SAEDNEWS: Science shows that intelligence takes different forms at different stages of life. Children often excel in creativity and language learning, young adults tend to be strong in problem-solving and rapid learning, while older adults often demonstrate greater wisdom and accumulated knowledge.
According to Saednews, Have you ever wondered at what age our mental abilities reach their peak? Is an imaginative 8-year-old child smarter, a highly skilled 30-year-old engineer, or an experienced 65-year-old chess master? It is a question many of us have probably asked ourselves. To explore the answer, let’s begin with a story.
Amir is preparing for a major mental competition called “Battle of the Brains” and has to choose the best teammate. His options are:
Leila, age 8: Bilingual and exceptionally creative.
Bamdad, a young engineer: A satellite design engineer who can recite 100 decimal places of pi from memory.
Mohammad, age 65: A neighborhood chess champion with remarkable experience.
It is a difficult choice, isn’t it? Answering the question, “Who is smarter?” is even more difficult because, according to modern definitions, intelligence is not a one-dimensional concept that can be measured by an IQ test alone.
Intelligence consists of many different abilities, including creativity, memory, learning, problem-solving, and wisdom. Interestingly, scientific evidence suggests that our brains may be particularly capable in different areas at different stages of life.
During the early years of life, the brain goes through a period of explosive growth known as synaptogenesis. During this process, more than one million new neural connections can form every second. The brain then strengthens the connections that are supported by experience while pruning weaker ones.
Synaptogenesis is the biological process through which new connections, or synapses, form between nerve cells. This process, particularly during early childhood, helps establish the brain’s neural architecture for learning, memory, and adaptation to the environment.
This development allows children to excel in certain areas:
Language learning: Children’s brains are highly receptive to language acquisition. This is why they can often learn multiple languages relatively easily. This is one of Leila’s strengths.
Creative thinking: The prefrontal cortex, which plays an important role in control, planning, and strategic thinking, is not yet fully developed in children. What may appear to be a limitation can actually provide an advantage in certain situations. Children may be less constrained by established patterns and can come up with unconventional and creative solutions to problems. They can also remain highly flexible during the learning process.
Adolescence and young adulthood are periods of major change for the brain. During this stage:
The prefrontal cortex continues to develop, supporting abilities such as logical and mathematical reasoning, concentration, planning, and problem-solving.
The brain’s reward system is also highly active. This can encourage adolescents and young adults to be curious, adventurous, and willing to seek out new experiences.
The brain’s reward system is a collection of neural circuits involved in motivation, desire, and pleasure. Through the release of key neurotransmitters such as dopamine, it reinforces behaviors and experiences and plays an important role in motivation and learning.
In many ways, the adolescent brain is like a “Swiss Army knife”—ready to learn quickly and acquire a wide range of skills. Young adults also benefit from a more developed prefrontal cortex, which can support efficient performance in activities such as puzzles and word games.
As we age, some cognitive abilities may change. For example, the hippocampus, a brain structure involved in memory, may undergo age-related changes that can make recalling certain details more difficult.
But that is only part of the story. There is a reason behind the familiar expression “older and wiser.”
Older adults have accumulated decades of knowledge and experience. This extensive knowledge can make them particularly valuable when dealing with general information, familiar situations, and tasks that depend on previously acquired knowledge.
This is where the distinction between fluid intelligence and crystallized intelligence becomes important.
Crystallized intelligence refers to the knowledge, skills, and experiences a person accumulates throughout life. It works much like a mental library that becomes richer and broader through learning and experience, allowing us to use information from the past to address present-day problems.
Years of experience can also help older adults recognize patterns and apply established strategies. In activities such as chess, for example, extensive experience may help a player recognize familiar positions and make informed strategic decisions.
The truth is that there is no single age at which a person is universally “the smartest.”
If by intelligence we mean a specific type of ability—such as mathematical, linguistic, creative, or strategic intelligence—different abilities may reach their strongest levels at different points in life.
Intelligence is not a fixed characteristic. Instead, it is a collection of abilities that can develop, change, and reach different levels at different stages of life. Our brains adapt throughout life, emphasizing the skills that are particularly useful for meeting the challenges of each stage.
For example:
Around age 8: strong potential for language learning and creative thinking.
Around ages 16–25: rapid learning, reasoning, and problem-solving can be especially prominent.
Around age 65 and beyond: accumulated knowledge, experience, and wisdom can become particularly valuable.
So, what should Amir do in the “Battle of the Brains”?
Rather than choosing only one person, he could form a multigenerational team. Each member brings unique strengths that the others may not possess.
The real power of intelligence may therefore lie not in finding the single “smartest” age, but in combining different kinds of abilities, knowledge, creativity, and experience across generations.
