RDD works because most of the people really don’t understand what they don’t understand without a direct linear thinking about the problem. They have this blob in their head that creates an illusion of knowledge.

I have the same thing. Every time I start thinking “big” I need to consciously stop myself and ask “what do you not know?”/“what needs to be measured?” Instead of continuing making assumptions.

You don’t need to speak to a duck to do that though. Speech has got nothing to do with your ego/laziness that makes you believe there’s nothing to be done and everything can be solved by thinking.
