Child protective service workers are sent out into the community to determine when child abuse has occurred. Usually they make the right decisions, but sometimes they don’t. When they don’t, the public rages. “Off with their heads!” they imply as they chastise the workers either for not acting diligently enough on behalf of children OR for overstepping the bounds. The pdf that I’ve written for you looks at the issues that child abuse protection workers face from a statistical point of view. Perhaps after you read it, it may change your mind about the nature of their work, and the difficulties they face when trying to determine if a child is being abused or not.
