2. Hindsight bias

3. Halo effect

Examples

A. After hearing that a student is very talented at sport, a teacher assumes the student will also be excellent at every subject.

B. A person only reads articles that support their belief and ignores reliable information that disagrees with it.

C. A manager assumes an older worker will struggle to learn new technology.

D. After a team loses, someone says, “I knew they would lose all along,” even though they had predicted a win.

E. A shopper believes a product is perfect because the advertisement shows only its most successful users.

F. A coach focuses only on the athletes who succeeded and ignores those who trained just as hard but did not win.

7. Choose one matched example and explain why it shows that type of bias.

8. Write your own example of one type of bias.
