FIML is hard to do at first because it violates, or seems to violate, a basic language instinct to not interrupt another speaker or question them too closely.
FIML gets around this instinct by having partners make a prior agreement to interrupt (or break into) a conversation and question each other closely, specifically to ask their partner to divulge the contents of their working memory and then (often) divulge their own.
FIML establishes a new human skill. The ability to do the above quickly and easily, and without undue emotion.
It will feel a bit weird at first to learn and exercise this skill, but after a few dozens iterations it will become fairly easy and eventually become second nature.
I believe FIML has never been discovered and this region of interpersonal language and communication has never been properly explored due to the strong but superficial instinct against it mentioned above. I would also speculate that this instinct is a significant contributing factor to hierarchical social structures and the psychologies that derive from them. In this respect, the psychologies of virtually all people everywhere are deeply steeped in the mores, taboos, and sensibilities that attend to and revolve around the instinct to hold your tongue when you most need to use it.
As post-modern humans on the verge of an earth-shaking AI singularity, it is past time to overcome this part of our primitive nature. ABN
