Convergence time...  It's odd that we don't ever hear about that when
science-popularizers are chortling that "women use both halves of
their brains and men don't".  (to accomplish specific tasks, but that
usually goes unsaid)

But anyways, local specialization makes me doubt the theory that large
brain = large convergence time for tasks of interest.
