Researchers at the University of Western Ontario say intelligence is way more than a number and declare the concept of IQ "a myth." Scientists instead believe that three factors — reasoning, short-term memory and verbal ability — combine to form human intelligence. The researchers said no singular component, or IQ, explains everything.
“When we looked at the data, the bottom line is the whole concept of IQ — or of you having a higher IQ than me — is a myth,” Dr. Adrian Owen, the study’s senior investigator, told the Toronto Star. “There is no such thing as a single measure of IQ or a measure of general intelligence.”
The research was published today in the journal Neuron.
For the study, scientists asked 100,000 participants from around the world to complete 12 cognitive tests. Scanning their brains at the same time, researchers said they showed that differences in cognitive ability are related to distinct brain circuits.
