Now what evidence do you have about helmets protecting against dented
skulls or brain injuries?


I have an idea for an experiment. Go outside and have someone hold a brick
about 2 feet over your bare head and have him drop it. Observe the pain and
damage (assuming you're still conscious). Then try the same experiment on
your friend, but have him wear a cycling helmet. If he laughs at you, you
may be able to infer from this, experimentally, that he thought it was not
necessary to run the experiment to know that you would end up with a damaged
head and he wouldn't.

If you are unable to apply the knowledge gained from this experiment to
real-life, I would submit that it's not more experiments that you're
actually in need of.

Well, that's the problem, isn't it? Tough to run a controlled study of
this type in real-life conditions.
Why someone would even try to suggest that helmets don't save lives
because there are no controlled studies to prove they do says more about
these people than it does about helmets.
I've heard the same arguments from people who don't wear seatbelts in
cars. I thought they made what could be valid points--until I spent a
year covering head/neck trauma during my residency.
