Human Intelligence

Human intelligence is the intellectual prowess of humans, which is marked by high cognition, motivation, and self-awareness. Through their intelligence, humans possess the cognitive abilities to learn, form concepts, understand, apply logic, and reason, including the capacities to recognize patterns, comprehend ideas, plan, problem solve, make decisions, retain information, and use language to communicate. Intelligence enables humans to experience and think.

Some studies have shown a direct link between an increased birth weight and an increased intelligence quotient.

According to Rosemary Hopcroft, a sociologist at the University of North Carolina at Charlotte, intelligence is inversely linked with sexual frequency (people with higher levels of education often report lower numbers of sexual partners). In parallel, self-reported intelligence has been linked to unconventional sexual practices and frequent sexual activity, thoughts and fantasies.

A number of studies have shown a correlation between IQ and myopia. Some suggest that the reason for the correlation is environmental, whereby intelligent people are more likely to damage their eyesight with prolonged reading, while others contend that a genetic link exists.
