A 70-year-old's IQ varies, but averages can be around 119 for ages 70-74, showing a peak in crystallized intelligence (knowledge/experience) even as fluid skills decline, with scores often staying stable or even increasing due to accumulated wisdom, though some sources show lower averages in older groups, highlighting different measurement aspects. The general IQ average is 100, but older adults often score higher on tests measuring accumulated knowledge, a concept known as crystallized intelligence.
Varying IQ Scores Across Age Groups
As people age, especially into their later years, there is a noticeable decline in IQ scores. Notably, individuals aged 70 to 74 may score around 119, but by the time they reach 75 and older, the average IQ can drop to as low as 79.
Lady Gaga's IQ is widely rumored to be around 166, placing her in the "exceptionally gifted" or genius category, though this is an estimation often cited in celebrity lists, not a officially verified number from a public test. This high estimate is supported by her early academic achievements, like attending a summer program for the top 1% of students, and her demonstrated creative and musical genius as a composer and performer, notes Us Weekly and Brainmanager.io.
A 72 IQ is considered Borderline Intellectual Functioning (BIF), falling just above the threshold for intellectual disability (usually around 70), placing it in the lower end of the spectrum (70-79) and indicating slower learning and potential needs for support in daily living, though it's not low enough for an official intellectual disability diagnosis by itself, notes Quora user. It's in the bottom few percentiles of the population, requiring more time to grasp complex concepts but not necessarily severe impairment.
The majority of researchers believe that IQ remains stable with age but that the components of a person's intelligence change. The changing components of intelligence can usually be described as fluid intelligence and crystallized intelligence. Fluid intelligence is the ability to reason and process information.
Her songwriting & business smarts suggest above-average intelligence, but real IQ needs a pro test. Taylor Swift's IQ is often cited online as 160, which would place her in the top 0.01% of the population, higher than 99.99% of people.
Nicole Kidman, whose shyness and stutter made her early years difficult, nevertheless showed an impressive aptitude for ballet and acting at a young age (and at one point had a reported IQ of 132).
IQ tests are not perfect, not should they be used to create a class-ist society ruled by high testers. Paris Hilton has a 129 IQ and Andy Warhol's was 86. But who contributed more to society?
Careers in the medical field, computer programing, university research positions, and engineering are among the ones with the highest requirements to be smart and have a high IQ.
Studies have shown that intelligence has a genetic component, but they have not conclusively identified any single genes that have major roles in differences in intelligence. It is likely that intelligence involves many genes that each make only a small contribution to a person's intelligence.
However, I know learners with measured IQ scores in the 40s who have learnt to read and write simple texts (though I'm not sure their IQ scores were accurate), and there's no reason to think that someone with an IQ of 60 or more can't learn to read and write at least at a basic level.
An estimated 89 percent of all people with retardation have I.Q.s in the 51-70 range. An I.Q. in the 60 to 70 range is approximately the scholastic equivalent to the third grade.
The term borderline intellectual functioning describes a group of people who function on the border between normal intellectual functioning and intellectual disability, between 1 and 2 standard deviations below the mean on the normal curve of the distribution of intelligence, roughly an IQ between 70 and 85.
Thus, for example, using the traditional formula of MA/CA × 100= IQ (where MA = mental age and CA = chronological age) then a child with intellectual disability with an IQ of 60 will be 10 years old when they attain the mental age, of 6, whereas their typically developing peer will be 6 years old.

While scientists have always argued that IQ is baked into our DNA at birth, new research finds that certain aspects of intelligence are influenced by working memory, a cognitive skill that can be exercised. These findings suggest IQ is not fixed — it can be improved if working memory can be improved.
Some mental skills are sharpest at different ages, with many not peaking until age 40 or later. Short-term memory is strongest at age 25, stays steady until 35, and then starts to decline. Emotional understanding peaks during middle age, while vocabulary and crystallized intelligence peak in the 60s and 70s.
Even if you have what is considered a low IQ, you may be smart in many other ways and have many other talents and abilities that aren't reflected on a single test. Other factors, such as hard work, resilience, perseverance, and overall attitude, are important pieces of the puzzle.
