I don't know anything about helmets in particular. About a year ago I did some reading into risk compensation, the general theory that safety interventions cause people to take greater risks leading to worse outcomes than there would be without the intervention. There's plenty of theoretical speculation. It's attractive to a certain sort of contrarian who thinks they're smarter than domain experts. But any time anyone has actually collected real world data they haven't found the effect. Given it's been decades since the invention of the theory, and there's no evidence for it, at this point I think it's on the proponents to do some actual research. Until they do, I think we should disregard the speculation.
