John and Lisa met on vacation and were discussing their favorite places.
John: Jamaica is the best place in the world and has the best people.
Lisa: Really! I'm flattered. Why do you think Jamaica is so amazing?
I'm seeing mermaids, unicorns, aliens and skeletons on the beach which means I am drunk, therefore Jamaica is the best place in the world.
I went to Jamaica and was first greeted by a group of Rastafarians. Therefore: all Jamaicans are Rastafarians and I love Rastafarians.
My apologies. I have other really good reasons why I think Jamaica is the best.
Well John, not all Jamaicans are Rastafarians. You made a bit of a hasty generalization when you assumed based off the first few people you saw, that all Jamaicans are Rastafarians. You drew a general conclusion from a tiny sample.
Circular Reasoning: An argument is circular if it conclusion is among its premises, if it assumes what it is trying to prove.
Jamaican People are always happy because they all constantly smoke weed.
So they can all be happy all the time.
Why would Jamaicans constantly smoke weed?
Not all Jamaicans smoke weed. John
False Authority: The reasoner uses the assumption that an expert in one field is also an expert in another.
He is a professional, he knows what he is saying. It must be like science or something.
My Urologist says Jamaica is certainly the best place in the world, so it must be true.
So what does your Urologist know about places in the wold?
John, your argument is Non Sequitur. This means that what you are saying does not logically follow from a premise or conclusion.
It was nice meeting you. You seem like a nice person. It must be because you are from Jamaica. All Jamaicans are good people.
Thank you John but your argument is genetic. This means you assume something is good or bad based on its origins.
