Still, for the first twenty-five years of my life, the concept of intelligence was intimately connected to broad-spectrum memory. If I was having an argument with a much older person about the 1970 Kent State shootings, I’d generally have to defer to her analysis, based on the justifiable fact that she was alive when it occurred and I was not. My only alternative was to read a bunch of books (or maybe watch a documentary) about the shooting and consciously retain whatever I learned from that research, since I wouldn’t be able to easily access the data again.
