A decision before an answer
- A heuristic is fast because it skips information; the same shortcut that saves time produces predictable errors.
- Your goal: Distinguish concepts, schemas and scripts as representations.
Represent the knowledge
- Concepts group instances; natural concepts have fuzzy boundaries organised around prototypes, so a robin is a "better" bird than a penguin and is verified faster.
- Schemas are organised knowledge structures about domains; scripts are schemas for event sequences. Schemas guide encoding and also distort recall toward the expected.
After heavy news coverage of plane crashes, a person judges air travel deadlier than driving. This best illustrates:

Vivid, easily recalled examples inflate the judged frequency.
Trade speed for certainty
- An algorithm guarantees a solution by exhaustive rule; heuristics trade certainty for speed. Availability estimates frequency by ease of recall, so vivid events are overestimated. Representativeness judges by similarity to a prototype and neglects base rates.
- Anchoring drags estimates toward an initial number. Framing changes choices between logically equivalent descriptions, and confirmation bias seeks only supporting evidence.
A quiet, bookish stranger is judged more likely to be a librarian than a farmer, although farmers vastly outnumber librarians. The error is:

Similarity to the librarian prototype overrides the low base rate of librarians.
Unstick the problem
- Problem solving fails in characteristic ways: functional fixedness (objects only in usual roles), mental set (old solutions to new problems), and missing insight restructuring.
- Means-end analysis reduces the difference to the goal; working backward suits problems with a clear goal state.
Estimating plane crashes as commoner than car deaths after news coverage is the availability heuristic. Judging a quiet bookish stranger more likely a librarian than a farmer, despite far more farmers, is representativeness neglecting base rates. Using a candle only as a candle, not as part of a shelf, is functional fixedness.
A schema for an ordered event sequence, such as visiting a restaurant, is called a ____.

Scripts are event-sequence schemas.
Weigh intelligence claims
- Intelligence theories differ on structure: Spearman's general factor g, Cattell's fluid versus crystallised abilities, Gardner's multiple intelligences, Sternberg's triarchic analysis.
- Test interpretation follows the psychometrics of earlier units: scores are reliable for prediction within their validation samples, but a score measures performance on the test, not a fixed essence.
Calling a heuristic an error in itself; heuristics are efficient defaults whose costs are predictable. Do not equate a test score with a fixed measure of worth or potential.

An algorithm trades speed for a guaranteed solution when one exists.

The trade runs the other way: algorithms guarantee the solution at the cost of time; heuristics are fast but not guaranteed.
Keep the distinctions
- availability heuristic 可得性启发式 — Estimating frequency or likelihood by how easily examples come to mind.
- representativeness heuristic 代表性启发式 — Judging probability by similarity to a prototype, neglecting base rates.
- Distinguish concepts, schemas and scripts as representations.
- Compare algorithms, heuristics and their characteristic biases.
- Evaluate intelligence theories and what test scores support.
