Best friends’ brains light up the same way, says study

PARIS: Dating sites would be well-advised to add “brain activity” as a compatability criterion, according to a study released Tuesday showing that close friends have eerily comparable neural responses to life experiences.

“Our results suggest that friends process the world around them in exceptionally similar ways,” said lead author Carolyn Parkinson, director of the Computational Social Neuroscience Lab at the University of California in Los Angeles.

Using magnetic resonance imaging (MRI) to compare which regions of the brain lit up as 42 volunteers watched short clips from news reports, music videos, comedy skits and documentaries, researchers were able to identify who among them were friends.

The closer the relationship, the more alike the neural patterns in parts of the brain governing emotional response, high-level reasoning, and the capacity to focus one’s attention.

“Friends had the most similar neural activity patterns, followed by friends-of-friends,” the authors said in a statement.

“You can predict who people are friends with just by looking at how their brains respond to the video clips.”

The 14 brief excerpts included journalists debating whether then US President Barack Obama should use humour in his speeches; a sentimental music video about a social outcast with a facial deformity; a documentary about baby sloths in Costa Rica; and scenes from a gay wedding.

Scientists long ago understood that “birds of a feather flock together” when it comes to human social networks, with people attracted more easily to those of the same age, physical appearance and ethnic background, as well as other demographic categories.

– Online echo chambers –

This tendency extends to social networks too, according to the study, published in the journal Nature Communications.

From an Darwinian perspective, evolutionary psychologists argue, the “like-with-like” principle favour social cohesion, empathy and frictionless collective action.

The relationships we forge with individuals who are clearly different from us — not of our “tribe” — tend to be practical, task-oriented and short-lived, research has shown.

But seeking out peas from the same pod has a downside that is amplified in the digital age, said senior author Thalia Wheatley, a professor of psychology and brain science at Dartmouth University in Massachusetts.

“The cost of surrounding ourselves with only like-minded people is the creation of echo-chambers and polarisation,” she told AFP.

“This can be exacerbated by online communities that offer a constant diet of information that only confirms what people already believe.”

One question not answered by the study is whether we naturally gravitate toward people who see the world the same way we do, or whether similarity — including the way our brains light up — springs from shared experience.

Most likely, it is a combination of the two.

“We are a social species and live our lives connected to everybody else,” said Wheatley.

“If we want to understand how the human brain works, then we need to understand how brains work in combination — how minds shape each other.”

K-Electric fined Rs2 mn over weak power supply system

ISLAMABAD: The National Electric Power Regulatory Authority (Nepra) on Wednesday imposed a fine of Rs2 million on the K-Electric. According to a statement issued by the power regulatory authority, the K-Electric was penalized over non-compliance of performance standards, particularly its failure to restore power supply within the prescribed time frame and to ensure the safety of public in Karachi. Quoting media reports, it said large swathes of Karachi remained without electricity due to the tripping of almost 700 feeders during rainy weather in June last year, which resulted in long power blackouts ranging from 24 hours to 48 hours in almost 50% areas of Karachi. Further, there were also reports of fatal injuries to some people owing to electrocution. The Nepra took notice of the situation in Karachi and directed the K-Electric to immediately provide a detailed report on the tripping of feeders and electrocution incidents along with preventive and corrective steps taken by K-Elec...

Qatar to hike minimum wage ‘by end of year’

DOHA: Qatar could increase the minimum wage for migrant workers by the end of 2018, unions predicted on Monday, as the 2022 World Cup host seeks to push through labour reforms. It would be the first change to the monthly wage since its introduction by the gas-rich Gulf state last November. “By the end of the year we expect a new minimum wage to be set, that’s good news,” said Sharan Burrow, general secretary of the International Trade Union Confederation. Burrow did not name a figure but said the new wage would be calculated by assessing a “basket of goods”. She was speaking after meeting Qatar’s labour minister, Issa al-Jufali al-Nuaimi, and other government officials in Doha over the past two days. The minimum wage was set at 750 riyals a month ($206, 170 euro) on its introduction. In addition to the salary, labourers receive free accommodation, food and healthcare plans, covered by employers. The 750-riyal figure has been criticised as too low. “We believe it is not good e...
