Final answer:
Reasoning from a single case to an entire population is an example of a hasty generalization heuristic.
Step-by-step explanation:
Reasoning from a single case to an entire population is an example of a hasty generalization heuristic. This heuristic involves drawing broad conclusions based on insufficient evidence or a small sample size. For example, if someone assumes that all dogs are friendly because they met one friendly dog, they are using a hasty generalization heuristic. It is important to gather enough evidence from a representative sample before making generalizations about a population.
