The Illusion of Explanatory Depth

When something feels fluent, you assume you understand it really well. There's a phenomenon known as the illusion of explanatory depth. And one reason we think this happens is because people ask themselves the wrong question. So when I say how well can you explain how a bicycle works, instead of thinking do I know how the train and how the pedals work together, you ask yourself a different question which comes very easily. Those answers give you the sense that you understand the true question better than you actually do.
