Wonderful and very informative/helpful post.
If I may add: conclusions made by critical methods require validation by disinterested parties.
This means while we can and should employ critical methods, we cannot come to final conclusions alone. Critical thinking needs confirmation, controls, and checks. Without these our views are little more than opinion.
Confirmation by more than one disinterested party also prevents confirmation bias and promotes the inclusion of others and their unique gifts in producing valuable data.
