Downvotes should contribute positively to the knowledge discovery, creation and development process by giving fellow researchers feedback information on the perceived negatives in an answer. In order to prevent glib, flippant and otherwise unreasoned downvotes and so ensure that a reasoned contribution is being made, the downvote protocols should therefore include navigating a process of researcher feedback and independent confirmation before being registered as a downvote.
Recommended Two-Step Downvote Process:
a, first select the explicit reason for downvote from a menu of options including an open-ended 'other reason' (this will also serve to give researcher being downvoted reasoned feedback for the downvote)
b. at a minimum downvotes should only be registered after a second confirmatory downvote action by an independent researcher which supports the reason selected / given by 'a.'
