Does one believe that people with a high IQ have the most brainpower? Since IQ tests were based on measurements that were developed more than a century ago, they mainly emphasized such skills as knowledge, and memory and speed in ability to perform mathematical equations. Of course having those skills were important in the days before computers and the Internet. So, now, what is considered the criteria for having high intellect?
What is more important is to know how to use knowledge in novel ways and bringing together facts from disparate areas to create original ideas. As Einstein said, “Imagination is more important that knowledge. Knowledge is limited. Imagination encircles the world.”
Now, when it comes to multitasking, which so many jobs require one to perform, one would have to be quite intelligent, and one might think that multitasking gives one’s brain a good workout. However, that’s not really true. Obviously, the specific tasks that need to be performed would require one’s knowledge and ability, but as for multitasking, the concept that it is a good workout for one’s brain is simply not true. When one multitasks, the brain has to call on different regions to handle the load. It works inefficiently because the communication is not synchronized. When one uses one’s brain this way, the frontal lobes become fatigued. This slows efficiency and decreases performance.
In order to deal with this issue, whatever one is doing, one should focus on that and nothing else for at least fifteen minutes. One will think more clearly in those fifteen minutes than someone who multitasks for an hour.
Unfortunately, we live in the age where many jobs do require the ability to multitask. So, it’s obvious one should take mini-vacations within the day. Take a break and perhaps meditate, go for a walk, or bounce a ball.
