Kinda like a motorcyclist drives slower, and is less likely to take risks, without a helmet. It would seem as though it's a trade out. Fewer incidences, but more severe when they occur.

Quite possible but I would think a good study of Rugby and Football would yield some valuable information and maybe on the whole helmets will be found to be valuable or counterproductive. Both sports have similar types of contact so it would seem going back through the archives of player history some valuable data could be gleaned.
