Benjamin Mitchell presents ideas using Chris Argyris thinking on double-loop learning. “Double-loop learning occurs when error is detected and corrected in ways that involve the modification of an organization’s underlying norms, policies and objectives.”
Single loop learning is basically to just try again using the same understanding, thinking and tactics. It is understood that the results were not what was desired so we will try again, but the supporting system is not seen as the reason results were not the desired results. Double loop learning is when the result leads to questioning the system and attempting to adjust the system and make changes and experiment to learn to be able to create systems that get better results.
Argyris: people will blame others and the system when their actions seem to differ from their espoused proper actions. (I see this as similar to the idea of revealed preference versus stated preference: revealed actions versus stated actions – John)
