Study Notes
Aim
- Investigated confirmation bias and logical reasoning errors.
- Focused on how heuristics affect decision-making in logical tasks.
Procedure
- Conducted as a lab experiment.
- Participants performed the Wason Selection Task involving cards displaying numbers and colors.
- Asked to determine which cards needed to be flipped to test the rule: "If a card shows an even number on one face, then its opposite face is red."
- Cards presented included: 3, 8, red, and brown.
Results
- Most participants incorrectly chose to flip the cards showing 8 and red.
- Less than 10% provided the correct selections: the 8 card and the brown card.
Implications
- Incorrect choices linked to heuristics, notably matching bias.
- Influenced by contextual wording like "even number" and "red."
- Quick and intuitive errors characterized as System 1 thinking.
- Task required deliberate analysis and logical reasoning, or System 2 thinking.
Ethical Considerations
- Study presented no major ethical issues.
Evaluation
- Limited details provided; further evaluation not specified.
