Strong and Weak Induction
Captions available
The idea
An inductive argument is strong when true premises would make its conclusion probable, and weak when they would not. Strength comes in degrees.
In practice
"Ninety-six percent of a thousand sampled batteries passed, so this one will" is strong. "My cousin's battery died" is weak.
Where people slip
Even a strong argument's conclusion can turn out false. Probability is not a promise.
