How Intelligence Shifts With Age - WSJ: "One form of wisdom, the ability to guess people’s internal states from very little information, is as useful around the kitchen table at it is in the boardroom, and “the difference between a 20-year-old and a 40-year-old is just huge,” Dr. Hartshorne said.
The gains don’t end there. As our hair becomes silver (and sometimes falls out), our vocabularies continue to grow, peaking as late as age 70, said Dr. Hartshorne, adding that 20 years ago tests of vocabulary showed that it crested much earlier, at age 50. “Given the way we’ve chosen to define intelligence, people are getting smarter,” he said.
This is an encouraging sign. If humans continue to learn into their seventh decade, then at least one platitude is true. You can teach an old dog new tricks."
