Fascinating George, you present compelling evidence to suggest that there may be a correlation between a certain type of giftedness amongst left handers.
My eldest son is left handed and I have witnessed how he has had to adapt from learning how to tie his shoe laces, to learning how to write in our right hand world. I wonder if being in the minority is also a factor causing left handed people to build a type of resilience that transfers to particular strengths and activities.
I imagine because there are so many factors we need more conclusive studies to better understand where there is correlation and causation.
As always, great write.
