An inductive argument is one that starts with one specific case and tries to generalize from there. This is in contrast to a deductive argument in which a person starts with a general rule and tries to apply it to a specific case.
Let us look at an example of inductive reasoning. Let's say that I meet a person who is from Japan and that person does not like baseball. From that, I infer that all Japanese do not like baseball. I am taking one specific case and trying to create a general rule based on that case.
