Intelligence, or the ability to learn, think, and solve problems, is a complex trait that is influenced by our genes (what we inherit from our parents) and our environment (the world around us). Understanding how these factors work together can help us better support everyone’s learning and development.
Genes and intelligence
What is intelligence?
Intelligence involves various mental abilities, such as understanding complex ideas, learning quickly, and adapting to new situations. IQ (intelligence quotient) tests are often used to measure these abilities, although intelligence is more than just test scores. It is shaped by many different factors throughout people’s lives.
How do genes affect intelligence?
Genes play an important role in intelligence. Studies of twins have shown that the IQs of identical twins (who share all their genes) are more similar than those of fraternal twins (who share about half their genes). This shows that genetics can strongly influence intelligence. Scientists have also discovered specific genes linked to intelligence, but it’s not just one gene; Instead, many genes each have a small effect.
How does environment affect intelligence?
While genes are important, environment is equally important in shaping intelligence. Environmental impacts include a variety of factors, such as:
Prenatal and early life:
Conditions in utero and early childhood can significantly affect intelligence. For example, good nutrition during pregnancy and avoiding harmful substances such as alcohol can promote better brain development. Likewise, proper nutrition and health care in early childhood are critical for cognitive development.

Family and Parenting:
A child’s home environment and parenting style play an important role in cognitive development. Children who grow up in a stimulating environment with books and educational toys, and who receive active parental involvement, tend to develop better cognitive skills.
The impact of genes and intelligence on education:
Schooling provides important opportunities for learning and cognitive development. A quality education, including effective teachers and a good curriculum, can significantly improve a child’s IQ. Early childhood education programs such as preschool can have lasting benefits for intelligence.
Socioeconomic status (SES):
Children from wealthier families typically have more resources, better education, and healthier environments, all of which support cognitive development. On the other hand, children from poor families may face challenges such as malnutrition and limited educational opportunities, which may hinder cognitive development.
Cultural factors—genes and intelligence
Different cultures value different skills and types of knowledge, which can shape cognitive development in unique ways. For example, some cultures may emphasize collective problem solving, while others focus on individual achievement.

Gene-environment interaction
Genes and environment do not act separately; They interact in complex ways:
Gene-environment interactions:
The impact of environmental factors may depend on a person’s genetic makeup. For example, a child with a genetic tendency to learn quickly may benefit more from a good educational environment than a child without this genetic tendency.
Gene-environment correlation:
People’s genetic predispositions can influence the types of environments they experience. For example, a child with a natural interest in reading may seek out books that improve their reading skills and further enhance their intelligence.
impact on society
Understanding the balance between genetic and environmental influences on intelligence can guide educational practice and social policy:
Educational Program:
Tailored educational interventions can help maximize each child’s potential. Programs such as early childhood education and gifted education can address different cognitive needs. Improving educational resources in underserved areas can help reduce the impact of socioeconomic disadvantage on intelligence.
Social and financial support:
Policies that reduce economic inequality can improve conditions for cognitive development. Ensuring access to quality health care, good nutrition, and a safe living environment supports cognitive development. Financial support for low-income families and community programs that provide educational opportunities can also have a big impact.
Ethical Considerations:
It is important to avoid thinking that intelligence is fixed or determined solely by genetics. Intelligence is determined by many factors, and everyone has the potential to grow and develop. Promoting a balanced perspective that recognizes genetic and environmental contributions can help create a fair and inclusive society.
in conclusion
Both genetics and environment play crucial roles in shaping intelligence. While our genes provide the foundation for our cognitive abilities, our experiences and environment help develop and enhance these abilities. By understanding and addressing the factors that influence intelligence, we can support everyone to reach their full cognitive potential and promote a more equitable society.
Q: What exactly is intelligence?
Answer: Intelligence is the ability to learn, think critically, solve problems, and adapt to new situations. It is measured through tests such as IQ tests, but also includes many other skills and abilities.
Q: How much of our intelligence comes from our genes?
A: Genetics play an important role, and studies show that approximately 50 to 80 percent of intelligence can be attributed to our genes. However, it is affected by many genes, each of which has a small effect.
Q: Does a person’s environment change his or her intelligence?
Answer: Yes, environment can significantly affect intelligence. Factors such as education, family support, nutrition, and overall living conditions all play important roles in cognitive development.
Q: Are children from wealthy families always smarter?
Answer: Not necessarily. While children from wealthy families often have more resources and opportunities that can improve their intelligence, children from any background can achieve high intelligence with the right support and environment.
Q: Does school really have a big impact on intelligence?
Answer: Of course. Quality education, great teachers, and a stimulating learning environment are essential for cognitive development, leading to higher IQ scores and better problem-solving skills.
Question: Does the parenting style of parents affect children’s intelligence?
A: Yes, positive and engaging parenting, such as reading to children, playing educational games, and encouraging curiosity, can significantly enhance cognitive development.
Q: Are there specific genes that make people smart?
Answer: There are many genes related to intelligence, but there is no single “intelligence gene”. It is a combination of many genetic factors, each of which contributes a small amount to overall cognitive ability.
Q: How does culture affect intelligence?
Answer: Different cultures value different skills and types of knowledge, which can shape intellectual development in unique ways. For example, some cultures may emphasize teamwork and problem solving, while others focus on individual achievement.
Question: Can early childhood education programs help or change intelligence through genes?
A: Yes, early childhood education programs like preschool provide important opportunities for cognitive development and can have lasting positive effects on intelligence and academic success.
Q: Is intelligence fixed, or does it change over time due to genes?
Answer: Intelligence is not fixed and changes over time. Both genetic factors and environmental experience contribute to its development, and under the right conditions, people can continue to learn and grow intellectually throughout their lives.
