The Tyranny of the Left

[midicon]

Perhaps it's as straight forward as skull 'total volume' .. but I bet that's overly simplistic.  I've never really dug into this before. I had heard that there is considerable variation between people in exactly how the brain "sits" in the brain pan, some have use more room, others are not so jam packed - and all that without significantly impacting mental function.  But I'm really only recounting what I may be misremembering.

My point is, that if there is a thicker corpus callosum and more connectivity between the halves then that might explain the difference between men and women. Not in an overt way but as a general bias that humans have picked up on and recognised over time.
I won't belabour this though. It's just something I've considered in the past and this thread reminded me.
