a generalization.
2. Causal reasoning is cause–effect relationship reasoning.
a. Demonstrate that certain events or factors (causes) produced, or in some
cases prevented, a certain result (the effect).
b. Inoculation: Mentioning other causes is “vaccinating” your audience
before they have time to consider other possible causes.
3. Deductive reasoning is when the speaker takes general premises and draws a
conclusion from that general information.
a. Often set up as a syllogism with a major premise, a minor premise, and
then a conclusion.
b. You must make sure the major and the minor premises are accurate.
