Should you wear a bicycle foam hat while riding a recumbent?

°_° " wrote: While I wrote the above words, I did *not* write them as one paragraph. Combining them is therefore false quotation. Please do not do this again. If foam bicycle hats were effective, why does making previous non-users wear them (e.g. Australia and New Zealand) fail to reduce the death rate due to head injuries? That is all the proof a *rational* person needs to know foam bicycle hats are ineffective beyond bump and scrape protection. Those were Zionist lies from the very beginning, promoted by 5th columnists in the US government (e.g. Wolfowitz, Feith, Perle, Abrams, Libby), in the lobbying sector (e.g. AIPAC), and in the media (all the mainstream outlets) in order to have the US fight a war of destruction on Iraq on behalf of Israel and its goals of regional dominance. My reader is programmed to strip out existing quoted material and leave only the current writing to which I reply. When you write your reply into the body of the previous message, it also deletes empty lines on either side, so it appears as a single paragraph. If you use the essay style, then it will leave your paragraphs intact when empty lines are inside of your text. It deletes my writing, not yours. If your writing depends on mine for its meaning, then you have a problem, I suppose, but I don't. Get over it; it's a computer thing. I will address your question; however, let's agree on the basics: Do you agree that quitting smoking is a healthful lifestyle change that everyone should do? |

You can't start with existing abstracted data, notice a correlation (or lack thereof) in the data, and conclude that one causes (or does not cause) the other. When I took *that* class, protestors were outside chanting about the war in Vietnam! I'll bet that, if I took the time, I can find an example of you quoting a rebuttal of some study you don't like for that very reason. I can take all the data in the world on roosters; however, their crowing does *not* cause sunrise. I got bored with the silly helmet topic long ago... do as you please. |

wrote: Since you don't even know the research I am citing, how would you know the methodology? The method was to use the same rider on the same route at the same time of day, with and without a foam hat. Ultrasonic detection was used to log the passing distance of motor vehicles. On average, motorists gave 8.5cm more passing clearance when overtaking the bareheaded subject. In two cases the subject was struck by passing traffic - both times when wearing the foam hat. A long brunette wig was found to increase passing clearance by an average of 14cm. So how to you interpret the results now you know that this was done properly? No doubt your religious belief in "'s'obvious innit" will produce some additional objection. This is known as moving the goalposts, or policy based evidence making, and is fundamentally dishonest. You've managed to show that you don't bother to read the research you are pointed to, but feel you can comment on it anyway. I agree that I do not know that research. I disagree that you "cited" anything, though. How do I interpret it? Drivers like cyclists wearing helmets? They dislike brunettes? Did they try it with a blonde wig? I know! Helmet manufacturers are embedding magnets in the product. That's it! Boring. |

So in other words you won't take the time, so you won't make the bet, so your stating you will bet is just bluster. If you're not going to do the reading at least have the integrity to admit you're not in a position to lecture those of us that have on what might be contained in the reading.

But isn't it interesting that the number of serious head injuries that occur inside cars, or while traveling on foot, completely eclipses the number that occur while bicycling - yet you never hear of motorists or pedestrians who adopt your tactic? - Frank Krygowski |

In any case, his subsequent paper saying "Wait, I found a benefit!" was thoroughly, mathematically rebutted by Robinson, who pointed out that instead of examining the entire time series data, he simply picked a tiny selection of data points and removed the time coefficient that he'd previously discovered. *THAT is cherry picking, as classic as it gets. Again, all this has been discussed. *Yes, we can cite the specific papers. *Perhaps you should do some reading, to catch up. *You might start he Statistics certainly *can* show that A causes B; however, that kind of study can't. Statistics can (and do) show that ordinary cycling does not impose any unusual risk of serious head injury, despite propaganda to the contrary. And statistics can (and do) show that widespread adoption of bike helmets has not had a beneficial effect on serious head injury rates. Really, that's all that's needed to adequately understand this issue. But if you'd like more, an examination of helmet design and certification standards, plus some knowledge of physics and physiology, give good understanding of why bike helmets are likely to be ineffective. Bicycle helmets aren't exactly a multi-billion dollar industry. *Heck, I can show you identical discussions on handgun safety devices. You persist in trying to change topics. If you really want to discuss smoking or handgun safety devices, you might start a different thread. Actually, this topic is starting to bore me. *I can't think of a more trivial topic on which to spend years and thousands of postings. Well, we could discuss the psychology of those who: 1) fail to study a topic, yet 2) give advice and solicit debate from those who have studied the topic, and then 3) say "I'm getting bored" instead of "I have much to learn." - Frank Krygowski |

wrote: No, but the automotive industry is, and they have every reason to attempt to shift the blame for the vast death toll onto the victims. No, his bosses wanted to promote helmets, so they made him cherry pick some of the data from his original study so that it reversed the conclusion. He was smart enough to do so in such a way that it could be easily dismissed as cherry picking by anyone who bothered to study it, thus managing to avoid trouble with his employers and retain some kind of integrity. Bugger off then. So... bicycle helmets are promoted by Japanese auto makers? Over on the motor racing groups, they say it's an attempt by the ecologists to kill their sport. The dopers blame the juicers. Personally, I like the one about the multi-billion dollar Chinese helmet industry promoting it as an avenue to world domination. But, I do savor conspiracy theories. I figure I can work 9-11, Hitler, *and* the Jews into this one. Do you have any more? |
