It’s “adaptive speed”. The broadest associations, in the largest brain volume, with the least information, in the shortest time, with the least repetition.

Working Memory augments it.
It’s basically an economy: associating neurons get fed. Fed neurons connect, roadways are frictions. obstacles on roadways increase friction.
The more grey matter, the more hierarchically organized, the more compute, the more white matter the more transportation. Absence of Friction is the best way to think about the problem of producing intelligence (less genetic load), just as trust reduces friction in our real world economy.
