Mulititasking and distraction hurts IQ

That’s interesting.

Dr. Glenn Wilson, a psychiatrist at King’s College London University, monitored the IQ of workers throughout the day.
He found the IQ of those who tried to juggle messages and work fell by 10 points — the equivalent to missing a whole night’s sleep and more than double the 4-point fall seen after smoking marijuana. [Dr. Wilson did not originally make the comparison to marijuana. – eds.]
“This is a very real and widespread phenomenon,” Wilson said. “We have found that this obsession with looking at messages, if unchecked, will damage a worker’s performance by reducing their mental sharpness.
“Companies should encourage a more balanced and appropriate way of working.”
Wilson said the IQ drop was even more significant in the men who took part in the tests.
