HOW ACCURATE ARE IQ TESTS? 

After conducting the largest ever study of intelligence, researchers concluded that far from indicating how clever you are, IQ testing is actually rather 'meaningless'.

In a bid to investigate the value of IQ, scientists asked more than 100,000 participants to complete 12 tests that required planning, reasoning, memory and attention.

They also filled in a survey on their background.

Scientists from Canada's Western University in Ontario discovered that far from being down to one single factor, what is commonly regarded as intelligence is influenced by three different elements - short-term memory, reasoning, and verbal ability.

But being good at one of these factors does not mean you are going to be equally gifted at the other two.
