For my first presentation I looked at the TED Talk “Why we Shouldn’t Bike with a Helmet” by Mikael Colville-Andersen. I went through his speech and looked at things that contribute to credibility such as virtue, intelligence and goodwill and how he used them to try and convince the audience of his argument. I found this to be a really interesting video to use for this presentation as all his evidence only supported not using helmets but he still made sure that he told the audience there was another side to the debate and did not forcefully put his opinion on them.
