Does Email Cause IQ Loss?
A widely reported story
last week stated that a study conducted by Hewlett Packard found that "Workers distracted by email and phone calls suffer a fall in IQ more than twice that found in marijuana smokers." Sounded like bad news for people like myself who are constantly checking email. But Mind Hacks
has examined the study a little more closely and found its results aren't all they're cracked up to be. What the test actually found is that people do worse on IQ tests if they're simultaneously trying to answer email and phone calls. Which isn't surprising. But this 'IQ loss' only lasts for as long as the distractions last. In other words, you're not really losing any intelligence. Reading email simply stopped people from focusing on the test.
