Question

Principle: The Dunning-Kruger effect is a cognitive bias wherein individuals with low ability at a task overestimate their ability, while those with high ability may underestimate their competence.
Facts: Tutu, a new employee at a tech company, recently completed a basic coding course. Feeling confident, she frequently shares her opinions about software development with her colleagues, often dismissing their suggestions as unnecessary. Meanwhile, Saba, a senior developer with years of experience, is careful about her own ideas and often second-guesses her suggestions during team meetings.
Which of the following statements is true regarding Tutu and Saba’s behaviours?

• A. Tutu alone is exhibiting Dunning-Kruger effect
• B. Saba alone is exhibiting Dunning-Kruger effect
• C. Both Tutu and Saba are demonstrating Dunning-Kruger effect
• D. Neither Tutu nor Saba are demonstrating Dunning-Kruger effect

Answer 1

Answer: (A)

Tutu alone is exhibiting Dunning-Kruger effect

Answer 2

Tutu overestimates her ability, which is a key characteristic of the Dunning-Kruger effect. Saba , on the other hand, exhibits the opposite behavior of underestimating her abilities, which does not fit the definition of the effect.
