Strength Revisited

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

Inductive strength comes in degrees and moves with evidence — new information can strengthen or weaken an argument without touching its form.

Show

Add one premise ("the sample was all volunteers") and a strong argument sags.

Watch for

Validity is immune to new premises; strength never is. That's the deepest difference between the two halves of logic.
