Yes, I said that. I would *never* force you to wear a helmet, however I think it is negligent on your part not to. OTOH, it's a free country. So if a car hits you when you're out walking and your head is injured, can we say you were negligent to not wear helmet? It's a simple and pertinent question.

Excuse me, sir. Please explain to me exactly how the fact that you spew a string of silly-assed questions onto Usenet places me under some kind of an obligation to provide you with answers. You address that question, then we'll consider yours. Nice dodge attempt. You're under no "obligation" to answer my question, but if you can't answer my questions it surely undercuts your earlier assertion. My questions are for analogous situations to the one in which you claim a person not wearing a helmet on a bike is somehow partially liable to damages he/she gets simply due to the fact that he/she is not wearing a helmet. If your claim is true, it should hold up in similar situations involving other types of activities and injuries. So here are the questions for you again: What about if I'm driving a car and hit you when you're walking on the sidewalk? That happens all the time -- is some of the liability for the injury yours? What if I'm driving and you're sitting in the back seat of a car and injure your head? Should you have been wearing a helmet? What if you're in a car that doesn't have side curtain airbags and I hit your car with mine, from the side? Is some of the liability yours? You assume risk when you go out for a walk on the sidewalk, or when you go for a ride in somebody else's car, or drive in a car with less than optimum safety features, or... (etc.) |

That pretty much sums up your argument -- it can't stand up to a simple and closely related analogy. Well, OK, I will answer your questions on a quid pro quo basis. First, you must answer a question of mine in essay format, then I will answer one question of yours. You must first respond to me, only then will I respond to you. That is *my* standard response when someone tries to run the old "give me answers" troll on me. I have seen that one used all over Usenet. It's quite common in the "alt" hierarchy; however, one encounters it as far south as the support groups, occasionally. See also: the "more information troll" and the tried and true "give me a citation troll". If that's OK with you, then I will post my first question. I doubt that you will because you're not seeking any answers; you simply want to grab control of the conversation. Jones |

Ideally we'l change our behavior based on the better information. Or at least, if we can't we'll recognize our irrationallity and not argue about it, stating facts that are untrue such as IJones recently has to support it. We'll just shut up. And if we don't, like IJones, we deserve to be mocked and disrespected. |

To begin with, people who have delved into this in an impartial manner have noted that almost all "bike helmets are very effective" papers are case-control studies with self selected subjects. You've claimed ignorance of the "case-control" term, so I'll explain. Hospital ER records are examined for presence of head injury, and for claimed use of a bike helmet. Percentage head injured are computed for those with and without helmets, and comparisons are made. In some studies, comparisons are also made with cyclists contacted randomly in their homes. Again, these always show some benefit to helmets. The record is the "85%" of the Thompson and Rivara study (which you blithely added to your list, despite your prior assertions that it was worthless!). That alone should give you a clue that your list is, at the very best, overly credulous. The major problem with such studies is that they are ALL based on self- selected subjects. People choose whether to wear a bike helmet, and subjects choose whether or not to go to the ER after a fall off their bike. In 1989, the same terrified-of-brain-injury folks that donned the earliest bike helmets also ran to the ER as soon as they tumbled off their bikes. (Correction: The terrified parents drove them to the ER.) This showed up in various ways - e.g. that the ER saw roughly seven times the helmet use as did street surveys, and that the bike helmets "prevented" about 3/4 of the leg injuries. And, as was immediately pointed out, those early helmet adopters were much more likely to be kids riding with parents (vs. riding alone), on bike trails (vs. streets), falling on soft surfaces (vs. hard), involved with motor vehicles (vs. simple tumbles) etc. We have an exact analogy in the issue of Hormone Replacement Therapy for post-menopausal women. The early, volunteer adopters of HRT showed much less heart disease. Based on that, HRT was widely prescribed for a while - but larger studies involving non-self- selected women showed HRT greatly _increased_ the risk of heart disease (and as is now known, breast cancer). They rarely prescribe HRT these days; in fact, they caution against it. Self selected subjects tend to be much different from the general population. Their different behavior twists the results. You simply can't accept such evidence - which is why the FDA uses double blind tests of drugs. It would never accept studies like these for any medical use. Other supposedly pro-helmet studies are really just jumping on the publication bandwagon, using any justification at all to get something in print, because pro-helmet garbage has to meet almost no standards at all. For example, someone recently pointed to the Berg & Westerling paper out of Sweden, claiming it "proved" helmets reduced head injury. Even ten minutes of reading showed it to be garbage. The conclusions were based on the following "facts": Helmet use in Sweden was assumed (not measured) to have increased in the past ten years. The number of head injuries of adult cyclists hadn't changed. The number of head injuries of kids dropped about 11%. There was no data on the amount of kids cycling or how that had changed. But since there was a modest decrease for kids, and since it's assumed that kids helmet use rose, then the helmets MUST have been effective in causing that decrease! (Um... but we won't mention the adults again.) Can you name another field in which such a paper would be accepted?? Furthermore, many pro-helmet papers (including, I believe, some you've cited) do not examine the effect of helmet use. Instead, they take as a given that helmet use MUST reduce head injuries, and they examine methods of forcing people to wear helmets. Their abstracts often contain phrases like "Bicycle helmets have been proven effective in reducing head injuries" (most often, followed by a citation of the "85%" garbage study) but the point of the paper is compulsion, not examination. What you need to find is this: Time series data that involves a large percentage of a jurisdiction's population during a time when helmet use increases, preferably increases rapidly (so environmental variables don't confound things). You need to correlate _serious_ head injuries _per cyclist_ with helmet use. And BTW, you need a true control group, since medical technology, diagnostic techniques and hospital admission standards change over time, and fewer people are admitted as years go by. Pedestrians form a useful control group; that is, if serious pedestrian head injuries decline in the same manner that bicyclist head injuries decline, then any increase in bike helmet wearing means nothing. Unless, that is, you really did get the peds to start protecting their heads. Oh, one more thing: Be sure the study properly defines "head injury." Thompson & Rivara, in coming up with their "85%" figure, counted cut ears and scratched chins as "head injuries." Many other pro-helmet studies have used similar word tricks. For what it's worth, I've looked for studies like that - i.e. non self- selected and all the rest - but I've never found one that showed any significant helmet benefit. That's the main thing that changed me from a helmet promoter to a helmet skeptic. Let me know what you find. - Frank Krygowski |
