Consistency bias

Shane Parrish and Robert Cialdini discussed the consistency bias in the context of commitment and consistency principles. This bias reflects the human tendency to remain consistent with previous statements or actions, especially when they are public. Cialdini shared an example involving a restaurant owner who reduced no-shows by eliciting a commitment from customers when they made reservations. He emphasized that gaining a public, voluntary commitment significantly increases the likelihood of subsequent actions aligning with that commitment. This concept not only applies to consumer behavior but can also be effectively used in management and personal decision-making.

Cialdini also pointed out that being aware of this bias is crucial, as it can lead to adhering to outdated or incorrect decisions. He advises evaluating new information and considering whether it would have influenced the original decision, allowing individuals to adjust their views and actions appropriately rather than being blindly consistent 1.
