Joshua Foer Rarely Quotations

Photographic memory is often confused with another bizarre - but real - perceptual phenomenon called eidetic memory, which occurs in between 2 and 15 percent of children and very rarely in adults. An eidetic image is essentially a vivid afterimage that lingers in the mind's eye for up to a few minutes before fading away.

When I climb into my car, I enter my destination into a GPS device, whose spatial memory supplants my own. I have photographs to store the images I want to remember, books to store knowledge and now, thanks to Google, I rarely have to remember anything more than the right set of search terms to access humankind's collective memory.
