Consistency Bias: Rewriting Our Past Selves

Consistency Bias is the tendency to falsely remember our past beliefs and attitudes as being more similar to our current beliefs than they actually were.

The Psychology Behind It

We have a need for cognitive consistency - contradictions are uncomfortable. To maintain a coherent self-narrative, we unconsciously revise our memory of past beliefs to align with current ones.

Real-World Examples

1. Political Views

People who change political parties often remember always having doubts about their former party, even if they were once passionate supporters.

2. Relationships

After a breakup, people remember having more doubts about the relationship than they actually had.

3. Career Choices

"I always knew I wanted to be a doctor" - but old journals show you considered many paths.

Consequences

  • False Narratives: Creating inaccurate life stories
  • Inability to Learn: Not recognizing how much you've changed
  • Judging Others: Expecting others to have always believed what they believe now

How to Mitigate It

  1. Keep Records: Journal your beliefs and decisions
  2. Acknowledge Change: Recognize that growth means changing your mind
  3. Be Humble: Accept that past-you was different

Conclusion

Consistency Bias makes us think we've always been who we are now. The truth is, we're constantly evolving.
