Drawing valid conclusions: deduction, induction, analogy and maths.

Reasoning is drawing valid conclusions by applying logic: deduction, induction, analogy and mathematics.

The Wason selection task shows how framing matters: people often fail the abstract version but solve the same logic framed as a social rule.

Sub-facultyItemsStatus
Deductive reasoning
Drawing only the conclusions the rules allow, including which case could prove a rule wrong.
How it differs: The rule is stated, so nothing has to be learned or guessed; the work is in following its logic strictly. In rule induction and in learning from feedback, the rule is hidden and has to be found. Compare all four →

Humans. Experts do well on hard questions in their own field. On the abstract Wason task, most people pick the card that confirms the rule instead of the one that could break it.

AI. Frontier models now outscore PhD experts on graduate-level science questions. Textbook logic puzzles are widely published online, so scores on them say little.

Complete the analogyspecimen · not scored

Pick the word that completes the analogy.

(a) Question

  1. 1. Sculptor is to statue as baker is to …
    (a) oven(b) bread(c) flour(d) kitchen
Figure 1. A four-term verbal analogy. The wrong options are all linked to baking; only one matches the maker-to-product relationship. Benchmark: Webb, Holyoak & Lu (2023). Answer: Bread: a sculptor makes a statue, a baker makes bread.

Check the quick answerspecimen · not scored

Read the problem, then type the number.

(a) Stimulus

A bat and a ball cost $1.10 in total. The bat costs $1.00 more than the ball.

(b) Question

How many cents does the ball cost?

Figure 2. The best-known cognitive reflection problem (Frederick, 2005). Most people first think 10 cents. Our live items are new problems built the same way. Benchmark: Cognitive reflection test. Answer: 5 cents: the bat costs $1.05, which is $1.00 more than the ball.

Check the rulespecimen · not scored

Which cards must you turn over to check whether the rule is broken?

(a) Rule

If a person is riding a scooter, they must wear a helmet. Each card describes one person: what they are doing on one side, what they wear on the other.

(b) Cards

Riding a scooter
Walking
Helmet
No helmet
Figure 3. A selection item in social-rule framing, which people solve far more often than the abstract version. Benchmark: Wason selection task. Answer: “Riding a scooter” and “No helmet”, the only two cards that could reveal a violation.
