Answer:
Neuroscientists and psychologists have concluded that the human brain cannot focus on more than one thing at a time. Switching tasks causes our brains to slow down and makes it harder to tune out distractions. Trying to do two things at once, like write an email while talking on the phone, results in interference and splitting our focus as the brain struggles to do two types of communication at once. Scientists say that through MRI brain scans, you can actually see the brain struggling!
Only 2 percent of people can really multitask effectively. Crazy, right? For the other 98 percent, multitasking can do more harm than good. A paper published by the Institute of Psychology says that trying to focus on more than one thing can reduce your productivity by as much as 40 percent and lower your IQ by 10 points. What! Who needs that? The drop in IQ is similar to missing an entire night's sleep.
