What if humans could be made twice as intelligent?


BrainAccording to Earl Hunt, professor emeritus of psychology at the University of Washington and president of the International Society for Intelligence Research, approximately one person in 10 billion would have an IQ of 200. With a current world population of 7 billion, there may or may not be one such person alive today, and in any case, his or her identity is unknown. However, the 17th-century genius Isaac Newton, discoverer of gravity, calculus and more, is sometimes estimated to have had an IQ of 200 (though he never took an IQ test). Using him as an archetype, what if we were all a bunch of Newtons? Would the world be much more advanced than it is today?

Haier believes greater intelligence, which he defines as the ability to learn faster and remember more, would be highly advantageous on an individual scale. “Experiencing the world with a higher IQ might be more interesting for most people. They might enjoy reading more, might have a greater depth of appreciation for certain things and more insight into life,” he told Life's Little Mysteries. Furthermore, IQs of 200 would allow us to pursue activities and careers that most interest us, not just those we're mentally capable of, Haier said. We could master new languages in a few weeks, for example, or become brain surgeons. Smarter humans would also be healthier and longer-living, the scientists said, because they'd have a better grasp of what behavior leads to these attributes.
