Anchoring bias causes people to disproportionately weigh the first information they receive when making decisions. The status quo bias means decision makers prefer alternatives that maintain the current situation. Sunk cost bias leads us to make choices justifying past decisions, even if a change would now be better. Confirmation bias causes us to subconsciously decide what to do before objectively considering reasons. Framing effects demonstrate how the presentation of a problem influences choices. Overconfidence bias results in too narrow a range of predicted possibilities compared to reality.
