What is a fallacy? Give examples of fallacies and describe how the argument can be deceptive.
Society has an obligation to provide health insurance because healthcare is a right of citizenship. This argument is deceptive because the premise and conclusion essentially say the same thing.
The patient is still breathing, so he must still be alive. This argument is deceptive because it makes a generalization about people who are breathing, but the premise has nothing to do with being alive.
Company X makes the best pickup trucks in the world. More people drive Company X pickups than any other light truck. This argument is deceptive because the fact that a large number of people buy Company X pickup trucks does not necessarily mean that they are the best trucks.
I placed a quartz crystal on my forehead, and in five minutes my headache was gone. The crystal made my headache go away. This argument is deceptive because it claims that because one thing happened before another, the first event caused the second event, but it doesn't prove that there is any connection between the two events.
