PSY 101 · Lesson 13 of 20

Thinking and language

Why does a good decision still feel wrong when a rare disaster is easy to picture?

The availability heuristic is using ease of retrieval as a cue to probability (Tversky & Kahneman, as treated in Myers & DeWall, 2021; Spielman et al., 2020). Cognition includes that judgment. An algorithm would grind through a procedure that guarantees the answer if one exists. The heuristic is faster and sometimes wrong. A name that comes back to mind easily can be judged as more common than it is.

If a language has no single word for a distinction, does that mean speakers cannot think the distinction?

Not by itself. Language is a productive symbol system. Linguistic relativity is the hypothesis that language shapes habitual thought. Evidence is mixed and specific; intro texts should keep it as a hypothesis. Figure 13.1 contrasts algorithm and heuristic so a later paper that says “participants decided” can be asked which kind of procedure they used.

ProcedureWhat it doesCost
algorithmFollows steps that guarantee a solution if one existsSlow; needs a well-defined problem
heuristicUses a shortcut (including ease of retrieval)Fast; can be biased
Figure 13.1 Two ways to reach a judgment. Figure 13.1 is a comparison of procedures, not a ranking of intelligence.
