Part of Mental reference frames of concepts have at most seven "features"? and The reference frames of project alphas.

That is, brain does not store information in “pictures” like this, where concepts are connected horizontally on the same “field”:


At least, not in my mind. At best, there are many proto-frames with just one feature, but all these frames are weakly connected to each other and therefore don't aid thinking (again, this is according to my reflective feeling only). It might be that I didn't acquire the necessary mental tools/habits to track such "horizontal" relationships in the reference frames. Alternatively, I may belong to a part of the population that lacks such an ability. Finally, this might be universal for all human minds.
