I actually wear full body armor. All the time. You know, just incase I get stabbed.

But I agree that the more cyclists there are the safer we will tend to be. Unfortunately, the evidence suggests that making people wear helmets discourages them from cycling. If the figures you reported have to do with serious injuries, and helmets are not designed or proven to help in the case of serious injuries, then of course the figures regarding serious injuries probably reflect that. Duh. No matter what people hope. What people hope for and what helmets are designed to do are two completely separate issues. I've seen the same studies you have whick show that making people wear helmets discourage people from riding bikes and I do not doubt the veracity of such studies. But what about most of the world where people are not made to wear helmets, where helmet use is optional? If the majority of helmet wearers are as deluded as the bare-head brigade think, that these styrofoam hats project an invisible safety while riding forcefield, then perhaps there are people riding a bike with a helmet for the wrong reasons who might otherwise not be riding a bike... See, cycling is a safe activity. Even with a helmet. |

Perhaps you'd like to cite a particular study that you believe proves their effectiveness? Then it would be possible to have an actual debate, as opposed to dismissing you as a troll.

There are plenty of government, insurance institutes, medical world studies to prove otherwise. Most of the reasons helmets fail is due to improper fit and adjustment. And sure helmets can't protect the head at all times, no one is saying that, but they do protect. Motorcycle helmets fail too, does that mean MC riders should throw away their helmets? Race car drivers wear helmets but they too sometimes fail, does that mean they should throw away their helmets? Dude, get real. Even if by some scientific study that the entire world falls in step with says that bicycle helmets are only effective 5% of the time isn't that 5% better then 0% from not wearing a helmet? Of course studies prove that it's a lot more then 5%, but I was just using a obscenely low rate to make a point.

I haven't got the stamina at the moment to go through all the rest of your links, but I hope you'll find that the fact that the two first have been debunked, may point to how problematic a lot of the research is. For more on why this is so, see http://cyclehelmets.org/1052.html#17. Another point worth learning about is "confirmation bias". Edit: Couldn't help myself: I took a look at the other links, too, and it seems that most of them refer to the first two. |
The BBC article basically says:
-Here is some research that brings into question the effectiveness of helmets, how interesting. -This research may not be robust enough for a strong refutation of popular ideas. -BUT, I have heard a few anecdotal stories that speculate that helmets are effective so I'll go with that. Either way the effectiveness of helmets is heavily contested. I agree with Hagen and think there is a significant degree of confirmation bias involved. Either way, its not as straight forward as most people assume. It's split. It's a maybe. Keeping this in mind, consider the following example: An infomercial claims that a certain supplement will protect you from Alzheimers. The research is inconclusive. It's unclear if it really makes a difference. It's about $20 a bottle and requires multiple daily doses, before every meal. On the bright side, if it doesn't work it's probably harmless. Do you buy it? |
instead of quantity of studies you should have focused on quality of studies. every link either established that helmets MIGHT help or simply from the outset tried to establish what head injuries were involved in bicycle accidents, not overall injuries. and one link seemed to address smoke alarms for whatever reason.
until all injuries and manner of deaths are accounted for in a comparative analyses, focusing on head injury accidents alone will only tell you that hitting your head is bad. guess what a study of using a bike helmet vs. a motorcycle helmet would conclude? if you're mountain biking, wear a helmet. if you're riding black ice, wear a helmet. if you're riding in a herd, wear a helmet. want to stay out of the hospital? learn how to ride a bike. oh and drummerboy thanks for the link http://www.easyfreesmileys.com/smile...ileys-1051.gif |

Do you smoke (like he did)? If you think this is a good argument for not wearing a helmet, you've lost the argument. |

On a side note, I can't help but notice how often the helmeteers produce posts full of spelling and grammatical errors - while at the same time claiming that their interlocutors are the ones with no brains worth protecting. |

The first one was debunked by Robertson, the second by Elvik. Elvik further noticed that the newer the research, the smaller the advantages seemed to be from helmet-wearing. But You really should know that by now, as I've already linked to his paper.

Edit: Couldn't help myself: I took a look at the other links, too, and it seems that most of them refer to the first two. Look, pro riders are always looking for ways to shave weight, if they felt that helmets were useless they would be throwing them in out in groves...their not doing that. If Robertson and Elvik somehow are proven to be 100 percent correct, which I seriously doubt, then you will see pro's throwing their helmets away. Like I said before, if I feel wearing a helmet will give me just a 1% greater chance of surviving a crash then it's worth it. Personally I think the studies that show the effectiveness of helmets to be 50% to 65% effective is correct based on years of studies, and that's 49% to 64% more then I need to want to wear one. I don't buy the most expensive helmet on the market either because I don't believe the most expensive helmet will do anything better then a middle of the line helmet or even a low end helmet like those at Walmart, but I pay a bit more to get the cooling vents and to get a proper fit. Proper fit to me is key to personal head protection, if the helmet doesn't fit right or isn't adjusted correctly it could fail to do it's job in an accident, and that's been proven. So any ineffectiveness of helmets is partially due to improper fitting and adjusted helmets. |
Rekmeyata, the third "study" you cite isn't a study, it's a policy paper. And it relies for its assertion that bicycle helmets are effective on the long-discredited Thomson study.
Three down, seven to go. |

after they became mandatory didn't the TdF eliminate helmets for one stage because it was too hot? yep, them pro's don't like the helmets. they like the sponsorship of a helmet maker. but sadly it's been a year now since Wouter Weylandt died racing the Giro, wearing a helmet.

The point is, you are treating the argument that helmets are effective as some incontrovertible truth, which is empirically false. There are few studies that support the claim, and some of them have been questioned by other experts for their methods, or "debunked". Even then, there are some studies actually showing some negative effects. So, I don't think it's the issue of thinking a helmet might help that is silly, but rather treating it like it is some monolithic truth with tons of evidence supporting it, and that everyone who doesn't agree with it must be stupid. Seatbelts, etc, have plenty of evidence showing their effectiveness and this is not really questioned or debunked by experts... there is much more debate surrounding helmets, and that alone should say something. To cut off an old argument at the pass, if you say "Well what could it hurt to wear one if it may help?", that argument can clearly be used for anything, including body armor. So why doesn't everyone wear body armor, when there are obviously some situations it would be helpful? Convenience. We sacrifice safety for convenience every day (which is especially funny, as you'll see in a moment). For you, wearing a helmet may not be inconvenient. It is for me. Not only do I sweat more in Fresno heat, but it's a PITA for me. They always get stolen if you leave it with the bike (yes, they cut the straps if you lock it; no, I don't know why), and they're a pain to tote when I already have a bag full of books to lug around campus. So, can you see why someone other than you might, after looking at conflicting studies even showing their effectiveness, and studies that actually show them as unsafe in some ways, decide that the extra convenience might outweigh the presumably small benefit (presumably because there is no resounding evidence to support it like there is seatbelts, etc)? Understanding this can go a long way to having civil discourse on the matter. Look, pro riders are always looking for ways to shave weight, if they felt that helmets were useless they would be throwing them in out in groves...their not doing that. If Robertson and Elvik somehow are proven to be 100 percent correct, which I seriously doubt, then you will see pro's throwing their helmets away.

Actually, you are completely wrong about that. Pros wear helmets because the UCI made them mandatory, and their introduction was fiercely resisted. In fact, when the UCI first tried to introduce the ruling there was a revolt, riders refused to comply. Later, the UCI took advantage of the shock of a pro dying of a head injury to bring in the rule, despite further protests. And as it happens, pros have died more frequently since the helmets have been compulsory, though the numbers are so small that proves nothing either way.
And if you visit one of the towns in Europe where a lot of pros go to train, you will see that very many of them, when out training, aren't wearing helmets. Helmets were never a pro preference, they've just had to get used to them because they are now required in competition. |

There has been a drop off in head injuries since helmets have become more popular, this is a recorded trend, the trend does not show an increase in head injuries since helmets became popular. We are talking percentage wise here, there has been an increase in head injuries due to more and more people riding bicycles, but percentage wise head injuries have declined a lot. Again, not saying helmets will protect your head all the time, but the statistics prove it will protect your head 50 to 65% of the time depending on the statistic, meaning you have at least a 50% better chance of coming out alive if wearing a helmet then not. And these statistics are based on 40 years of study. So I'm sorry if I come across like a helmet Nazi, but until the medical world gets on board with those studies that show helmets to be 100% useless I will continue to wear a helmet and I will continue to suggest people should wear helmets as well. Maybe I'll tone down the act a bit though!! |
Hey, by looking at your posts in another thread, I find that you seem to have a quite good grasp of how you must personally act to avoid dangers (better than some others who seem to rely a bit too much on preconceptions). However. I must say that you don't come across as one who is particularly good at more abstract reasoning. Again in the post above, you refer to studies that have been proven to be false and doctors who mostly know nothing about what helmets can or can't - and both these things have recently been shown in this thread. It really appears that you don't read what I and others have to say. Or perhaps you do, but then you don't understand the content. Like with the links you found to "prove" the efficacy of helmets.
