Surely pro cycling is an almost ideal control for determining exactly how effective helmets are. Take the years that cyclists were going modern speeds but before the helmet rule. Say, 1970 till 2003 (or 1960?). How many pro cyclists got major head injuries in that time? How many pro cyclists have had major head injuries averted due to helmet use since that time?
My general feeling is that pro cyclists go down often enough that helmets make more sense in the peleton than for the general population. Of course I've never actually seen any evidence.
As a utility cyclist, I find a helmet too inconvenient, and I'm not convinced they offer enough protection to be worthwhile. This doesn't stop me from using bright lights, wearing bright and reflective clothing (especially at night), choosing components for safety (studded tires for winter riding, quality brakes..) and carefully maintaining my bike. All of those things have costs too (both to convenience and in $$$), but they all seem much more useful than a helmet to me.
Similarly, I don't ride with a bell. My voice is far more effective than any bell, and I use my voice to communicate with other road/path users several times on every ride.

So lets take the opposite argument to its logical extreme.
Helmets on cyclists save lives
therefore they are mandatory.
Helmets, five point safety restraints and limiting maximum speed to 90kms per hour will save countless vehicle operators lives.
therefore it should be mandatory.
HOWEVER. This is not the case, simply because a amount of death and injury on the roads is regarded as unavoidable so as to maintain a standard of comfort and convenience for users and a degree of freedom for manufacturers.
Mandatory helmet laws are a excuse of governments to take the focus from real road safety and efforts to get people out of cars and onto bikes.
The only thing that makes cycling safer is more cyclists and right now compulsory helmets are not encouraging this.
This. 1000x this!!!
I mean just look at the seat belt example. When lap belts first came out, people were told to use them, they'll save your life. In the end, it isn't clear exactly, but lap belts may have caused more injury than they prevented. Once the defective design was fixed by adding shoulder restraint, seat belts became very obviously beneficial, and I'd never drive without wearing one. (edit: Now, of course, there are even better seat belt designs -- 5 point restraints as found in race cars -- but nobody suggests those for cars, because they'd be impossibly inconvenient.)
It isn't nearly as simple a question as most people think [strike]though[/strike](ed).
