Deductive Reasoning
Captions available
The idea
Deductive reasoning draws conclusions that must be true whenever the premises are true — no case can make the premises hold and the conclusion fail.
In practice
Every machine in an early computing room runs on vacuum tubes; the corner machine therefore does too.
Where people slip
A guaranteed conclusion still inherits any error in a premise.
