mgeorge is spot-on...rolling to left is preferable (in most planes at least) due to 1) torque/p-factor and 2) leverage with your arm. Just try holding an imaginary stick with your right hand, and pushing it all the way left, and then all the way right. It's much more natural to go left.
Here's an explanation from the book
Sierra Hotel, written by the current USAF Historian and a former F-4 and F-15 pilot (Lucky Anderegg):
Quote:
Most pilots like to turn left because it is easier to push the stick left than it is to pull it right. Try this yourself. While sitting in a chair, put your right forearm on your right thigh with your fist between your knees as though you were holding a fighter stick. Now hold your right fist firmly in your left hand and push with your right fist to the left against the resistance of your left hand, then reverse it and pull with your right fist to the right. It takes less muscle to push than to pull. That's why, if at all possible, landing patterns, instrument patterns, and gunnery practice patterns are set up around left turns.
