In the interest of experimentation, I ask that you look away until you have finished wearing rings for a day or so. Of course if it is painful, take them off immediately.
Are you done? OK LOOK:

You have 50% chance of putting rings with correct polarity even with advice people gave above. Both configurations will pass the tests -- but which one is the right one, can you tell? If it turns out you put the rings on "wrong" and still felt good or even no effect, this supports theory that polarity doesn't matter. Only your brain-polarity matters. If you get bad results, it could be your brain is fossilizing, and is unable to flip polarities of your body to match the rings. Therefore, I do not recommend flipping polarity on people with alzheimer's etc...
I used to think polarity mattered a lot, but then I found out that pickup devices vary in their pole configurations. I tried wearing the pickups 'right' side up, upside down, etc... It never harmed me, it is only more or less comfortable. This week I'm going to try an experiment and grip the pickups instead of strapping them, because this is the position you have with a guitar -- maybe the ROCK WILL FLOW BETTER THIS WAY??
