Ten commandments for critical thinking from Tom Chatfield

Tom Chatfield is an indefatigable British writer and thinker about games, creativity, technology and language. He has just written a guide to Critical Thinking for Sage (one of many compelling books). It's aimed at university students, but clarifying and useful for everyone faced with the daily barrage of themes, memes and dreams that pile over us from our mediasphere. The video above is an entertaining text-animation explaining his "ten commandments", the video below is a more conventional talk.
