That was my conclusion, yes. Presuming Amy and Ben are ideologically wedded to their respective backfire beliefs: If the effect doesn't exist, Amy changes her mind, so won't try to Ben out of his disbelief. If the effect exists, the negative article will reinforce Amy's belief in it, but her positive argument will in turn only reinforce Ben's negative belief.
