Why texting harms your IQ

　　The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana.

　　That is the claim of psychologists who have found that tapping away on a mobile phone or computer keypad or checking them for electronic messages temporarily knocks up to ten points off the user’s IQ. 

　　This rate of decline in intelligence compares unfavourably with the four-point drop in IQ associated with smoking marijuana, according to British researchers, who have labelled the fleeting¹ phenomenon of enhanced stupidity as “infomania”. 

　　Research on sleep deprivation² suggests that the IQ drop caused by electronic obsession³ is also equivalent to a wakeful night. 

　　Infomania is mainly a problem for adult workers, especially men, the study commissioned by Hewlett Packard, the technology company, has concluded. 

　　The noticeable drop in IQ is attributed to the constant distraction⁴ of “always on” technology when employees should be concentrating on what they are paid to do. Infomania means that they lose concentration as their minds remain fixed⁵ in an almost permanent state of readiness to react to technology instead of focusing on the task in hand. 

　　Workers lose productivity by interrupting a business meeting and disrupt social gatherings⁶ because of their infirmity, the report said. 

　　The brain also finds it hard to cope with juggling⁷ lots of tasks at once, reducing its overall effectiveness, it added. And while modern technology can have huge benefits, excessive use can be damaging not only to a person’s mind, but to their social life. 

　　Furthermore, infomania is having a negative effect on work colleagues, increasing stress and dissenting⁸ feelings. Nine out of ten polled thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude. Yet one in three Britons believes that it is not only acceptable, but actually diligent⁹ and efficient to do so. 

　　The effects on IQ were studied by Dr Glenn Wilson, a University of London psychologist, as part of the research project. “This is a very real and widespread phenomenon,” he said. “We have found that infomania, if unchecked, will damage a worker’s performance by reducing their mental sharpness. Companies should encourage a more balanced and appropriate way of working.”
