    And a really good blog article "Biggest Intelligence Test Exposes the Limits-of-IQ" on the topic.

    Largest ever assessment of IQ, bolstered by selected fMRI testing.  Original paper in Neuron.

    No one component, or ‘IQ’, explained all the variations revealed by the tests.

    To bolster our results, Adrian and I used a $5 million brain scanner, which relies on a technique known as functional magnetic resonance imaging (fMRI), to study 16 participants as they carried out all 12 tests.  We found that each of the three different factors identified by the analysis did indeed correspond to a different brain network: these differences in cognitive ability map onto three distinct circuits in the brain.

    The results disprove once and for all the idea that a single measure of intelligence, such as ‘IQ’, is enough to capture all of the differences in cognitive ability that we see between people. Instead, several different brain circuits contribute to intelligence, each with its own unique capacity. A person may well be good in one of these areas, but they are just as likely to be bad in the other two.

    The work was performed by Adrian Owen and Adam Hampshire at the University of Western Ontario - they were previously at University of Cambridge, where the next stage of their research will continue with a new version of the test.
    We are now launching a new version of the tests here. To ensure we do not bias the results of the new tests, we can’t say much about the agenda other than that there are many more fascinating questions about the true nature of intelligence that we want to answer.
