Intelligence is a measure of a person’s ability to learn, understand, and apply complex concepts and ideas.

It is often measured by standardized intelligence tests, which assess a range of cognitive abilities including memory, reasoning, and problem-solving. However, recent research suggests that intelligence may also be linked to a longer lifespan. This article will explore the current evidence linking intelligence with extended lifespan and examine the possible mechanisms behind this relationship.

What is the evidence linking intelligence with extended lifespan?

Several large-scale studies have found that people with higher intelligence scores tend to live longer than those with lower scores.

For example, a study published in the journal Intelligence analyzed data from over 6,800 men and women who took the Scottish Mental Survey in 1947 at the age of 11. The researchers found that those with higher scores on the intelligence test had a lower risk of death from all causes over the next six decades, even after controlling for other factors such as socio-economic status and health behaviors.

Another study published in the journal PLOS Medicine analyzed data from over 65,000 people in the United Kingdom.

The researchers found that people with higher scores on a test of verbal and numerical reasoning had a lower risk of death from all causes, even after adjusting for age, sex, socio-economic status, and other health-related factors.

Similarly, a study published in the journal Psychological Science analyzed data from over 1,000 men and women who were born in Scotland in 1921 and took an intelligence test at the age of 11.

The researchers found that those with higher scores on the test had a lower risk of death from cardiovascular disease, even after adjusting for other factors such as smoking and physical activity.

Why might intelligence be linked to extended lifespan?

Several possible mechanisms have been proposed to explain the relationship between intelligence and extended lifespan.

One theory is that people with higher intelligence are better able to make healthy lifestyle choices and avoid behaviors that increase the risk of disease and death. For example, they may be more likely to exercise regularly, eat a healthy diet, and avoid smoking and excessive alcohol consumption.

Can intelligence be improved to extend lifespan?

The relationship between intelligence and extended lifespan raises an intriguing question: can intelligence be improved to enhance longevity? While it is not yet clear whether interventions to boost intelligence could directly improve health outcomes, some studies have suggested that certain lifestyle factors may help promote cognitive function and brain health.

For example, regular physical exercise has been shown to improve cognitive function in older adults and may help protect against age-related cognitive decline.

Similarly, a healthy diet rich in fruits, vegetables, and whole grains may help boost brain health and reduce the risk of cognitive decline and dementia.

In addition, some research has suggested that cognitive training programs, which involve practicing mental exercises such as memory games and problem-solving tasks, may improve cognitive function and protect against age-related cognitive decline.

While the evidence for these interventions is not yet robust enough to recommend them for widespread use, they suggest that it may be possible to promote cognitive function and brain health through lifestyle and behavioral changes.

: Conclusion

Intelligence is a measure of a person’s ability to learn, understand, and apply complex concepts and ideas. Recent research suggests that intelligence may also be linked to a longer lifespan.

Several large-scale studies have found that people with higher intelligence scores tend to live longer than those with lower scores. The relationship between intelligence and extended lifespan may be due to a range of factors, including better health behaviors and improved cognitive function and brain health.

While it is not yet clear whether interventions to boost intelligence can directly improve health outcomes, lifestyle and behavioral changes such as regular exercise and a healthy diet may help promote cognitive function and brain health.
