Marilyn vos Savant - wikipedia Marilyn vos Savant US American magazine columnist, author and lecturer Marilyn vos Savant Savant at age 41. ( 1946 - 08 - 11 ) August 11, 1946 ( age 71 ) St. Louis, Missouri, U.S. Occupation Author, columnist Nationality American Spouse Robert Jarvik ( m. 1987 ) Website www.marilynvossavant.com Marilyn vos Savant ( / ˌvɒs səˈvɑːnt / ; born August 11, 1946 ) is an American magazine columnist, author, lecturer, and playwright. She was listed as having the highest recorded Intelligence quotient ( IQ ) in the Guinness Book of Records, a competitive category the publication has since retired. Since 1986, she has written `` Ask Marilyn '', a Parade magazine Sunday column where she solves puzzles and answers questions on various subjects. Among them was a discussion of the Monty Hall problem, which she answered correctly in 1990.

Savant says one should keep premarital surnames, with sons taking their fathers ' and daughters their mothers '. The word savant, meaning someone of learning, appears twice in her family : her grandmother 's name was Savant ; her grandfather 's, vos Savant. She is of Italian, Czechoslovak, German, and Austrian ancestry, being descended from physicist and philosopher Ernst Mach. Teenage Savant worked in her father 's general store and wrote for local newspapers using pseudonyms. She married at 16 and divorced ten years later. Her second marriage ended when she was 35. She went to Meramec Community College and studied philosophy at Washington University in St. Louis but quit two years later to help with a family investment business. Savant moved to New York City in the 1980s to pursue a career in writing. Prior to starting `` Ask Marilyn '', she wrote the Omni I.Q. Quiz Contest for Omni, which included IQ quizzes and expositions on intelligence and its testing. Savant married Robert Jarvik ( one developer of the Jarvik - 7 artificial heart ) on August 23, 1987, and was made Chief Financial Officer of Jarvik Heart, Inc. She has served on the board of directors of the National Council on Economic Education, on the advisory boards of the National Association for Gifted Children and the National Women 's History Museum, and as a fellow of the Committee for Skeptical Inquiry. Toastmasters International named her one of `` Five Outstanding Speakers of 1999 '', and in 2003 she was awarded an honorary Doctor of Letters from The College of New Jersey. Rise to Fame and IQ score Savant was listed in the Guinness Book of World Records under `` Highest IQ '' from 1986 to 1989 and entered the Guinness Book of World Records Hall of Fame in 1988. Guinness retired the `` Highest IQ '' category in 1990 after concluding IQ tests were too unreliable to designate a single record holder. The listing drew nationwide attention. Guinness cited vos Savant 's performance on two intelligence tests, the Stanford - Binet and the Mega Test. She took the 1937 Stanford - Binet, Second Revision test at age ten. She claims her first test was in September 1956 and measured her mental age at 22 years and 10 months, yielding a 228 score. This figure was listed in the Guinness Book of World Records ; it is also listed in her books ' biographical sections and was given by her in interviews. Alan S. Kaufman, a psychology professor and author of IQ tests, writes in IQ Testing 101 that `` Miss Savant was given an old version of the Stanford - Binet ( Terman & Merrill 1937 ), which did, indeed, use the antiquated formula of MA / CA × 100. But in the test manual 's norms, the Binet does not permit IQs to rise above 170 at any age, child or adult. And the authors of the old Binet stated : ' Beyond fifteen the mental ages are entirely artificial and are to be thought of as simply numerical scores. ' ( Terman & Merrill 1937 )... the psychologist who came up with an IQ of 228 committed an extrapolation of a misconception, thereby violating almost every rule imaginable concerning the meaning of IQs. '' Savant has commented on reports mentioning varying IQ scores she was said to have obtained. The second test reported by Guinness was Hoeflin 's Mega Test, taken in the mid-1980s. The Mega Test yields IQ standard scores obtained by multiplying the subject 's normalized z - score, or the rarity of the raw test score, by a constant standard deviation, and adding the product to 100, with Savant 's raw score reported by Hoeflin to be 46 out of a possible 48, with a 5.4 z - score, and a standard deviation of 16, arriving at a 186 IQ. The Mega Test has been criticized by professional psychologists as improperly designed and scored, `` nothing short of number pulverization ''. Savant sees IQ tests as measurements of a variety of mental abilities and thinks intelligence entails so many factors that `` attempts to measure it are useless ''. She has held memberships with the high - IQ societies Mensa International and the Mega Society. `` Ask Marilyn '' Following her listing in the 1986 Guinness Book of World Records, Parade ran a profile of her along with a selection of questions from Parade readers and her answers. Parade continued to get questions, so `` Ask Marilyn '' was made. She uses her column to answer questions on many chiefly academic subjects ; solve logical, mathematical or vocabulary puzzles posed by readers ; answer requests for advice with logic ; and give self - devised quizzes and puzzles. Aside from the weekly printed column, `` Ask Marilyn '' is a daily online column that adds to the printed version by resolving controversial answers, correcting mistakes, expanding answers, reposting previous answers, and solving additional questions. Three of her books ( Ask Marilyn, More Marilyn, and Of Course, I 'm for Monogamy ) are compilations of questions and answers from `` Ask Marilyn ''. The Power of Logical Thinking includes many questions and answers from the column. Famous columns The Monty Hall problem Main article : Monty Hall problem Savant was asked the following question in her September 9, 1990 column : `` Suppose you 're on a game show, and you 're given the choice of three doors. Behind one door is a car, behind the others, goats. You pick a door, say # 1, and the host, who knows what 's behind the doors, opens another door, say # 3, which has a goat. He says to you, `` Do you want to pick door # 2 ? '' Is it to your advantage to switch your choice of doors ? '' -- Craig F. Whitaker, Columbia, Maryland This question is called the Monty Hall problem due to its resembling scenarios on the game show Let 's Make a Deal ; its answer existed before it was used in `` Ask Marilyn ''. She said the selection should be switched to door # 2 because it has a ​ ⁄ chance of success, while door # 1 has just ​ ⁄. To summarize, ​ ⁄ of the time the opened door # 3 will indicate the location of the door with the car ( the door you had not picked and the one not opened by the host ). Only ​ ⁄ of the time will the opened door # 3 mislead you into changing from the winning door to a losing door. These probabilities assume you change your choice each time door # 3 is opened, and that the host always opens a door with a goat. This response provoked letters from thousands of readers, nearly all arguing doors # 1 and # 2 each have an equal chance of success. A follow - up column reaffirming her position served only to intensify the debate and soon became a feature article on the front page of The New York Times. Parade received around 10,000 letters from readers who thought that her workings were incorrect. Under the `` standard '' version of the problem, the host always opens a losing door and offers a switch. In the standard version, Savant 's answer is correct. However, the statement of the problem as posed in her column is ambiguous. The answer depends on what strategy the host is following. If the host operates under a strategy of only offering a switch if the initial guess is correct, it would clearly be disadvantageous to accept the offer. If the host merely selects a door at random, the question is likewise very different from the standard version. Savant addressed these issues by writing the following in Parade Magazine, `` the original answer defines certain conditions, the most significant of which is that the host always opens a losing door on purpose. Anything else is a different question. '' She expounded on her reasoning in a second follow - up and called on school teachers to show the problem to classes. In her final column on the problem, she gave the results of more than 1,000 school experiments. Most respondents now agree with her original solution, with half of the published letters declaring their authors had changed their minds. `` Two boys '' problem Main article : Boy or Girl paradox Like the Monty Hall problem, the `` two boys '' or `` second - sibling '' problem predates Ask Marilyn, but generated controversy in the column, first appearing there in 1991 -- 92 in the context of baby beagles : A shopkeeper says she has two new baby beagles to show you, but she does n't know whether they 're male, female, or a pair. You tell her that you want only a male, and she telephones the fellow who 's giving them a bath. `` Is at least one a male ? '' she asks him. `` Yes ! '' she informs you with a smile. What is the probability that the other one is a male ? -- Stephen I. Geller, Pasadena, California When Savant replied `` one out of three '', readers wrote the odds were 50 -- 50. In a follow - up, she defended her answer, saying that `` If we could shake a pair of puppies out of a cup the way we do dice, there are four ways they could land '', in three of which at least one is male, but in only one of which none are male. The confusion arises here because the bather is not asked if the puppy he is holding is a male, but rather if either is a male. If the puppies are labeled ( A and B ), each has a 50 % chance of being male independently. This independence is restricted when at least A or B is male. Now, if A is not male, B must be male, and vice versa. This restriction is introduced by the way the question is structured and is easily overlooked -- misleading people to the erroneous answer of 50 %. See Boy or Girl paradox for solution details. The problem re-emerged in 1996 -- 97 with two cases juxtaposed : Say that a woman and a man ( who are unrelated ) each have two children. We know that at least one of the woman 's children is a boy and that the man 's oldest child is a boy. Can you explain why the chances that the woman has two boys do not equal the chances that the man has two boys ? My algebra teacher insists that the probability is greater that the man has two boys, but I think the chances may be the same. What do you think ? Savant agreed with the teacher, saying the chances were only 1 out of 3 that the woman had two boys, but 1 out of 2 the man had two boys. Readers argued for 1 out of 2 in both cases, prompting follow - ups. Finally she began a survey, asking female readers with exactly two children, at least one of them male, to give the sex of both children. Of the 17,946 women who responded, 35.9 %, about 1 in 3, had two boys. Woman has young boy, older girl young girl, older boy 2 boys 2 girls Probability : 1 / 3 1 / 3 1 / 3 0 Man has young boy, older girl young girl, older boy 2 boys 2 girls Probability : 0 1 / 2 1 / 2 0 Errors in the column On January 22, 2012, Savant admitted a mistake in her column. In the original column, published on December 25, 2011, a reader asked : `` I manage a drug - testing program for an organization with 400 employees. Every three months, a random - number generator selects 100 names for testing. Afterward, these names go back into the selection pool. Obviously, the probability of an employee being chosen in one quarter is 25 percent. But what is the likelihood of being chosen over the course of a year ? '' Her response ( published on December 25, 2011 ) was : `` The probability remains 25 percent, despite the repeated testing. One might think that as the number of tests grows, the likelihood of being chosen increases, but as long as the size of the pool remains the same, so does the probability. Goes against your intuition, does n't it ? '' The correctness of the answer depends on how the question is asked. The probability of being chosen each time is 25 % but probability of being chosen at least once across the 4 events is higher. In this case, the correct answer is around 68 %, calculated as the complement of the probability of not being chosen in any of the four quarters : 1 -- ( 0.75 ). On May 5, 2013, Savant made an error in a combinatorics problem. The question was how many 4 - digit briefcase combinations contain a particular digit ( say 5, for example ). She said the answer was 4000, yet people showed the correct answer -- 3439 -- using various strategies. The incorrect answer of 4000 counted those combinations with more than one `` 5 '' multiple times ( twice for `` 1535 '', three times for `` 1555 '', for instance ). So, the correct answer is to take all possible combinations minus the combinations in which each digit is not a 5 to the n power, or 10,000 - 9 = 3439. On June 22, 2014, Savant made an error in a word problem. The question was : If two people could complete a project in six hours, how long would it take each of them to do identical projects on their own, given that one took four hours longer than the other ? Her answer was 10 hours and 14 hours, reasoning that if together it took them 6 hours to complete a project, then the total effort was 12 `` man hours ''. If they then each do a separate full project, the total effort needed would be 24 hours, so the answer ( 10 + 14 ) needed to add up to 24 with a difference of 4. However, this ignores the fact that the two people get different amounts of work done per hour : if they are working jointly on a project, they can maximize their combined productivity, but if they split the work in half, one person will finish sooner and ca n't fully contribute. This subtlety causes the problem to require solving a quadratic equation and thus to not have a rational solution. Instead, the answer is 4 + 40 ( displaystyle 4 + ( sqrt ( 40 ) ) ) ( approximately 10.32 ) and 8 + 40 ( displaystyle 8 + ( sqrt ( 40 ) ) ) ( approximately 14.32 ) hours. Savant later acknowledged the error. In her January 25, 2015, column Savant answered the question : `` Suppose you have a job offer with a choice of two annual salaries. One is $30,000 with a $1,000 raise every year. The other is $30,000 with a $300 raise every six months. Which option is best in the long run ? '' Savant claimed that the semi-annual $300 raises were better than the annual $1000 raise. Comments of a reader of her webpage pointed out that this was the same puzzle she presented many years ago, and that it was addressed by Cecil Adams ' column `` The Straight Dope '' in 1992. At that time Adams wrote, `` Her response is 100 percent correct. It 's just not necessarily the answer to the question she was asked. '' Fermat 's last theorem A few months after Andrew Wiles said he had proved Fermat 's Last Theorem, Savant published The World 's Most Famous Math Problem ( October 1993 ), which surveys the history of Fermat 's last theorem as well as other mathematical problems. Controversy came from its criticism of Wiles ' proof ; she was said to misunderstand mathematical induction, proof by contradiction, and imaginary numbers. Especially contested was her statement that Wiles ' proof should be rejected for its use of non-Euclidean geometry. She said that because `` the chain of proof is based in hyperbolic ( Lobachevskian ) geometry '', and because squaring the circle is seen as a `` famous impossibility '' despite being possible in hyperbolic geometry, then `` if we reject a hyperbolic method of squaring the circle, we should also reject a hyperbolic proof of Fermat 's last theorem. '' Specialists flagged discrepancies between the two cases, distinguishing the use of hyperbolic geometry as a `` tool '' for proving Fermat 's last theorem and from its use as a `` setting '' for squaring the circle : squaring the circle in hyperbolic geometry is a different problem from that of squaring it in Euclidean geometry. Savant was criticized for rejecting hyperbolic geometry as a satisfactory basis for Wiles ' proof, with critics pointing out that axiomatic set theory ( rather than Euclidean geometry ) is now the accepted foundation of mathematical proofs and that set theory is sufficiently robust to encompass both Euclidean and non-Euclidean geometry as well as geometry and adding numbers. Savant retracted the argument in a July 1995 addendum, saying she saw the theorem as `` an intellectual challenge -- ' to find a proof with Fermat 's tools. ' '' Publications 1985 -- Omni I.Q.

Lay summary ( 31 August 2013 ). And what is that makes Marilyn vos Savant so uniquely qualified to answer such questions ? There is only one reason : she is listed in the Guinness Book of World Records as having the highest IQ ever recorded. Never mind that this record is based on a non-standardized test put out by an obscure group known as Mega, supposedly the world 's most selective organization of geniuses. Ignore the fact that test scores at the extreme ends of any distribution are notoriously unreliable... None of this is meant to downplay her very real accomplishments ; by all accounts, vos Savant is a sensible and grounded woman, and she has won several awards for her work in the fields of education and communications. But her fame came, in the words of journalist Julie Baumgold, ' only because of the glory of that number. ' ( citing New York magazine 22 ( 1989 ) : 36 -- 42 ) Jump up ^ Kaufman, Alan S. ( 2009 ).
