The conjunction fallacy is a cognitive bias in which people assume that specific conditions are more probable than general ones. This is often because they are using the representativeness heuristic, which involves making judgments based on how well the given information matches a particular prototype or stereotype. In this case, people may be more likely to choose a specific scenario that seems more representative of a complex event, even if it is less likely than an overall event that includes the specific scenario.
