Proportionality Bias

Decision-Making and Judgment Biases

Proportionality bias, also called the major event or major cause heuristic, is the tendency to assume that a big event must have had a big cause. It is a cognitive bias that plays a role in why people find conspiracy theories appealing, since a large or shocking event can feel as though it needs an equally large explanation.
