Your IQ doesn't have a single peak age; different mental abilities peak at different times, with fluid intelligence (problem-solving) peaking in the mid-20s, while crystallized intelligence (accumulated knowledge) continues to grow into middle age, often peaking in the 40s or 50s, creating a lifelong cognitive peak in the mid-20s to 40s for overall cognitive function, despite declines in processing speed later in life.
Research Results. It has been shown that scores on IQ tests actually decrease with age. This chart shows how scores on Wechsler IQ tests peak between 25 and 29 years old, then decline throughout the rest of adulthood, with a decline becoming more steep after the age of 70.
An IQ of 120, therefore, implies that the testee is brighter than about 91% of the population, while 130 puts a person ahead of 98% of people. A person with an IQ of 80 is brighter than only 9% of people, and only a few people score less than 60.
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.
An IQ of 72 is considered borderline intellectual functioning, falling below the average range (90-109) but not quite low enough for a diagnosis of intellectual disability (typically below 70). It signifies slower learning, potential difficulties with complex concepts, and a need for more support in daily living and academic skills, placing someone in the bottom few percentiles of the population.
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).
Additionally, a higher percentage of individuals with Asperger syndrome had IQ scores above 70 compared to individuals with autism. This indicates that individuals with Asperger syndrome are more likely to have intellectual abilities above the threshold for intellectual disability.
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!
Rappers IQ's, Jay Z has an IQ of 148, Kendrick Lamar has an IQ of 129, Tupac Shakur IQ is 124, Lil Wayne IQ is 120, and last is Eminem with 110 IQ. Archived post.
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.
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.
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%.
Stephen Hawking never officially revealed his IQ, and often dismissed the metric, famously saying, "People who boast about their IQ are losers". While estimates place his IQ around 160, a genius level, this is speculative; Hawking emphasized that creativity, persistence, and passion for science were more important than a single score, despite his profound impact on physics.
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.
A number of prominent authorities on intelligence insist that an individual's IQ is highly stable and resists efforts to alter it.
No, an IQ of 97 is not considered dumb; it falls within the average range (90-109), indicating typical cognitive abilities, and is very close to the theoretical average of 100, meaning you're more intelligent than about 42% of people and have normal intelligence, just slightly below the mean, but well within the typical range for most adults.
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).

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.
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.
She was a very smart girl (with an IQ of 154), became a bookworm, and once was told that a suitable job for her (and her brains) was to become a lawyer. However, her first love was still the black-and-white movies, especially those featuring.
Kanye West is often described as highly intelligent because he thinks beyond traditional boundaries. He combines creativity, business sense, and cultural awareness in a way that reshapes music, fashion, and public conversation.
Marilyn Monroe had an IQ of 168! Despite being typecast as the quintessential “dumb blonde,” she was highly intelligent and had a deep love for literature. She owned over 400 books, including works by Dostoevsky, Freud, and Hemingway, and even took literature courses at UCLA.
Manifest grants for people with an intellectual disability
In order to make a manifest grant of DSP, the medical evidence in support of the claim must include an assessment of intellectual function that clearly indicates an IQ of less than 70.
The "6-second rule" for autism is a communication strategy where a speaker pauses for about six seconds after asking a question or giving information, giving the autistic person extra time to process it without feeling rushed, which helps reduce anxiety and allows for a more thoughtful response, reducing frustration for both parties. Instead of repeating or rephrasing, which can be confusing, you wait, and if needed, repeat the exact same words after the pause.
