On the argument side, this can be termed brainstorming, discussion, argument; depends on your point of view and communication preferences. If nothing else, our political leaders and media pundits, and their constant squabbles, reinforce this reticence to embrace failure or regard arguments as a beneficial mechanism to getting things done.
But research shows these mechanisms can actually be very powerful tools for developing critical thinking skills, learning in general, and getting things done. Two recent blog articles discuss these issues in terms far more eloquent (and researched) than I could even attempt:
- The Importance of Thinking about Thinking
- Make Meetings More Productive by Arguing
- (addendum edit) Set Sail for Fail video (ALA 2010 Unconference session)
