The Burden of Proof: Why People Must Support Their Arguments

Specifically, each person in a debate has a burden of proof with regards to their own claims, so that if they want their claims to be accepted by others, they must provide proof which supports those claims, either as part of their original argument, or in response to their opponent’s questions.

In general, a person has a burden of proof with regards to any arguments that they make, which means that they have to provide sufficient evidence in order to support those arguments. This means, for example, that if a person supports the prevailing status quo in some field, which has already been proven to be true in the past by others, then that person needs to reply to challenges against their view only in cases where the challenger has first fulfilled their own burden of proof to a reasonable degree.
