Given the choice between two babysitters, we’re more likely to trust a babysitter with a little experience from the neighborhood than one with lots of experience from far away. We wouldn’t trust someone from the outside because we don’t know anything about them, we say. The reality is, we don’t know anything about the local babysitter either, beyond the fact that she’s from the neighborhood. In this case, we trust familiarity over experience with something quite important—the safety of our children.
