one thing niplav culture started doing very early was to group niplavs into group of 2-4 people who would form a worker/research unit (friendship encouraged, but romance discouraged). because of high agreeability, these units can be *very* stable, and are especially useful in trying to understand & solve difficult problems, often by one niplav being the babble and the other being the prune. this also has the advantage that for a niplav, intellectual work is around three times as fun together
mainly because there is some very quick feedback mechanism that bores into weak points of understanding or sloppy parts of models/proofs, where a single niplav would just shrug and give up early.
an optimal session is two niplavs at a whiteboard, either both thinking, or one explaining an idea to the other, and a third sitting at a laptop in the background and writing down the ideas as they're developed (and only sometimes asking questions for clarification).
there has been a large amount of experimentation to find psychological characteristics of niplavs that are especially conducive for forming these kinds of groups or pairs, and a large portion of the teenage years of a niplav is spent in various different groups to find an especially well-functioning one.
these groups also work very well as ways of quickly organizing commitments, e.g. for meditation, exercise, artistic projects etc.
this is less of a problem than one might suspect, because niplavs are generally easily made enthusiastic about most topics, niplavs are agreeable and willing to try the stuff other niplavs think are cool, motivated to stay in their group because they have grooved in a very strong rhythm, more capable of understanding why something is cool (because of short inferential distances), and the groups are carefully chosen to maximize potential common interests.
one disadvantage is the huge variety of interests a niplav can have, it is often not possible to find a pair/group where every niplav is at the same time interested in bebop, type theory, bouldering and forecasting. usually, this is solved by having one primary group that is broadly intellectual, and then side-projects, with elaborate rules about how to deal with these side-groups becoming more important than the main group.
