You wouldn’t expect that a military web site would be a great resource for the peace-loving conflict resolution crowd, but you’d be wrong.
Air Force University maintains on its web site one of the most comprehensive lists of creativity, problem-solving, critical thinking, and decision-making resources I think I’ve ever encountered. Find links to information on everything from emotional intelligence to creativity and innovation to fallacies in logic.

I also highly recommend the Air Force’s Negotiation Center of Excellence (http://negotiation.au.af.mil/) which has resources on international, crisis, labor and job related, acquisition & contracts, and environmental negotiation, in addition to alternative dispute resolution, consensus building, mediation and facilitation.
Tom, thanks for the reminder and for sharing that link!
