thought experiments
Imagined test cases
Thought experiments are imaginary scenarios used to explore concepts, test hypotheses, or probe intuitions—reasoning conducted entirely in the mind rather than through physical testing.
Philosophy and physics rely heavily on them: Schrödinger's cat illustrates quantum superposition, the trolley problem probes moral intuitions about harm.
It's a thought experiment, not a policy proposal.
The method lets thinkers isolate variables and examine implications that would be impractical or impossible to test in reality.
