Before you even start analysing the fuzzy thinking or uncritical thinking of others, it is best to examine one’s own motivations and biases. To this end, there are two classics one must read first: – The MeatBall Wiki’s “AssumeGoodFaith” is a masterpiece “How To” for Internet based discussion and argumentation.

A Code of Conduct for Effective Rational Discussion” is the best set of fallacy avoidance principles that I know.

New logic and argumentation software from the makers of Sciral Consistency
“Flying Logic is a highly visual, easy to use software application that does for reasoning what spreadsheets do for numbers. Just as you would not do detailed financial projections in your head, you need Flying Logic for all nontrivial planning and reasoning endeavors.”
TruthMapping is a tool that addresses the most common problems in argumentation. It prevents digression by making the argument the context which can not be escaped; the information flow is always toward the argument unlike standard methods such as conversation, message boards and e-mail. It saves you time because others can not bury your contribution through repetitive posting. It is a content-rich view of a topic because only the true disagreements are visible by default.  [Excellent]

  1. Michael Meadon

    This is an excellent resource! A couple of things (in no particular order):

    1. I’m no so sure about Buzan and de Bono… they’re both borderline cranks IMHO.

    2. The link to the critical thinking mini-guide has changed, it’s now here:

    3. Overcoming bias ( is an absolutely superb critical thinking blog.

    4. Mistakes Were Made (but not by me) by Tavris & Aronson is the best critical thinking book I’ve read in quite a while — check it out.

    5. I rather disliked Wheen’s How Mumbo-Jumbo Conquered the World. Check out my review:

    6. van Gelder has a blog ( and an audio podcast was made of one of his critical thinking courses, but I can’t seem to find it now.

    7. There are lots and lots of great skeptical blogs, but my favs: Bad Science, NeuroLogica & Science-Based Medicine.

    and, finally,

    8. I can’t believe you didn’t mention Fads and Fallacies in the Name of Science by Martin Gardner! 🙂

    Thanks Michael. I have updated the broken links and added the weblogs and books you recommended.

    This page needs to be thouroughly updated and restructured. It started out as a wiki page, then when I got sick of maintaining a copy of MediaWiki just for this page, so I moved it onto the blog.

    There is plenty of junk on here now and the resources are badly described. This year I will make it a goal to tidy it up properly.

    Thanks for the input and suggestions!
