That's right.
One major implications of this trend is that 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.
