Blame the guitar man
I've read all 200+ pages now (I feel one really should if one is to be taken seriously when commenting) and I fear I cannot add anything to the debate that hasn't already been said, bar one thing, namely:
It's one more person convinced by the arguments within to remove their helmet.
I *feel* safer with one however this has I believe been shown to be erroneous in this thread.
The only evidence I have been swayed by has been on the side that says for whatever reason wearing a helmet isn't safer and may in fact be less safe than not wearing one (Aus/NZ/Can data being the prime source). I can find no evidence here or elsewhere to the contrary (the oft quoted 'it's obvious innit' 'saved my life...' isn't evidence).
Once I have dispensed with the personal safety aspect, the only nagging doubt that remains is the one about 'victim blaming', I am still somewhat concerned about the consequences of this should I ever become a victim.
It seems to me that on a personal level I could theoretically lose compensation in court, be berated by the public and more worryingly the police and health professionals for not wearing one should the worst occur. Being berated I can live with, losing compensation or a court case is a concern. This worry would be obviated by my continuing to wear one, albeit at an increased risk of being injured in the first place.
Against this I must balance the increased risk of injury and also, crucially, the fact that the more people that wear helmets the greater the perception of cycling being viewed as dangerous and thence the commensurate increase in risks brought about by both less cyclists and an increased chance of compulsion (both of which make *my* cycling more dangerous).
At the end of the day, for me (personal choice, informed decision), the risk of being a blamed victim is insufficient - the helmet goes.
