How I think Rubber Ducking works for me: Explaining things to others - imaginary or not - engages the parts of my brain imagining how they will receive and understand it. This is primarily so I can phrase it in a way other people can understand. But that imagined model of other minds is often smart enough to imagine what they would answer. Which I guess means my "social brain" is smarter than my "thinking" brain in some ways. Don't know how universal that is. My brain tends to be an outlier.
