:::There are no WP:COI issues; as I said, I have no real-life connection to ISCID.  Per WP:NPOV, Langan's work should not be asserted as being the truth, but neutrally presented.  That's what I've tried to do, taking care to use frequent qualifiers (e.g. "According to Langan", "Langan argues that", "describes what he sees as") and footnoted citations.  I welcome specific feedback on my edits and suggestions for improvement.  I'm trying to engage constructively, and hope we can work together to improve the articles in question.
