I'll take a scientific study over a blog post, please.

Or to be less glib, the statistics he quotes seems very open for interpretation. "Stat #3: As more people buckled on helmets, brain injuries also increased". Need I say it? I think we're all pretty post hoc ergo propter hoc'd out at this point

Stat #3 might derive from the fact that a person is more likely to survive a crash with a helmet on. If someone dies because they aren't wearing a helmet it will be reported as a death, but if they almost die and the helmet prevents death but they receive some brain damage then it will be reported as a brain injury.
