I wonder what the correlation of handwriting is with right brainness. I think that if someone is more in-touch with their right brain (heavy right brainness if you want to get technical 
) than they have neater handwriting. I think this goes well with some theories that I have read because being able to use both hands (ambidextrous) is more prevalent amoung (intelligient) people. Of course I am just remembering these theories/facts out of my memory which is of course inherently unreliable since every read is a write.
