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)
