SMS said:Most of the junk science regarding helmets relies on a disconnect with
logical thought. Invariably, the junk science (and not just as it
relates to bicycle helmets) ignores legitimate control-group studies
Like the ones that tell us that various discredited "healthcare"
procedures are a Really Good Idea...
Quoted message said:and looks solely at whole population studies without taking into account
the myriad of other factors that can affect the whole population.
It looks solely there because that's where you'll find the best
controlled data which is hit by the exact same factors. And anywhere
you do this, despite differences in myriads of other factors between the
different national population data sets, no positive change is seen is
serious head injuries among helmet wearing cyclists.
Quoted message said:studies are superficially impressive, including seemingly precise
statistical calculations. They appear "scientific" but they don't meet
the fundamental criteria for science, rather they try to look at various
variables, and create inferences that are not based on the data.
It's very straightforward science. There is no positive change so we
suspect no positive effect. OTOH the "legitimate control-group studies"
can usually be laughed out of court for the shocking attempts at science
they represent, yet people are still quoting them.
Quoted message said:A statement such as "cycling injuries/deaths went up after a helmet law
was passed, so helmets are not necessary" shows a lack of understanding
of correlation versus causation that a more educated person would not
fall for.
Quite so, but that's a straw man because nobody serious about a helmet
sceptic position with a Clue is actually /saying/ such a thing.
Quoted message said:I.e. "I must say I've enjoyed my cycling a lot more since I
found out how necessary they aren't and stopped wearing one."
Is not saying what you suggest above at all. I used to consider they
were necessary, and always wore one. I have since changed my mind and
no longer wear one on the road. They are clearly /not/ necessary or
cycling would not have been possible. I enjoy my cycling now more than
when I always wore a helmet. These are all simple statements of fact
and nothing to do with correlation and causation.
Quoted message said:I'm not
sure if this poster was being sarcastic and trolling, or if he really
has fallen for the junk science.
You have fallen into the trap of reading more into a simple sentence
than was there in the first place. I stated some simple facts and you
tried to twist them into "junk science" for the purpose of making a
straw man.
