What is critical thinking?
Nobody said it better than
Francis Bacon, back in 1605:
For myself, I found that I was fitted for nothing so well as for the

resemblances of things … and at the same time steady enough to fix and

to seek, patience to doubt, fondness to meditate, slowness to assert,
readiness to consider, carefulness to dispose and set in order; and as being
a man that neither affects what is new nor admires what is old, and that
hates every kind of imposture.
A shorter version is the art of being right.
Or, more prosaically: critical thinking is the skillful application of

A classic book in the better thinking/better writing genre is Barbara Minto's The Pyramid Principle. It would be the closest thing to a how-to-think Bible in business and management consulting circles. Unfortunately it seems there are precious few online resources on the Minto approach; if you want the good oil, you have to buy the book (or pay dearly to attend a Minto seminar).

Wicked stuff. "Regular postings based on fallacies covered in our book
Humbug! ... Using a seamless combination of both passion and restraint, we
expose erroneous thinking with irony, whimsy, sarcasm, satire, caricature, "distortature"

carefully written commentary on fallacies. Humbug! the blog is less
considered, more spontaneous and at times more outrageous. No poppy is too
short to be lopped." [16 Feb 06]
