On average, the male brain is about 10-15% larger than the female brain, a recurring finding in neuroscientific studies. However, when asking, "Do males and females have different sized brains?", the answer is more complex, as size is not the most telling indicator of intelligence or function.

For generations, head circumference has been used by healthcare providers as a marker of a child's brain development and overall well-being. But beyond early childhood, the question, **Does head size mean anything?**, is complex, with its significance tied more to developmental patterns than to adult capabilities.

Genetics account for a large portion of infant head circumference variability. Beyond initial growth, the popular misconception is that a bigger head directly correlates with higher intelligence. But is there an advantage to having a big head, or is it simply a matter of genetic lottery?

According to a 2017 study that examined genetic and health data from 500,000 individuals, babies born with larger-than-average head circumferences were more likely to score higher on cognitive tests later in life. So, are there any benefits to having a big head beyond this potential association, and what do these links truly mean for general health?

According to the Davidson Institute, giftedness is a brain-based difference that can affect an individual's intellectual, emotional, and social development. A common question that arises is: **Is 95 percentile gifted?** This percentile is often a qualifying score in academic settings, but understanding its true meaning requires looking beyond a single number to consider overall well-being.

According to the World Health Organization, adequate nutrition and physical activity are fundamental for healthy growth and development, including the cognitive kind. This powerful connection answers the question of **how do health and physical development affect intelligence**, influencing brain function and intellectual capacity from infancy to old age.

Genetics is a primary cause of head size variation, much like the size of your feet or the shape of your nose. So, does having a bigger head mean anything significant for your overall health and well-being? The answer depends heavily on the underlying cause and any accompanying symptoms.

The average IQ score is 100, and knowing your own can provide insight into your cognitive strengths and weaknesses. But **How do I check my IQ myself** effectively, and what are the most reliable methods for a personal assessment? This article explores the landscape of self-administered tests and the critical distinctions to consider.

Despite persistent myths in popular culture, particularly in East Asia, scientific evidence shows no correlation between a person's blood type and their intelligence level. This definitively answers the question of which blood type has the highest IQ: none of them.

For centuries, the image of the bespectacled intellectual has persisted, but a significant body of research reveals a consistent correlation between myopia (nearsightedness) and higher cognitive function, prompting the question: **Does poor eyesight mean higher IQ**?
