Right, that makes sense, our brain will do a quick black box judgment (some may call it system 1), and then rational process only works to justify that or explain the black box, assuming that black box is always correct (depending on the person and how much they trust their black box or system 1).

So system 2 is "hallucinating" the best justification for system 1.

And usually system 2 will do it only when it's required to justify it for anyone else.
