Can We Upgrade Our IQ?

The IQ of an individual is multifactorial and is determined by a multitude of factors

- 

Nature and nuture work together in determining human intelligence. Human IQ is characterised by a high level of heritability. However, various modifiable environmental factors like education, premature birth, nutrition, pollution, drug and alcohol abuse, mental illnesses, and diseases can have an influence on an individual's IQ by reinforcing or weakening genetic susceptibility.

Although IQ attempts to measure some notion of intelligence, it may fail to act as an accurate measure of "intelligence". IQ tests only examine particular areas of "intelligence", failing to account for certain areas which are also associated with "intelligence" such as creativity or emotional intelligence.
