Answer:
The correct answer is: availability heuristic
Explanation:
The availability heuristic occurs when people judges the likelyhood of an event based on how easily an example of the event comes to mind. Under the availability heuristic, people tend to base their judgement on recent information that can be easily recalled, ignoring other relevant facts.
By basing their opinions on the latest news people can overestimate the likelyhood of an event, resulting in an important bias.
