You can increase cognitive skills that correlate with IQ scores through mentally stimulating activities like reading, puzzles, and learning new things, along with healthy habits such as exercise, good sleep, and proper nutrition, though IQ itself is relatively stable, these practices boost overall brain power, memory, and reasoning, particularly in areas like visuospatial skills and executive control, says Healthline.
How to increase IQ at home
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.
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.
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.
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.
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.

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.
To check your IQ level, take a professionally administered test from a psychologist for accuracy (like WAIS or Stanford-Binet), or try reputable online versions for a general idea, but remember they're estimates; these tests evaluate cognitive skills like problem-solving, memory, and reasoning against a norm group, with 100 being the average score.
Here are 10 habits to incorporate into your daily life to become smarter:
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.
