Cool, didn't know there was a name, Dual Process Theory. It's how I have come to understand consciousness myself in observing how humans operate.

Habituation is common indeed, even akin to reverse hallucination, where we stop feeling the socks on our feet, chair we are sitting in, foot on floor, pants on, etc. Lots of habits form and we run them automatically, unconsciously, unthinkingly. I refer to conscious thought as thinking proper (active), while unconscious thoughts as not thinking proper (passive).
