Heuristics- First what are heuristics? Research this type of heuristic and explain what it is. Base rate neglect is strongly related to sample size neglect. You would use a heuristic to make the decision quickly and without using much mental effort. However, sometimes these shortcuts send us off course. Did you know that our brain uses strategies to process information and draw conclusions? They are generally useful in that make decision-making more simple.
