Proper names are arbitrary. The fact that someone’s name is Baker doesn’t connect with anything about them. It’s random. But remembering that someone’s profession is a baker calls up a wealth of associations and connections in your mind. (Ooh, fresh bread.) So you’re much more likely to recall that someone works as a baker, but remembering that their name is Baker is a challenge. (There’s even an amusing study that showed people were more likely to block on the names Aladdin, Mary Poppins, and Pinocchio than with Grumpy, Snow White, and Scrooge. The latter are all descriptive.)
