Granted this Hewlett Packard study is a few years old (from 2005) but it seems only more relevant today based on how much time we all spend in front of screens and vast amounts of data and information.
Workers distracted by email and phone calls suffer a fall in IQ more than twice that found in marijuana smokers, new research has claimed. 62% of people checked work messages at home or on holiday. HP warned of a rise in “infomania” or people becoming addicted to texting and email. The firm said new technology can help productivity, but users must learn to switch computers and phones off.
Emailing or phone calls can cause a 10-point drop in IQ – more than twice that found in studies about smoking marijuana! Kind of amazing that information can cause more harm than a plant.
