The noticeable drop in IQ is attributed to the constant distraction of "always on" technology, when employees should be concentrating on what
they are paid to do. They lose concentration as their minds remain fixed in an almost permanent state of readiness to react to technology instead of
focusing on the task at hand.
The brain also finds it hard to cope with juggling lots of tasks at once, reducing its overall effectiveness, the study has found. And while modern
technology can have huge benefits, excessive use can be damaging not only to a person's mind, but also their social life.
Eighty volunteers took part in clinical trials on IQ deterioration and 1100 adults were interviewed.

While i can see this drop in IQ happening spasmodically in a stressful work situation, i think if that person took a holiday and 'chilled out', and
then did a controlled IQ test i reckon the results would be almost the same as the 'pre drop' IQ score. (provided that was known)
As for using the 'net for education, leisure, i would assume it could increase ones IQ .
Of course, it depends on what sites you frequent.
