Heuristic
adjective / noun /hjʊˈrɪstɪk/ — A mental shortcut that's usually right.
Definition
A practical mental strategy or rule-of-thumb that helps solve problems quickly; not guaranteed to be perfect, but good enough for most situations.
Beyond the definition
Heuristics are how humans manage a complex world without infinite time. We can't reason from first principles for every decision — so we use mental shortcuts. The best heuristics are the ones you've tested enough to trust.
Origin & history
From Greek heuriskein — to find, to discover. Related to 'eureka!' (I have found it).

Heuristic vs algorithm
An algorithm is a precise, step-by-step procedure guaranteed to produce a correct result — it is exact, exhaustive, and systematic. A heuristic is a practical shortcut: faster and simpler than an algorithm, good enough for most situations, but not guaranteed. Algorithms eliminate uncertainty; heuristics manage it. In a world where we can't compute everything from first principles, heuristics are what make us functional — at the cost of occasional error.
Word in the Wild
Illustrative story: an imagined scene, not a documented event or interview.
He had spent twenty years hiring people and had refined the process down to three questions he asked in every interview. Not the questions companies put in books. His questions.
He couldn't fully justify them theoretically. But they had a predictive track record he trusted more than any formal assessment. The best people always gave a specific kind of answer to the third one.
A colleague asked him once to explain the third question. "I can tell you the question," he said. "I can't tell you exactly what I'm listening for. I know it when I hear it." That's the whole thing.
