to be wiser… than albert einstein. ever since we began measuring intelligence, our knowledge has increased. but are we really getting smarter?
Modern IQ tests for adults are set with 100 as the average score. Anything above this indicates higher-than-average intelligence; scores that are lower show below-average intelligence. (Scores outside this scale are possible in the case of children and adolescents, however, where the age is extrapolated.)
In a normal distribution, scores for intelligence, and a lack of it, rarely deviate from 100 by more than 60 points in either direction. The probability of an IQ above 170 is 1:653,000. At the outer ends of this bell curve, the lines taper off toward infinity. The chances of an IQ of 200 are 1:76 billion, and the world population is roughly 7.35 billion.
What would a person have to do to hit the magic score of 200 and thus have a level of super-intelligence that can still be measured? According to a model by psychologist Raymond Bernard Cattell, he would have to possess extraordinary (innate) fluid intelligence—a heightened ability to think logically and to learn quickly in new situations.

Predicted highest IQ:
Genetics research center BGI in Shenzhen, China, is currently sequencing the genomes (an organism’s complete set of DNA) of 2,000 super-brains. Once it’s determined which area of the brain houses fluid intelligence, prospective parents will be able to select the most intelligent zygotes (fertilized eggs) to create a super-baby during—and this will no doubt become an everyday phrase—pre-implantation genetic diagnosis, and give the baby its first present.
But there is also crystallized intelligence to consider. This, according to Cattell, is what allows us to acquire new skills, link up our acquired knowledge and store it all correctly. A working memory is fundamental, and, luckily, studies done by universities in New York and Hangzhou have proved that we can exercise ours like a muscle.The tighter that fluid and crystallized intelligence are interwoven, the higher the IQ. And the good news is that, unlike fluid intelligence, crystallized intelligence increases with age.
Mankind is becoming smarter by the day, not least because, in an ever-changing world, we are forced to make new associations, thus gaining in crystallized intelligence. This is known as the Flynn effect. So, what do researchers do to ensure the zero meridian stays where they want it to, in the middle at 100? They make IQ tests progressively more difficult, thereby forever pushing that magic score of 200 a little farther into the distance.
An IQ of 200? No problem, as long as a bright mind is quicker than the people who amend the tests. In any case, intelligence is relative; Albert Einstein’s IQ is thought to have been somewhere between 160 and 190, which puts the value of IQ scores into clear perspective.
