Sparks is an open forum for discussion and contributions not only from NORC's Experts but from its readers as well. On Sparks, we welcome your insights and opinions, with several simple requests: be thoughtful, respectful and please add to the conversation. Comments are moderated by NORC staff and we don't tolerate inappropriate contributions. External non-NORC links on this blog do not constitute endorsements. That said, SPARKS is about sharing information with as many people as possible and our policy is to accept most, if not all comments.
