Eye dominance

There is actually a whole segment of Sports Medicine dedicated to this. When I was on the CU Freeride program a rep came in to talk about it. Its really interesting and factors in how your brain processes visual info under stress such as a dangerous line or comp setting and how the mismatch between your brain processing and your eyes can cause mistakes. Here is something similar, its actually really interesting:

On a side note, I used to longboard a lot so I ride rails left foot forward but spin left naturally. It was actually easier for me to ride into some rails switch because then I would spin the right way for my feet.

I have quite significantly different vision between my eyes where my left is far worse than my right but I still spin left. I've always wondered if it's making my life difficult for spins but never thought too much about it. Changing now seems too difficult having been spinning left for 15 years on skis and rollerblades.

I tried to find correlations between a few things to find someones normal spin direction. Left/right handed, strong leg, skateboard stance... so far I have found no real correlation. I keep finding people that break the hypothesis every time.
