Hindsight bias. Hindsight bias, also known as the knew-it-all-along effect, is when people perceive events to be more predictable after they happen. With this bias, people overestimate their ability to predict an outcome beforehand, even though the information they had at the time would not have led them to the correct outcome. This type of bias happens often in sports and world affairs. Hindsight bias can lead to overconfidence in one’s ability to predict future outcomes.
