heuristic
hyoo-RIS-tik
/hjʊəˈrɪs.tɪk/
A practical problem-solving shortcut or rule-of-thumb that is sufficient for immediate goals, though not guaranteed to be optimal or perfect.
Trades absolute precision and exhaustive logic for speed and practical utility when tackling complex problems.
The story behind the word. From Greek 'heuriskein' (to find or discover)—the exact same root as Archimedes' famous exclamation 'Eureka!' ('I have found it!'). German philosopher Albert Einstein brought 'heuristic' into modern physics in his 1905 paper on light quanta, describing his idea as a 'heuristic viewpoint'—a useful model that helped discover truth even if incomplete.

When not to use
Do not use to describe a rigorous mathematical algorithm that guarantees an exact answer.
Fun facts
- Nobel laureate Daniel Kahneman spent decades documenting how human mental heuristics—while efficient for ancient survival—cause systematic errors in modern financial investing.
