literacy, particularly her Imagination Library, as well as Dolly Parton's Dixie Stampede and Pirates Voyage Dinner & Show.
