New algorithm that may predict your intelligence
New York, June 30: Be careful if you lie about your IQ as researchers have developed a machine-learning algorithm that may tell how smart you are by looking at a scan of your brain.
The study showed that the new computing tool can predict a person's intelligence from functional magnetic resonance imaging (fMRI) scans of their resting state brain activity.
The fMRI develops a map of brain activity by detecting changes in blood flow to specific brain regions.
"We found if we just have people lie in the scanner and do nothing while we measure the pattern of activity in their brain, we can use the data to predict their intelligence," said co-author Ralph Adolphs from the California Institute of Technology (Caltech).
To train their algorithm on the complex patterns of activity in the human brain, the researchers downloaded the brain scans and intelligence scores from almost 900 individuals.
The researchers found that after processing the data, the algorithm was able to predict intelligence at statistically significant levels across the subjects.
"The information that we derive from the brain measurements can be used to account for about 20 per cent of the variance in intelligence we observed in our subjects," said Julien Dubois from the Cedars-Sinai Medical Centre.
In predicting intelligence from brain scans, the algorithm is doing something that humans cannot, because even an experienced neuroscientist cannot look at a brain scan and tell how intelligent a person is, the researchers said.
The researchers also conducted a parallel study, using the same test population and approach, that attempted to predict personality traits from fMRI brain scans.
The personality test they used divides personality into five scales -- openness to experience, conscientiousness, extraversion, agreeableness, neuroticism.
However, it has turned out to be much more difficult to predict personality using the method the team used for predicting intelligence.
The two studies are yet to be published in the separate journals Personality Neuroscience and Philosophical Transactions of the Royal Society.

Four cops suspended after man escapes from custody, gets hit by truck in Ghaziabad
Ghaziabad (UP) (PTI): The Ghaziabad Police has suspended four personnel over presumed negligence and dereliction of duty after a detainee suffered severe injuries while allegedly fleeing from custody, a police official said on Friday.
Assistant Commissioner of Police (Modinagar) Bhaskar Verma said one Amit Kumar (35), an outsourced employee at Patla Nagar Panchayat, was allegedly drinking alcohol with three of his friends at a public place on Tuesday night. When Niwari police station arrived and reprimanded them, an altercation ensued, and Amit was subsequently detained.
While police were taking him for medical examination at Community Health Centre Muradnagar, Amit reportedly jumped from the moving police vehicle near the health centre to escape. As he ran towards the Delhi-Meerut highway, he was hit by an oncoming truck and sustained severe injuries. He was rushed to Yashoda Hospital in Nehru Nagar, where he is currently undergoing treatment in the ICU.
The police personnel allegedly failed to report the truck accident to their senior officers initially, claiming instead that Amit had fallen and injured himself while attempting to flee.
The incident sparked outrage among locals and the family of the detainee, who alleged that Amit was brutally thrashed while in custody.
On Thursday, protesters gathered outside the Niwari police station for nearly an hour, raising slogans against the police. The situation was eventually brought under control after officials assured that stringent action would be taken.
In response, a delegation of Rashtriya Lok Dal (RLD) leaders met Police Commissioner J Ravindra Goud to submit a formal complaint demanding accountability for the Niwari police station personnel.
On Thursday evening, Deputy Commissioner of Police (Rural) Surendra Nath Tiwari issued the suspension order against Patla police outpost in-charge Sub-Inspector Lokendra, Sub-Inspector Shaid Khan, Head Constable Sachin Mohan and Constable Narendra.
Additionally, the role of Niwari Station House Officer KK Maurya is under investigation, and a departmental inquiry has been initiated against the errant personnel, Verma said.
