Food for thought

Intelligence is an intellectual capacity, but it is an intricate concept to define.
A lot of factors can affect the room available for someone’s intelligence to be exercised, or lack thereof, which could potentially prevent them from doing so.

Think of it as an occupying space in our brain that can move freely and expand into logic and problem-solving, or whether it gets blocked due to some external factors such as the environment that the brain is exposed to, which could take up some space to block that free movement.

The IQ test in a nutshellWhat really is an IQ and what does it do for me?

IQ, Intelligence Quotient, is a scale that measures the volume of intellectual ability in the senses of rational thought and quick problem solving – essentially, good wit.
