Neat theory but it's too simple, IMO.
There is *over*-caution immediately after giving up the
helmet because your head feels very different so you can't
stop thinking about how "vulnerable" you are. But, IME, that
does evaporate after you get used to the way your head feels
and behaviour then normalises.
But going back to how it is when wearing a helmet...........
I've always had some trouble with the risk compensation
theory with bicycle helmets (on-road at least) because, at
least with well-experienced or informed cyclists*, there are
plenty of fears to keep you in check *before* worrying about
hitting your head. I don't want to fall or crash because I'm
quite likely to badly graze my arms and legs, sprain a wrist
and wreck my bike. I don't want any of those things
happening at all! So I don't want to crash at all. Head
protection is very much a secondary consideration, in fact
so much so that I don't bother wearing one any more for
normal cycling**.
Actually I did once hit my head in a cycling accident
whilst not wearing a helmet, but the experience only
reinforces my view as the head injury didn't actually cause
me any problems (apart from forgetting the circumstances of
the crash). It was the damage to my back and bike that put
me out of action for a long time. Of course the head injury
could have been worse if the impact was worse, but as we
know, bicycle helmets can't actually provide much
protection anyway. The experience also made me modify my
behaviour, considerably, but I fear that I'm slowly
returning to my old ways.
Still, knowing my head is better protected wouldn't make me
want to risk busting my arms and legs and bike any more. But
perhaps this does not apply to people who regard those sort
of injuries as trivial, so Helmet Risk Compensation Theory
probably apply to them.
* people who know that other injuries are more common than
head injuries.
** I did for a year or so: got fed up with getting
overheated (vents only work when moving, and moving at a
good speed). I don't believe I took any more risks when I
wore one for regular cycling. However, I would wear one
again if I deliberately wanted to take more risks for more
special kinds of cycling, eg. for racing or chain gang type
riding or hard-core off-roading.
