Assignment 2: Discussion—Typical Reasoning
People often take shortcuts in problem solving and quickly arrive at answers. Known as heuristics, these shortcuts may increase the speed of decisions but may also decrease the accuracy of those decisions. The experiment used in this assignment deals with inaccurate decisions based on the conjunction fallacy, where people think the chance of two events happening at the same time is greater than just one event occurring. However, the chance of one event occurring is greater than two events occurring; hence, the fallacy.
