Yes, substantial research, including large meta-analyses, shows that schooling significantly increases IQ scores, with an estimated gain of 1 to 5 IQ points for each additional year of education, making education one of the most effective ways to boost cognitive ability. These effects are long-lasting, apply across different cognitive areas, and are evident even after controlling for innate intelligence, with policy changes or age cutoffs revealing clear links between time spent learning and higher scores.
Intelligence test scores and educational duration are positively correlated. This correlation could be interpreted in two ways: Students with greater propensity for intelligence go on to complete more education, or a longer education increases intelligence.
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.
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.
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%.
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.
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.

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.

For example, fatigue, drug use or a psychiatric condition can affect an individual's performance. This means that IQ tests are not always reliable.
Traditionally, cognitive or intellectual functioning has been measured through the intelligence quotient (IQ) tests, with an IQ of less than 70 recommended for a clinical diagnosis of Intellectual Disability.
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.
“Many Gen Z students feel they were told college was the only path, only to see people with strong degrees underemployed or overlooked,” Tallo CEO Allison Danielsen told Fortune. Plus, they're “questioning whether college still delivers real value.”
Recent research out of Harvard, Stanford, and the University of Pennsylvania suggests that while raw IQ may not increase dramatically, certain cognitive skills that contribute to performance on IQ tests can be improved through targeted training.
Einstein once said, "Education is not the learning of facts, but the training of the mind to think." These words encapsulate a fundamental truth about education: it goes beyond the mere accumulation of knowledge and focuses on nurturing critical thinking, creativity, and problem-solving skills.
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.
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.
The vast majority of people in the United States have I.Q.s between 80 and 120, with an I.Q. of 100 considered average. To be diagnosed as having mental retardation, a person must have an I.Q. below 70-75, i.e. significantly below average. If a person scores below 70 on a properly administered and scored I.Q.
