Oh absolutely. “think again” vs “adjust” is a decision. Is there a problem with the plan that requires adjustment, or is there a problem with one of the basic assumptions that led up to the plan that requires scrapping the plan entirely because a base foundation was incorrect?
You can have a marvelous hypothesis that that measures and tests perfectly and leads to a wonderful conclusion… only to find out later that the hypothesis ITSELF had fundamental flaws in it because the underlying assumptions were wrong.
What’s marvelous about the double-loop, is *nothing* is sacred to it, there’s nothing that is forbidden to be revisited and checked. It’s also more frightening because you could be going against a lot of received wisdom in the process that could _also_ end up being found wrong in the process. Paradigm shifts is a fancy term for it.
For example, what if observation and experience turn out to be unreliable in a particular circumstance? What if empiricism is the assumption that turns out to be mistaken? In short, there’s no sacred cows, as it’s all about the process, not the content.
