Heuristic
A practical shortcut can guide a judgment or search without guaranteeing the best answer.
Definition
A heuristic is a simplified strategy or rule that reduces the information or effort needed to make a judgment or solve a problem.
How to understand it
Heuristics are useful because decisions often arrive with incomplete information and limited time. Rather than examine every possible option, a person may rely on a cue or a manageable sequence. The important question is whether the shortcut uses information that is reliable in the setting where it is applied.
A shortcut is not automatically a bias. A heuristic can produce a reasonable answer while sometimes producing predictable errors. Evaluating it requires a comparison standard and an account of the task. Calling an unwelcome decision heuristic reasoning does not establish either the mental process involved or the decision’s quality.

Choosing a place to start
Teaching scenario
A fictional student searching a crowded library begins with books published by recognized academic presses, then checks each candidate’s subject and evidence. The initial publisher rule narrows the search without proving that every remaining book is suitable or that excluded books lack value. It may be useful when time is limited. If the task changes to locating community testimony, the same shortcut may miss central material. The example shows why a strategy’s usefulness depends on the question being asked.
Constructed for learning. This scenario is not a report of an empirical finding or a diagnosis.
Common confusion: Algorithm
An algorithm specifies a procedure; a heuristic simplifies a search or judgment and generally provides no guarantee of a correct answer.
Evidence: (Spielman et al., 2020); (Judgment and Decision Making, n.d.)
Limits of the concept
- A plausible description of a shortcut is not proof that a particular person used it.
- A heuristic’s accuracy depends on the environment and the information its rule retains.
