Co-Proofs
Valosken50

Two opposing attributes of data that cause some change in belief:

Positive Evidence / Lack of evidence

Probability-increasing / Probability-decreasing

Then cross the two to make:

Positive Evidence + Probability-increase = Proof

Lack of Evidence + Probability-increase = Co-proof

Positive Evidence + probability-decrease = Disproof/Counterproof (?)

Lack of Evidence + probability-decrease = Co-disproof? (Probably not)

?

My concept of "proof" (which perhaps I should have tried to define!) is different: evidence which would raise the probability to very near one. Likewise, "refutation": evidence which would lower the probability to very near zero.
