Illusory Correlations: Definition and Examples in AP Psychology

📚 Quick Study Guide

• 🧠 Illusory correlations are perceived relationships between two things, even when no actual relationship exists.
• 📈 They often arise from the human tendency to seek patterns and confirm pre-existing beliefs.
• 📰 Confirmation bias plays a big role; we notice and remember instances that support our beliefs and ignore those that don't.
• 💡 Illusory correlations can lead to stereotypes and prejudiced attitudes.
• 📊 Examples include believing that all members of a certain group share the same traits or linking unrelated events together.
• 🧪 Research methods like correlational studies help identify (or disprove) illusory correlations.
• 📝 Be careful not to confuse correlation with causation! Just because two things appear related doesn't mean one causes the other.
