In our daily life, many behaviors that we don't pay attention to will invisibly reduce our IQ. That's why creativity and mental acuity decrease after a long time working in a certain job.
Selfie affects IQ
Fairfield University found that the brain must simultaneously consider the facial state and shooting behavior when taking selfie, which will distract the memory. This is known as "damage effect of photographing function". The damage is mainly manifested in forgetfulness, difficulty in concentrating when doing things, and frequent selfie even affects the IQ!
Masturbation affects IQ
The German Jews with very strict abstinence regulations have the highest IQ, with an average of 130, while the tribes in Central Africa and South Africa with the most indulgence have the lowest IQ, with an average of about 50! But there is no exact scientific basis.
Frequent text messages affect IQ
Researchers found that in daily life and work, many people are restless if they don't receive text messages, e-mails or phone calls. Some people even said that if the mobile phone didn't ring every half an hour, he would involuntarily pick it up to see if it was out of power. In a subsequent IQ test, the researchers found that those busy with text messages and e-mails scored significantly lower. Scientists call this phenomenon 'infomania'. They believe that SMS and e-mail communication are on a virtual platform. If people indulge in it, they will greatly reduce the chance of contacting with the outside world, which will inevitably reduce people's cognitive ability and IQ of society.
