- The first video on “Why We Shouldn’t Bike with a Helmet.” , by Mikael Colville-Andersen, Colville-Andersen is a designer and urban planning consultant. Andersen first use of evidence was comparing the most livable cities in the US to bicycles. He showed us the best cities and then highlighted top 12 which all had a high level of bicycle traffic in their cities. With that said he transitions his next piece of evidence, or expert testimony from a Norwegian philosopher. His next pieces of evidence were more of examples that in reality we are all risks and at any given time some freak incident could happens and living in fear is lucrative and only helps business. In short, he had many types of evidence and made use of significant stats and expert testimonies to help his claim.
- The second video on “The Importance of Bike Helmets.” by Fred Rivara, a physician and Professor in Seattle, took a different approach on his claim. Being a physician and professor he his. He looked a the medical side of things. Black and white, using many statistics, and studies regarding brain damage, the downsides of bicycling (injuries,hospitalizations, deaths). After showing the dangers of death he then shwoed more statisitics of the positives of riding bikes which proved that helmets worked. Showed high percentages of injuries prevented by helmets of the face, brain, or head.
Both videos showed different uses of evidence and were both effective and tailored to their respective claims.
