Says who?
It's a web-site that is produced and moderated by internationally respected academics and experts. You simply don't like it because it doesn't agree with your views.
But perhaps you can amuse enlighten us by giving us your credentials to comment on whether or not they know their stuff?
From their website:
Whilst cyclehelmets.org strives to be objective in its selection of information for presentation, there is more helmet-sceptic material on this web site than that supportive of helmets. This is in part a matter of copyright (we provide references to journals but cannot generally give direct access), but largely because there is a far wider range of arguments and sources that cast doubt upon one or more aspects of helmet efficacy. cyclehelmets.org is not helmet-sceptic on principle, but because pro-helmet predictions are so often contradicted by real-world experience.
I hadn't realised that copyright was the deciding argument in helmet usage!
Most of the research they quote is from the 1980s to 90s
"Dorsch, 1987 -90% fatalities
Thompson, Rivara, Thompson, 1989 -85% head injuries, -88% brain injuries
Wasserman, 1990 -29% concussions, -82% skull fractures
McDermott, 1993 -39% head injuries,
but no significant reduction for adults
Thompson, Rivara, Thompson, 1996 -69% head injuries, -65% brain injuries"
If I used references like these in an Essay it would fail!
And their review of Elvic's paper is WRONG In places.
For example they say Elvic states
Elvik notes that while, on the one hand, studies have predicted large benefits from the use of cycle helmets, large increases in helmet use brought about by helmet laws have not always shown a clear decline in head injuries to cyclists. This could be due to selective recruitment – that the most cautious and safety-minded cyclists with a lower rate of accident involvement are the first to start wearing helmets – or because of behavioural adaptation (or risk compensation), whereby helmeted cyclists feel safer and thereby ride less safely
While the actual article states
Another possible reason why the aggregate effects of bicycle helmets could be smaller than expected on the basis of individ- ual effects is behavioural adaptation. Once helmeted, cyclists might feel better protected and adopt more risky riding behaviour. While this cannot be ruled out, there is no direct evidence for it and performing a convincing study of such behavioural adaptation would be very difficult.
Lazy, lazy stuff. GCSE level at best I'm afraid....but if it makes you happy go ahead.
My advice ...stop using Google. if you don't have access to a wide range of journals try Google scholar. Less crap.
Edit...changed quote for correct one...I'm as lazy as that website!
