Those of us who promote critical thinking when using Internet resources have favorite “go to” examples; Tree Octopus. I wonder if it would not be more productive to use online pronouncements related to political issues. Factcheck.org offers a variety of examples. I suppose the orientation of this collection would be problematic, but I find these examples more supportive of the charge to think critically than does the fabricated story of a tree octopus.
