1.1 Identifying logical fallacies transcript
Introduction
Jake has to write an essay on the following topic: “There are many health benefits to eating a vegetarian diet. Discuss.”
Jake says:
Person 1
Akamu, Jake’s best friend, says:
Question
- anecdotal evidence
- burden of proof
- ad hominum
Answer
2. burden of proof.
Akamu refuses to believe in the benefits of vegetarianism unless someone else proves that it is definitely effective. Therefore, he is putting the burden of proof on people who do believe in eating a vegetarian diet.
Person 2
Daniyah, Jake’s classmate, says:
“Listen, I saw a documentary by a famous scientist – I can’t remember his name, but he’s really well regarded. He said that avoiding meat leads to some amazing health benefits. I mean, if he says it’s true, then it’s true because he’s a scientist and he made a documentary about it.”
Question
Daniyah’s argument is an example of:
- appeal to authority
- burden of proof
- correlation-causation
Answer
- appeal to authority
Daniyah’s opinion is based on the views of an expert. However, Daniyah is not sure who the expert was, and she has not done any of her own independent research into the qualifications of the scientist or the topic.
Person 3
Hans, Jake’s dad, says:
“Well, I was going to become a vegetarian until your mum’s friend, Neha, told me about what happened to her. She said that after a year with no meat she was so tired and weak that some days she couldn’t even get out of bed.”
Question
Hans’ view is an example of:
- burden of proof
- anecdotal evidence
- conspiracy
Answer
2. anecdotal evidence.
This is an example of anecdotal evidence because Hans has based his opinion on information he has heard from another source. In this case, he has not seen this ‘proof’ with his own eyes and does not know if what Neha said is true or accurate.
Person 4
Eli, Jake’s boss, says:
“Vegetarianism? Surely you know that’s all a load of rubbish. I thought you were smarter than that! Is that what they’re teaching you at university? You should stop wasting your time studying if you’re not learning anything worthwhile.”
Question
Eli’s view is an example of:
- ad hominum
- anecdotal evidence
- conspiracy
Answer
1. ad hominum
Instead of developing an effective counterargument against vegetarianism, Eli has attacked Jake’s intelligence.
Person 5
Huerta, Jake’s yoga teacher, says:
“Well, I’m healthy and I’m a vegetarian, so having a plant-based diet is obviously good for you.”
Question
Huerta’s argument is an example of:
- conspiracy
- anecdotal evidence
- correlation-causation
Answer
3. correlation-causation.
Huerta has made an assumed connection between two things without having any real evidence that they are linked.
