Global average IQ increased 30 points over the past 100 years

Global average IQ increased 30 points over the past 100 years!

In times of Donald Trump – who would have thought that one could become president of the United States without even being able to form a coherent sentence or thought – and other science deniying politicians it may be hard to believe, but over the past 100 years the mean (statistical jargon for what is commonly referred to as average) fullscale IQ has increased by 30 points. Fullscale IQ hereby refers to the general IQ of a person as opposed to the specific IQ in a certain area like mathematics for example.

Put differently:” [….] an average individual alive today would have an IQ of 130 by the standards of 1910, making them more intelligent than 98% of the population at that time. Equivalently, an individual alive in 1910 would have an IQ of 70 by today’s standards, a score that would be low enough to be considered intellectually disabled in the modern world.” [Mohamed Nagdy and Max Roser (2016) – ‘Intelligence’.
