Cards (14)

  • Logical fallacies are errors in reasoning that invalidate an argument.
    • False Dilemma – It occurs when the arguer presents his / her arguments as one of the only two options despite the presence of multiple possibilities or options. (Narrowing down the options)
    Eg:
    Child to parent: Either you buy me this new book, or you decide that reading is not important at all.
    • Appeal to Ignorance – It occurs when something is instantly concluded although the argument was not yet proven to be true or false. (Jumping to conclusion)
    Eg:
    No one can actually prove that God exists; therefore, God does not exist.
    • Slippery Slope – It occurs when an exaggerated and superficial series of events were drawn out from a simple argument. (Overreacting to an argument)
    Eg:
    If we ban computer shops, then students will not be able to do research. If they do not have a tool for research, these students will fail their subjects.
    • Appeal to Force – It occurs when a threat is used instead of reasoning.
    Eg:
    If you do not admit that evolution is not real, we will isolate you from the group.
    • Appeal to Pity – It occurs when the element of pity is used instead of reasoning.
    Eg:
    Please do not fire me for being absent all month. I have a sick mother and a special child to support.
    • Bandwagon - It occurs when the argument was accepted or was considered to be valid since the “majority” agrees and believes in it.
    Eg:
    Most Filipino wants to have fair skin because they think they look beautiful. Therefore, having fair skin must be the real standard of beauty.
    • Attacking the Person – It occurs when someone tries to refute an argument by attacking the character of the person instead of attacking the argument itself.
