Core distinction and conditions
Several thinking concepts can produce a poor decision, but they describe different processes. Functional fixedness restricts an object to a customary use. A mental set persists with a familiar solution strategy even when another approach would be useful. Availability uses ease of bringing examples to mind as a judgment cue. Confirmation bias favors information that fits an existing belief while discounting relevant contrary evidence. Begin with what the person actually does, not with the fact that the final answer is wrong. Similar outcomes can arise from different processes, and a passage may not establish every process that could theoretically coexist.
Worked example: change the decisive observation
An artist cannot find a way to stabilize a small model because a container is considered only as storage. A customary-use restriction supports a fixedness account. Replace that observation with an artist who freely imagines many object uses but repeats a previously successful assembly sequence after the problem’s requirements change. Now strategy persistence supports a mental-set account more directly. The distinction is about the source of the restriction, not whether the object or person has a particular name. To explain the contrast, identify the evidence that supports one account and the changed evidence that favors the competitor.
Evaluate recall cues and evidence selection
If a learner estimates frequency because a vivid example comes to mind easily, the cue is availability. An accessible example is not automatically a representative sample. If a learner searches only for reports supporting a preferred explanation and excludes well-designed contradictory findings merely because they disagree, confirmation bias is the more direct concern. A reasonable evaluation considers both supporting and contrary evidence while checking their quality. This does not mean every contrary result is decisive or that intuition is always useless. It means the way evidence is selected must not make the starting belief immune to an informative test.
Transfer check: identify what would change your label
A solver can imagine unusual uses for an object but insists on a once-successful sequence despite new constraints. Explain why that observation differs from functional fixedness. Then a learner estimates event frequency from a dramatic remembered example even though a reliable frequency table is available. Name the judgment cue and what the table contributes. Finally, suggest how to evaluate a favored study strategy without selecting evidence only in its favor. A completed answer names the process, cites a discriminating detail, and states one condition that would make another explanation fit better instead of merely attaching a familiar label to any mistake.
Try it, then explain it.
Complete a short set without looking at the example. After each answer, explain which evidence or rule supports your decision and why the alternatives do not fit.
