The correct answer is availability
The availability heuristic is a brain process, in which the human mind defines the probability of an event happening based on how easily it remembers a similar event to have happened in the past.
It is a mechanism developed since primitive times, in which man lived in the midst of wild nature and needing possibilities was not an exact science.
In modern times, even, the heuristic of availability also arises in the face of issues of difficult immediate precision.
