Letter to the editor: I have never seen such flawed reasoning and distorted evidence as that which you tried to pass off as a balanced study in the article "Speed Limits, Fatalities, and Public Policy." The article states that areas with lower speed limits had lower vehicle-related fatality rates than other areas. ████████ ████ ████ ███ ██ ████ ███ █████ █████ ███████████████ ████████ █████ ███ ██████ ██ ███ █████ ████ █████ █████ ███████ ██ ███ ████████ ████████ ████████ ███ ████ ████ █████ ██████ ██████ ██ ██████████
The letter concludes that the evidence supports increasing speed limits, even though areas with lower speed limits also have lower vehicle fatality rates. This is based on the observation that fatality rates are rising in areas with lower speed limits.
The letter’s argument is flawed because it draws a conclusion about the safety of areas with low speed limits relative to other areas, while only considering evidence about areas with low speed limits. In other words, the argument fails to consider whether the same increase in fatality rates is happening in areas with higher speed limits.
