You can improve cognitive skills that relate to IQ by consistently engaging in mentally stimulating activities like reading, puzzles, learning new skills (music, language), strategic games (chess), and getting regular exercise, good nutrition, and adequate sleep, though major IQ score changes are difficult as it's partly genetic. Focus on activities that challenge reasoning, memory, and problem-solving to boost overall brain function and IQ test performance, even if general IQ gains are modest.
Processing speed and executive function can improve with regular use of apps that present increasingly difficult logic puzzles and math problems. Physical activity, adequate sleep, and even mindfulness training have been linked to sharper mental performance and better IQ test outcomes.
Meaning of IQ
85 to 115 - Two thirds of us have an IQ in this range: the 'average' IQ is 100. Over 135 - You are in the top 1%.
Yes. However, there is heavy debate over exactly how IQ and intelligence change with age. Studies have demonstrated that a person's fluid intelligence tends to decrease starting in their late 20s, while their crystallized intelligence tends to increase as they grow older.
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.
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.
Here are 10 habits to incorporate into your daily life to become smarter:
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.
There is no evidence that he ever took an IQ test. However, that has not stopped some people from trying to determine how smart he was. According to some sources, Einstein's IQ was probably about 160, which is commonly considered genius level. This number is largely derived from his achievements in physics.
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.
The IQ of an average millionaire is 117 The IQ of an average billionaire is 133 The IQ of an average deca-billionaire is 151 This shows - you gotta be intelligent to get rich!
Is Kim Kardashian's IQ really 190? No—it's a baseless rumor from unreliable sites. No verified score exists; estimates range 95–119 based on her education & career, but her actual IQ remains unknown.
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.
Less sleep lowers IQ scores
According to Coren, scores on intelligence tests decline cumulatively on each successive day you sleep less than you usually sleep. The daily decline is approximately one IQ point for the first hour of sleep loss, two for the next, and four for the next.
What Are the Signs of High Intelligence? Let's Talk!
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.
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. In addition, his SAT scores were amazing. Even though he had a full scholarship to MIT, Woods dropped out to pursue acting.
About 75% of your brain is water, making hydration crucial for sharp thinking, focus, and mood, as even mild dehydration (losing 2% of body water) can impair memory, concentration, and reaction time. The remaining part of the brain is mostly fat, and this water content is essential for creating neurotransmitters and supporting brain function.

How to increase IQ at home
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.
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.
