Walter's mistake is an example of the conjunction fallacy, which refers to the tendency to overestimate the likelihood of a joint event occurring, even when it is less likely than the individual events occurring separately. This is a common cognitive bias that can lead to faulty reasoning and decision-making. The framing effect refers to how a choice is presented, mental set refers to a tendency to approach a problem in a certain way due to past experience, and belief perseverance refers to the tendency to maintain a belief even in the face of contradictory evidence. These concepts are not directly relevant to Walter's mistake.
