Logic / Unit 1 Logic 029 short lesson, about 20 seconds
Deciding Deductive vs. Inductive
Captions available
The idea
Classify by the claim being made: words like "necessarily," "certainly," "it must be" signal deductive intent; "probably," "likely," "chances are" signal inductive.
In practice
"The sun has risen every day, so it will probably rise tomorrow" — inductive by its own admission.
Where people slip
Absent indicators, judge by the argument's best reading — charity again (024).
