A little knowledge can be a dangerous thing... it can lean you to an
entirely false conclusion.
Quoted message said:point is that there are studies and data is collected continuosly.
if you look at studies based on continual data gathering (typically
whole population studies, as governments collect and collate road
traffic accident data) then you get to see the picture that helmets
don't appear to make any clear difference to serious head injuries.
Quoted message said:most of us believe that helmets do gives us an edge in a very dangerous
world--the streets
For some values of "most": in many countries, including those with the
lowest serious head injury rates, helmet wearing amongst
transportational cyclists is very much in the minority.
And what "most of us believe" isn't necessarily what happens, and if you
look at the whole population studies you can see pretty good evidence
that a helmet doesn't actually increase your chances. if it did, they'd
be making a clear dent in the figures, but they don't.
I used to believe a helmet gave me an edge, but I was challenged to look
at the research closely (not just a few selected abstracts, but the
whole papers, which is relatively easy as I've got a medical research
library a few minutes from my desk with full access to many publications
the general public can only get abstracts for). I went in to prove what
an idiot the guy challenging me was, but came out realising the evidence
I had counted on until then was at best half baked.
There is no clear evidence I've seen that helmets really do give an edge
on the streets, and I've looked quite hard. That is why I stopped
wearing one.
