You would have to explain why this is not relevant when discussing helmet effectiveness in reducing bicycle deaths. So, are you now claiming that a certified-for-mere-14mph helmet is actually very effective in preventing cycling fatalities? That's contrary to what we've heard from your team before, when you folks were saying "It's not about the fatalities." Admittedly, I have trouble keeping track, but which "team" said: "The Dutch and Danes fall from their bicycles, unhelmeted. There should be monstrous levels of death and debilitating head injuries." Yeah, right. I'm with you, though, that common bicycle helmets suck. Are you simultaneously claiming that the only significant difference between a helmet wearing cyclist and one who chooses not to wear a helmet is that hat? In other words, do you disagree with Crocker that other coincident factors were the actual causative mechanisms? More specifically, whom do you observe more frequently riding facing traffic - helmet wearers or those without helmets? Who do you suppose are more often biking drunk? Who more often rides at night without lights? Who more often ignores stop signs? And do you think that slapping a helmet on a wrong-way, no-lights, stop-sign-running drunk cyclist will change him into a careful law- abider? No, not at all (no way, no how, in fact) - but he may have already been a much safer bicyclist than the holier-than-thou-stop-sign-school- marm. If so, you have no comprehension of the term "confounding factor." Which is not surprising, since you've absolutely refused to read anything of substance on this issue you're discussing. |

Yeah, right. I'm with you, though, that common bicycle helmets suck. The fatality statistic alone makes a darn good argument by inference that helmets are indeed effective in reducing greatly the likelihood of death by bicycling. A successful argument to the contrary would have to invalidate statistics as a science; invalidate the report that found very high negative correlation between helmet wear and fatalities; or explain the as yet unvoiced confounding factors that invalidate this conclusion. In any case, the test standard for bicycle helmets is relevant only to the extent that the word "helmet" is understood to mean a bicycle helmet certified by its manufacturer as meeting or exceeding the applicable standards.

No, not at all (no way, no how, in fact) - but he may have already been a much safer bicyclist than the holier-than-thou-stop-sign-school- marm. I will state for the record unreservedly that my opinions and observations did not in any way influence the reported finding that 97% of the study fatalities were not wearing helmets. That needed saying only because Frank needs help keeping his thoughts on track. In other words, it goes without saying. If so, you have no comprehension of the term "confounding factor." Which is not surprising, since you've absolutely refused to read anything of substance on this issue you're discussing. See above. Frank Krygowski's inability to think critically and stay on topic is the single most confounding factor in this discussion. So far, the conclusion stands as stated: Helmet wearers are very significantly under-represented in the bicycling fatalities reported by the NY study. Ergo, wearing a helmet while bicycling is effective at reducing the likelihood of death by bicycling. |

A successful argument to the contrary would have to invalidate statistics as a science; That's not even remotely true. Statistics as a science includes evaluating the effects of confounding variables in studies. The report you are touting makes no effort to even list confounding variables, let alone account for them using statistical methods. Briefly, your knowledge of statistics is obviously lacking. Although they won't educate you on the techniques, some of the papers I've cited will at least give you an idea of what competent statisticians do to account for extraneous variables. So far, the conclusion stands as stated: Helmet wearers are very significantly under-represented in the bicycling fatalities reported by the NY study. Ergo, wearing a helmet while bicycling is effective at reducing the likelihood of death by bicycling. Let's remember: Crocker of Austin Texas thought that his study would show similar benefits for adult cyclists. He actually ran the study expecting it would give him ammunition with which to push for an all- ages mandatory helmet law. But he found instead no detectable benefit for helmets. And why? Because he included data on alcohol use. Including that confounding variable showed that it was the alcohol in the blood stream, not the lack of a helmet, that correlated with head injury. The helmets were not protecting to any statistically significant degree. This illustrates the problem with simplistic correlations like the one you - and that propaganda's authors - are making. - Frank Krygowski |

The helmets were not protecting to any statistically significant degree. This illustrates the problem with simplistic correlations like the one you - and that propaganda's authors - are making. Has there been an update since 2008? http://www.goodhealth.com/articles/2...ohol_use_risky "We found that bicycle riders who had been drinking or using drugs - far away more alcohol than drugs - were four times more likely to have a head injury. While riding the bike after consuming alcohol, only one out of 40 patients was wearing a helmet, so it appears that one of the first things that happens is that riders don't bother with helmets." The study has been extended for another year to confirm another finding: That cyclists without helmets are twice as likely to have a significant head injury. "We looked at experience of the rider, street conditions, weather conditions, type of street, location in city and use of drugs or alcohol. In all truthfulness, I suspect data will show that wearing a helmet improves safety, but we won't know for sure until the study reaches statistical significance," adds Dr. Crocker. This article (are there newer ones?) doesn't seem to fully support your claims. |
