Answer:
the the representativeness heuristic
Explanation:
The representativeness heuristic was proposed by psychologists Amos Tversky and Daniel Kahneman in the early 1970s. This heuristic is used in making judgements or rather "near approximations" under uncertainty. it works by judging an event based on how similar it is to a parent event/population or a past event that looks just like it. This heuristic is however prone to errors and therefore is a bias since events may be wrongly judged even they appear similar to a parent event
