Mohammad Khan, an immigrant from Bangladesh, owns a diner with a giant American flag painted on the building. "Joe Six-Pack is people just like me — work every day, pay their taxes."

"When I think Joe Six-Pack, I think of the hunter and his gun and his dog, and that's a definite white man out in the countryside," says Blanche Hake, a retired teacher who is white.

Margie Orr, who's black, says "The others are lazy. They don't work as hard, so that's where the Joe Six-Pack comes in. He's a hard-working white man."

When someone hears the name “Nora the newbie” or “Joe Helpdesk” they draw on past experience to imagine someone they know, or project the context of other times they’ve used the term into your persona. As a result, when a group work together to design something for such a persona (whether it's a Web site or tax policy), they each have different (often unvoiced) assumptions about who this person is and what their needs are. By using a more realistic persona name, and describing the behavioral characteristics you want to emphasize, you make it easier for everyone in the group to imagine the same person.
