Burdon of Proof
The burden of proof is the obligation on a party in an epistemic dispute to provide sufficient warrant for their position in any discussion.
When debating any issue, there is an implicit burden of proof on the person asserting a claim. This burden does not necessarily require a mathematical or strictly logical proof, although many strong arguments do rise to this level.
Rather, the evidential standard required for a given claim is determined by convention or community standards, with regard to the context of the claim in question.
Assuming both sides have agreed to reasoned discourse, the burden of proof can serve as an effective tool to ensure that all relevant arguments from both sides of an issue are introduced.
After assertions are established the mechanism of burden of proof takes over to keep those engaged in discourse focused on providing evidential warrant and cogent arguments for their positions.
