Overloaded? Multitasking Can Lower Your I.Q By 10 Points

People are worn down with information overload. Though a lot of people find ourselves inundated with enormous quantities of data each day, our fast-paced culture also needs us to make more rapid decisions.

Psychologist and behavioral neuroscientist Daniel Levitin, author of the publication The Organized Mind: Thinking Straight in the Age of Information Overload, state data overload generates daily struggles for our minds, causing us to feel emotionally tired prior to the day’s end.

“Our brains have been equipped to take care of the world how it had been many thousands of years back when we had been hunter-gatherers,” states Levitin. “Back then the sum of information which has been coming was less and it arrived much more gradually.”

The speed at which we are subjected to data now is overpowering to our brains, which have not accommodated quickly enough to readily separate related data from the immaterial at the pace we are asking it to. Because of this, our brains become easily fatigued, and we become forgetful. Using principles of neuroscience, Levitin states we could regain control within our brains by organizing data in a manner that optimizes our mind’s capacity.


As opposed to carrying around on your mind a to-do listing of 20 or even 30 items, set them on paper. Getting information from your mind and in the external world enables you to view it so that you may make decisions regarding what you may handle and in this order.

Rapidly shifting tasks additionally lowers your IQ by 10 points.
When data is simply stored in the mind, the mind has difficulty focusing on what and uses up a lot of its energy trying to remember what is on your record. Writing down your list also helps to encode the data in your brain through using muscle memory.

“Every time you make a determination, it utilizes a few neuro-resources,” states Levitin. The issue is that these neuro-resources are consumed if you are creating an insignificant decision like which pen to use from a drawer of pencils, or something significant like whether to signal a multimillion-dollar thing.

“If you invest your day creating a lot of small decisions and it is time to produce a large important one, you are neurologically depleted,” states Levitin, that calls this happening decision exhaustion. Assessing your significant decision-making activities at the start of the day maximizes your mind’s resources, and will assist you in making better choices.


Being arranged on your physical surroundings reduces the weight in your mind. Have a designated location for generally misplaced items like eyeglasses, keys, and mobile phones. Permit your physical surroundings to function as snacks, relieving the strain on your mind to remember matters.

Levitin cites an instance of denying to take your umbrella. “You hear that the weather report that it is going to rain tomorrow so that you create a mental note to take your umbrella, but if you awake in the morning, you will find a 100 other things in mind,” he states. Lay the umbrella around the doorknob once you listen to the weather reduces the clutter on mind another morning–and you are not as likely to become wet.


How often in a day do you end up checking email when speaking to a customer on the telephone, or answering text messages while at a meeting? You will tell yourself you are multitasking, however, Levitin says multitasking is a misnomer.

“What we are actually doing is quickly shifting our focus from 1 thing to another,” he states. This fast-paced focus seesaw increases the brain’s sugar supply. Glucose is the fuel the brain’s cells will need to communicate together.

Utilizing up the brain’s glucose source by activity shifting means that the brain will attain a degree of fatigue considerably sooner in the day than when we focus on a single thing at a time with ongoing focus. If this does not persuade you, then Levitin says fast shifting tasks additionally lowers your IQ by 10 points.
