It's happened to all of us: We're in the shower, or on a walk, and boom — a big idea or a brilliant solution appears out of nowhere. These sorts of insights often seem to arise without explanation.

There's a tradition around many Thanksgiving dinner tables that's as consistent as stuffing and pumpkin pie: the family stories that get told year after year. Sometimes these stories are funny; sometimes they make us roll our eyes. No matter how we feel about these tales, we rarely pause to consider how they shape who we are and how we view the world. This week, we talk to psychologist Robyn Fivush about the profound impact that family stories can have on our lives.

She explores how being of two minds changes the way we think, and how it changes the way others see us.
