Commitment and consistency are psychological principles that describe how individuals align their actions with their beliefs and values. When people commit to a decision or a goal, they are more likely to follow through with actions that support that commitment. This behavior is often driven by a desire to appear reliable and trustworthy to themselves and others. Consistency reinforces commitment by encouraging individuals to maintain their choices over time. When someone consistently acts in accordance with their commitments, it strengthens their identity and self-perception. This principle is often utilized in areas like marketing and behavioral psychology, where maintaining a consistent message can influence consumer behavior and decision-making.
