The problem
Normative Reasoning Accuracy erodes when it is left to instinct instead of method.
You were taught the moves piecemeal, never the whole model.

Step 1 of 5 · Task Design and Framing Conditions
The Wason selection task's failure rate collapses when the same logic is framed as checking whether people are old enough to drink, proving content, not structure, drives performance.
Misconception
Practitioners assume that if two problems share the same logical structure, they are equivalent tests of reasoning ability.
Reality
Logically identical problems produce wildly different success rates depending on whether they are couched abstractly or in familiar content, and whether they invoke social rules like permission and obligation — content does the reasoning that abstract form cannot.

Step 2 of 5 · General Intelligence (g)
g is the shared variance across diverse cognitive tasks, tightly bound to working-memory capacity.
Misconception
That a high IQ makes someone immune to reasoning biases and logical errors.
Reality
g predicts how quickly and accurately you handle tasks with a clear correct answer, but high-g individuals still commit the same normative violations — belief bias, base-rate neglect — unless they are cued to engage deliberate processing.

Step 3 of 5 · Working Memory Capacity
Working memory holds only a handful of chunks at once, so any reasoning task that requires tracking more elements than that will fail unless you offload.
Misconception
People assume working memory capacity is fixed intelligence that you either have or lack, so a poor performer is simply not smart enough.
Reality
Capacity is a bottleneck on how much you can hold live at one moment, not a ceiling on competence; experts route around it by chunking information and offloading onto the page, so measured span is malleable in effect even when raw span is stable.

Step 4 of 5 · Rational Thinking Disposition
Intelligence sets the ceiling on reasoning quality; disposition determines whether you reach it.
Misconception
Practitioners assume that smart people reason well, treating intelligence and the willingness to reason as the same trait.
Reality
Cognitive-style scales measure a disposition that is only weakly correlated with IQ; plenty of highly intelligent people are 'cognitive misers' who accept the first plausible answer, and plenty of modest reasoners habitually recheck theirs.

Step 5 of 5 · Prior Knowledge and Belief
Prior belief can substitute for logical analysis without your awareness, especially when the conclusion is emotionally or ideologically loaded.
Misconception
Reasoners believe they evaluate an argument's logic separately from whether they agree with its conclusion.
Reality
Belief bias shows the two are entangled: people routinely judge valid-but-unbelievable syllogisms invalid and invalid-but-believable ones valid, so the conclusion's plausibility leaks into the assessment of its logical form.

The cheat sheet
- Task Design and Framing ConditionsThe Wason selection task's failure rate collapses when the same logic is framed as checking whether people are old enough to drink, proving content, not structure, drives performance.
- General Intelligence (g)g is the shared variance across diverse cognitive tasks, tightly bound to working-memory capacity.
- Working Memory CapacityWorking memory holds only a handful of chunks at once, so any reasoning task that requires tracking more elements than that will fail unless you offload.
- Rational Thinking DispositionIntelligence sets the ceiling on reasoning quality; disposition determines whether you reach it.
- Prior Knowledge and BeliefPrior belief can substitute for logical analysis without your awareness, especially when the conclusion is emotionally or ideologically loaded.
- Type 1 (Intuitive) ProcessingIntuition is fast associative retrieval, not a lesser form of thinking—it can outperform analysis in high-validity domains.
- Type 2 (Reflective) ProcessingReflective reasoning is optional and effortful—its main failure mode is never being engaged at all.
- Cognitive BiasBiases are systematic and directional, which is what makes them dangerous and also what makes them predictable.
