The Burden of Proof

In one line Whoever makes a claim owes the reasons for it.

A claim arrives with the work still attached. The person who asserts a hidden fact (a bakery is a front for crime, a number is a plot) owes the reasons. “Prove it is not true” moves that work onto everyone else, which is a way of skipping it.

Hume’s rule is proportion: a wise person’s belief matches the evidence. A claim that names a result that would make it fail has taken on a burden you can actually check. A claim that counts every result as support has not risked anything.

Skepticism here is not a pose of universal doubt. It declines to treat an accusation, or a story that no result could count against, as if it had already done its share.

Prove the bakery innocent

Illustration: Prove the bakery innocent

A post says the bakery on your street is a front and tells skeptics to disprove it. You have no dossier. The absence of your rebuttal is then offered as evidence.

That is the burden sliding off the claim and onto the reader. The next honest sentence asks what the post itself has, besides the instruction to disagree.

Try this today When someone says “prove it isn’t true,” ask them for their own evidence first.

Question 1 of 2

A post accuses a local bakery of being a front and tells readers to prove that it is not.

Where does the burden sit?

Question 2 of 2

A coworker says the new hire got the job through a family connection, and adds, “Nobody can show that she didn’t.”

What is wrong with the coworker’s reasoning?
