Yes, two high-IQ parents can have a child with a lower IQ, primarily due to regression toward the mean (children's traits tend to be closer to the population average than their extreme parents'), the complex inheritance of many genes (polygenic trait), and significant environmental factors like nutrition, stimulation, and health that impact IQ development. While high IQ has a strong genetic basis, inheriting a mix of "high" and "low" IQ genes, combined with environmental influences, means a child's IQ can fall anywhere on the spectrum, even below their parents' scores.
Contrary to popular belief, two parents of higher IQ will not necessarily produce offspring of equal or higher intelligence. Polygenic traits often appear less heritable at the extremes.
In population-based studies, maternal IQ is the single greatest predictor of child IQ [17]. Maternal IQ reflects not only genetic influences, but also incorporates environmental factors affecting the child.
A study by Barrett et al. (2015) shows no clear evidence that either parent influences their child's intelligence more. However, it is well-documented that education and a stimulating environment play crucial roles in shaping intelligence. A supportive environment can help children develop their intellectual abilities.

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.
Stress. A recent theory suggests that early childhood stress may affect the developing brain and cause negative effects. Exposure to violence in childhood has been associated with lower school grades and lower IQ in children of all races.
However the researchers looked at it, first-borns had, on average, an IQ of 1.5 points higher than second-born siblings, who in turn had a 1.5 higher IQ than third-borns and so on.
The "3-3-3 Rule" for kids is a simple mindfulness technique to manage anxiety by grounding them in the present moment: first, name three things they can see; next, identify three sounds they hear; and finally, move three different parts of their body. This engages their senses, shifts focus from worries, and helps them regain control when feeling overwhelmed, like during test anxiety or social situations.
Mitochondrial DNA
Perhaps the most well-known type of DNA you inherit solely from your mother is mitochondrial DNA (mtDNA).
Nurture their mind through reading
Studies show that being read to early on can actually boost IQ by 6-8 points later in childhood. By exposing kids to books, stories, and language through interactive reading sessions, we help build their vocabulary, comprehension, and critical thinking skills right from the start.
Study shows paternal genetics dominate
Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors. Intelligence is challenging to study, in part because it can be defined and measured in different ways.
The single strongest predictor of a person's IQ is the IQ of his or her mother. Also interesting: However, once you get beyond the school environment, it's not a very reliable predictor of performance. Controlling for other factors, people with high IQs do not have better relationships and better marriages.
The 7-7-7 rule of parenting generally refers to dedicating three daily 7-minute periods of focused, undistracted connection with your child (morning, after school, bedtime) to build strong bonds and make them feel seen and valued. A less common interpretation involves three developmental stages (0-7 years of play, 7-14 years of teaching, 14-21 years of advising), while another offers a stress-relief breathing technique (7-second inhale, hold, exhale).
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.
As a result, the thirdborn is often a calmer, more easy going child. The youngest (even of two) tends to be smiley and charming and gets a lot of attention for his sunny disposition.
Red flags in 3-year-old behavior include extreme aggression (hitting, biting), persistent defiance, severe separation anxiety, lack of interest in peers, regression in skills, inability to self-soothe, unusual fears, and significant delays in language or motor skills, suggesting potential issues beyond typical toddler development, like sensory processing problems or ADHD, warranting professional guidance.
1-2-3 Magic is a psychological behavioural intervention that equips parents with tools to manage problem behaviours. 1-2-3 Magic aims to educate parents/carers and even teachers about ADHD and also aids parents with effective strategies, such as communication skills, for handling their child's symptoms.
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.
And it seems that the eldest children tend to choose intellectual achievements. Researchers from the University of Essex in the UK found first borns are 16% more likely to excel academically that their younger siblings [3].
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.
Japan ranks highest in average IQ globally, with an average IQ score of 106.48, according to recently updated data from DataPandas on May 20, 2025. National IQ is influenced by factors such as education, healthcare, nutrition, and economic stability.
8 Bad Habits That Are Killing Your Brain Cells
Dementia risk may increase if you're eating these foods, study says | CNN. Eating ultraprocessed foods such as hot dogs, French fries, sodas, cookies and ice cream could set you on the road to cognitive decline, a new study revealed, but there is a way to overcome the negative impact.
