@smalllife. I think it could be partly explained by the famine/binge construct, but I think it is subtly different. I guess thats the trouble with all these psychological constructs/views, there's often overlap or different ways of looking at the same thing. It might also be partly akin to ones "inner child", another popular idea.
Lots of people are S (sensate) dominant ie concerned with short term spontaneous concrete satisfaction of the senses.....that's why they don't get MMM. But its their dominant preference and they are good at it and practice it a lot. For IN-Js its the least preferred way of operating, often deeply hidden in the psyche and if used, IN-J's don't have much skill with it and can go overboard.
You made me think Smallife..is it always associated with deprivation?... initially I said no, since I could think of times where I've flipped into it without any apparent "deprivation". eg the weekend I decided spontaneously we would jump into animal rescue and rescue some guinea pigs . There was no deprivation involved....the opportunity came up and on the spot I decided it would be fun, a novel experience completely different to our usual weekend, and the activity felt slightly risky and dangerous, since we had to perform the rescue. If i'm honest it was not about the noble act of rescuing, but about a fun novel spur of the moment experience.
So no prior "deprivation" except that the INTJ personality tends to over think, plan, and generally be cautious and maybe the spontaneous, for the moment experience represents the binge or "break out". In this instance I don't regret doing the rescue, but I look back on it with slight amusement, recognising its not my thing, and wondering "what was I thinking?"..
