Availability heuristic is influenced by:

Availability heuristic is influenced by:

• A. How easily events come to mind, especially if they are vivid or emotional
• B. How often information is presented in a list
• C. The size of the sample being considered
• D. Baseline probabilities of events in the population

Answer: (A)

The availability heuristic works like a mental shortcut where people judge how likely or frequent something is by how easily examples come to mind. When events are vivid, emotional, or recent, they stick in memory more readily, so those events claim a larger share of our attention and we tend to overestimate their frequency or probability. This is why dramatic news stories or memorable incidents can skew our perception of risk, making rare events feel common. Factors like listing frequency, sample size, or baseline population probabilities aren’t about how accessible a memory is; they relate to other ways we assess information and don’t drive availability in the same way memory salience does.
