The concept is quite simple: Explain your problem or challenge out loud to an inanimate object — such as a rubber ducky or teddy bear — or another person. In the process of explaining it out loud, you tend to clarify your thinking about it:
„It’s the talking that matters. Explaining your problem out loud is often enough to shake things loose in your brain, expose bad assumptions, and cause you to see things in a new way… Speaking out loud activates parts of your brain not accessed when you simply think. And even better, the act of explaining something gets you thinking in ways you might never have reached if you hadn’t tried to talk through it.“
