Statistical errors in anti-helmet arguments

Bicycle helmets are designed to mitigate head injury during a collision. In the early 1990’s, Australia and New Zealand mandated helmet wearing for cyclists in an effort to increase helmet usage. Since that time, helmets and helmet laws have been portrayed as a failure in the peer-reviewed literature, by the media and various advocacy groups. Many of these criticisms claim helmets are ineffective, helmet laws deter cycling, helmet wearing increases the risk of an accident, no evidence helmet laws reduce head injuries at a population level, and helmet laws result in a net health reduction. This paper will demonstrate the data and methods used to

support these arguments are statistically flawed.
