Not generally. IQ tests are age adjusted, basically to take account of youth and inexperience (under 18) or age and diminishing speed. The reason is that, as we get older, diminishing speed and spatial awareness are balanced by having more knowledge and experience to draw on to solve problems.
Researchers have previously shown that a person's IQ is highly influenced by genetic factors, and have even identified certain genes that play a role. They've also shown that performance in school has genetic factors.
Louis, Missouri in 1946 when Marilyn Vos Savant was 10 years old, in an adult level Stanford-Binet Test found out that her IQ is 228. Due to this record-breaking result, her name was recorded in the Guinness Book of World Records.
His estimated IQ scores range from 160 to 310 by different measures. He had an intense rivalry with Thomas Edison throughout his life, and many of his projects were funded by JPMorgan, who would later become his business partner.
Study finds brain structure and IQ can change during adolescence. A new study confirms what parents have long suspected: Adolescence can do a number on kids' brains. Researchers have found that IQ can rise or fall during the teen years and that the brain's structure reflects this uptick or decline.
"A highly intelligent person is one who is flexible in their thinking and can adapt to changes, they think before they speak or act, and they're able to effectively manage their emotions," Dr. Catherine Jackson, licensed clinical psychologist and board certified neurotherapist, tells Bustle.
Researchers found that the twins had "substantial differences" in their IQ. Tests revealed that the adopted twin had an IQ 16 points lower than her long-lost sister. This contradicts existing research that says identical twins usually have no more than 7 points difference in their IQ.
In addition to slowing down physically, most people lose points on intelligence tests as they enter their golden years. Now, new research suggests the loss of certain types of cognitive skills with age may stem from problems with basic sensory tasks, such as making quick judgments based on visual information.
As can be seen in the figure, Schaie's study indicates that the steep decline in intelligence usually only starts after age 60, with only perceptual speed declining seriously before 60. The study showed that verbal ability is stable for most people until age 70, after which the decline is still very slow!
Across 142 effect sizes from 42 data sets involving over 600,000 participants, we found consistent evidence for beneficial effects of education on cognitive abilities of approximately 1 to 5 IQ points for an additional year of education.
