Bicycling has never been a major source of serious traumatic brain
injury (TBI). On a nationwide basis, bicycling's contribution to TBI
counts is low enough to be off most "causes" charts. Bicycling causes
fewer then 1% of U.S. TBI deaths, far fewer than pedestrian travel, and
far fewer on a "per mile" basis. And historic data over the years shows
quite clearly that bicycle helmets are not preventing either fatalities
or concussions.

You could prove that helmets don't always prevent head injuries, but
not that they don't sometimes do it. Proving a negative is difficult
task.

Correct.  At worst I can say "will not help on average" but I won't be
able to say "will never help and never hurt" or "will sometimes help and
sometimes hurt really bad".

But what should the consequences be for me: if it sometimes helps and
sometimes hurts, how should I ensure it helps me instead of hurting me?
