Also, is intelligence more of a genetic or environmental trait?” If a person with a high IQ marries someone with a lower IQ, their kids could have most any IQ. The same is true for two high IQ parents (although their kids will tend to have higher IQs).
Intelligence has a very high heredity component, so often times the parents of smart people are smart. But this is not a necessity. Rare gene combinations can often lead to interesting results and two very smart people might have a really average child, we call this statistical regression to the mean.
A child was born smart or not, and little could be done to change that. More recent research has upended that notion, and shown that encouraging parents to adopt a so-called growth mindset leads to better educational outcomes for their children.
IQ of a Child
The characteristics of who a parent is and the way he or she decides to raise his or her children may play a role in a child's intellectual development. The amount of education a parent has had, the home environment a parent establishes, and the parent's culture may all have an effect on a child's IQ.
Although IQ differences between individuals have been shown to have a large hereditary component, it does not follow that disparities in IQ between groups have a genetic basis. The scientific consensus is that genetics does not explain average differences in IQ test performance between racial groups.
An average person scores 100 on an IQ test using the Stanford-Binet IQ scale. A score of 137 to 160 is considered the top 1 percent to .
But genetics can explain the wide range of possible IQs too because so many different genes are involved in developing and running a brain. It is possible, for example, to inherit all the higher IQ genes from each parent and leave the lower IQ ones behind. Now the child will be brighter than the parent.
Empirical evidence suggests that especially parental education, parental income, and maternal IQ are important predictors of intelligence. Parental education together with maternal IQ and the child's sex were found to account for 24% of the variance in IQ at age 5 [6].
A new study shows that first-born children tend to be smarter than their siblings and second-born children are more likely to cause trouble. The University of Edinburgh study reported that the oldest child tends to have a higher IQ and thinking skills than their younger siblings.
&ween Parents and Children
The average IQ difference between a parent and his (or her) child is the same as the difference between siblings-that is, about 12 IQ points. The difference between a child and the average of both of his parents' IQ's is about 10 points.
A University of Edinburgh study shows first-born children have higher IQs and better thinking skills than their siblings. The study says that shows first-born kids get more mental stimulation than their brothers and sisters.
Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors.
Researchers find that brain development peaks years later for children with the highest IQs. Smart children have a different rhythm in their heads — a seesaw pattern of growth that lags years behind other young people — say government scientists who mapped the brains of hundreds of children.
Joseph Hotz and Juan Pantano and they found that the oldest kids had higher IQs, performed better at school in terms of grades, and are believed to be more accomplished.
Giftedness can create problems and conflicts; being a gifted child can also mean difficulty socializing with age peers, thinking styles that don't always mesh well with the demands from the environment, even children who see themselves as little adults, challenging teachers and parents.
Causes of Genius
Scientists don't know exactly what causes someone to be a genius. There is probably a genetic component to your level of intelligence. Certain types of genes influence how much intellectual power you have. Your child's genetic influences affect their motivation, confidence, and other traits.
Like, is Elon Musk a genius? It answered, Elon Musk's IQ is reported to be 155, which is very high compared to the average of 100.
Adhara Pérez Sánchez of Mexico City, has an IQ higher than Albert Einstein. The child prodigy is receiving her master's degree in engineering soon. Adhara aspires to be an astronaut in NASA. Adhara has an IQ of 162, which is higher than Einstein and Stephen Hawking.
The genius child, Adhara Pérez Sánchez, has an IQ that beats Albert Einstein — whose IQ is estimated to be around 160. Adhara finished her High School education at the very young age of seven. Mirror UK reports that the genius girl will soon be awarded a masters and is currently working with the Mexican Space Agency.
This allows consideration of the rate of change and recovery being made. The average child's IQ is not stable until around four years of age. It may be much later in children who were born early or who have significant health issues.
While you can test a child's IQ as early as 2 years and 6 months of age, the results may not be accurate and may in fact change with age. The best time to test IQ in children is between ages 5 and 8.
For adults between 18 and 19 years of age, the average IQ score is 105, which also denotes normal or average intelligence. The average score for people between 20 and 24 years of age is 99, which also denotes normal or average intelligence.
Research reflects that giftedness does “run in families”: for a gifted child, their genetically-related relatives — siblings and/or parents — are likely to also be gifted, though there are plenty of exceptions.
Just as having a high IQ doesn't ensure success, having an average or low IQ doesn't ensure failure or mediocrity. Even if you have what is considered a low IQ, you may be smart in many other ways and have many other talents and abilities that aren't reflected on a single test.
85 to 114: Average intelligence. 115 to 129: Above average or bright. 130 to 144: Moderately gifted. 145 to 159: Highly gifted. 160 to 179: Exceptionally gifted.
