Which statement best describes availability bias and a common mitigation strategy?

• A. Availability bias relies on easily recalled information.
• B. It fixates on initial values.
• C. It seeks information that confirms beliefs.
• D. It overweighs recent data.

Answer: (A)

Availability bias occurs when judgments are guided more by information that’s easy to recall or appears vividly, rather than by all relevant data. Because what comes to mind quickly feels representative, people overemphasize those memories when making decisions, even if they’re not the most informative sample. A common way to counter this is to use a deliberate, structured approach to information gathering—seek data from diverse sources, rely on objective metrics, and use checklists or decision rules that require considering information beyond what is most readily recalled. This helps balance intuition with evidence and reduces the influence of memorable but unrepresentative instances.

That description matches the idea that availability bias relies on easily recalled information. The other statements point to different biases—fixating on initial values describes anchoring, seeking information that confirms beliefs describes confirmation bias, and overweighing recent data describes recency bias—so they don’t capture the core of availability bias.
