Tha`ts right IMHO. The believer par excelence is the one that don not know that he believe, and do not know that there are parts of reality that he reject. This is the primitive sense of religious belief. Medievals believed this way, because nothing challenged his faith.

Men tend to reject uncertainties and adopt a closed set of truths, and reject to think in anytihing that challenges it. these kind of believers will kill you or socially kill you if they can not kill you. They may call you infidel or unscientific. they can call themselves right men, Truth believers or Peer Reviewers.
