You can raise your IQ and overall cognitive ability through brain-stimulating activities like puzzles, learning new skills (especially languages), consistent reading, and regular exercise, alongside lifestyle factors like quality sleep, proper nutrition, and stress management (meditation), all of which enhance memory, focus, and problem-solving skills, though true IQ is partly genetic and stable.
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.
Research indicates that between 40% and 80% of the variance in IQ is attributed to genetics, highlighting a significant hereditary component. These findings emerge from studies of family pedigrees, twin studies, and recently, advances in molecular genetics.
Snoop Dogg has publicly stated he has an IQ of 147, a score that falls into the "highly gifted" or "genius" category, much to his own surprise given his self-described average school performance (straight Cs). While this self-reported score suggests exceptional intellect, IQ tests measure specific cognitive abilities, and success in life and business (like Snoop Dogg's multifaceted career as a rapper, entrepreneur, and media personality) reflects a broader range of intelligence and skills.
No, an IQ of 97 is not considered dumb; it falls squarely in the average range (90-109), indicating typical cognitive abilities, though some tests might place it slightly below the exact midpoint of 100. An IQ score of 97 means you performed better than 42% of people, and due to the test's margin of error, your score could be anywhere from the high 80s to the mid-100s, still within normal intelligence.
Tom Hanks as Forrest Gump: At an early age, Forrest is deemed to have a below-average IQ of 75. He has an endearing character and shows devotion to his loved ones and duties, character traits that bring him into many life-changing situations.
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.
We all know that Gaga is a creative genius, but it turns out she's an actual genius too with a widely-estimated IQ of 166, making her “exceptionally gifted” — and we don't disagree!
Kanye West (Ye) publicly claimed to have a 142 IQ in an April 2025 social media post, a score he stated meant he had a "genius intellect," though this remains an unverified, self-proclaimed figure not supported by official test results. While supporters praised the claim, many questioned its accuracy, and there's no official, independently verified IQ score for him, with intelligence being a multifaceted concept beyond a single number.
Madonna reportedly has a genius-level IQ of around 140, well above the average, with sources citing her intelligence and business acumen, often linking it to her ability to recognize patterns and disrupt culture. This high score is sometimes associated with her academic achievements, like receiving a scholarship to the University of Michigan, and her remarkable career longevity, making her a highly successful artist.
By contrast, intelligence tests at birth cannot predict intelligence at age 18 years. At 2 years of age, infant intelligence tests predict less than 5% of the variance of intelligence in late adolescence37,38.
Some signs that often appear in children include:
Although IQ can change for an individual, across a population it is well established that IQ is stable across the lifespan. This does NOT mean that our abilities do not change as we age. IQ (as the name indicates) is a QUOTIENT, i.e., your score is calculated relative to persons of your age.
Slowness learning to talk, or continued difficulties with speech and language skills after starting to talk. Difficulty with self-help and self-care skills (e.g., getting dressed, washing, and feeding themselves) Poor planning or problem-solving abilities. Behavioral and social problems.
To calculate IQ, take a person's mental age, divide it by chronological age, and then multiply that number by 100. For example, if a person has a mental age of 12 but is 10 years old, then you'd divide 12 by 10, and multiply that number by 100, which would result in an IQ of 120.
Borderline intellectual functioning, previously called borderline mental retardation (in the ICD-8), is a categorization of intelligence wherein a person has below average cognitive ability (generally an IQ of 70–85), but the deficit is not as severe as intellectual disability (below 70).
Ben Affleck's IQ is often cited as 154, placing him in the highly gifted range, though these figures for celebrities are estimates, with some sources also mentioning high intellect in relation to his work, such as co-writing Good Will Hunting with Matt Damon.
“I went to this doctor … My wife took me to do that because she said, 'Something about your personality doesn't feel like it's bipolar, I've seen bipolar before. ' And I've come to find that it's really a case of autism that I have,” West said. West said the diagnosis has helped him better understand himself.
Celebrity Genius 5 - James Woods
Emmy Award winner James Woods is an Oscar-nominee and superstar has a whopping IQ of 180. While in high school, Woods was in a UCLA linear algebra course.
Marilyn Monroe was more than a glamorous icon—she was deeply intelligent and loved literature and philosophy. She reportedly had an IQ of 168, even higher than einstein's estimated 160.
Lady Gaga lives with Fibromyalgia, a chronic pain condition causing widespread body pain, fatigue, "fibro fog," and mood issues, which she's openly shared to raise awareness, showing her struggles and treatment in her documentary Gaga: Five Foot Two and performances. She also deals with PTSD and previously suffered a significant leg injury, leading her to sometimes use mobility aids like canes, redefining disability representation for fans.
J. Robert Oppenheimer's IQ is unknown because he never took an official test, but estimates place him in the 130s-140s, suggesting very high intelligence, though some debate if IQ fully captures his genius, considering his vast knowledge in languages, literature, and physics, Britannica. While one source suggests 135 (99th percentile), others emphasize his polymath skills and leadership, noting IQ tests don't cover creativity, which was crucial to his success, IMDb.
A weighted average has been calculated at 0.75, with about an absolute average difference of 8.0 IQ points. In comparison, identical twins reared together typically differ by 6 IQ points, non-twin siblings differ by 12 points, and complete strangers differ by 16.9 points.
Since women carry two X chromosomes while men carry only one, scientists say there is a higher chance that intelligence-related genes come from the mother. This does not mean fathers do not contribute to intelligence, but it suggests the maternal line may have more influence at the genetic level.
Research on the effect of environment on brain development varies. In other words, according to one study, the genetic effect on intelligence is 75%, while the effect of the environment is 25%, while another study emphasizes that it varies according to age.
