You can't explain your own thoughts and actions??? I'm sorry, but that's part of makes a valuable team mate or partner. This is not fundamentally human, this is trained behaviour. I am very well capable of expressing my thougts and explaining actions resulting from these thoughts.
Can you explain why you had a thought, however? And how many levels deep? Only as many as someone cares to ask, I'd wager.
You have developed the capability of explaining your actions as resulting from your thoughts, because there is someone on the other side who is ready to accept and evaluate your explanations.
Others have no such affordance, so their brains get trained in prejudices and superstitions indead. Even if an explanation of an action is given in good faith and accepted by the recipient, it can still be factually incorrect.
