Maybe the issue is that intelligence itself is inscrutable? When you are asked why you did something, and provide an explanation, is your explanation accurate?

Maybe the issue is that intelligence itself is inscrutable? When you are asked why you did something, and provide an explanation, is your explanation accurate? Do you really have access to this information? Or did you think, "I must have done X because of Y"? What about a simpler question: "How did you do X"? When I answer this, I often cannot provide an answer, and I have to redo X and observe what I'm doing.
