Choice Retention Bias
After choosing, memory quietly upgrades the chosen option and downgrades the rejected ones; you remember having had better reasons than you did, and you defend past choices with invented evidence.
An everyday example
Recalling the vendor you picked as having had the better price, when your own notes show otherwise.
What it can cost you
Sticking with past choices on falsified memory; being unable to learn from decisions you now misremember.
Warning signs
- My reasons seem better in hindsight.
- I cannot find the downside I must have seen.
One thing to do
Keep the comparison sheet you decided from; when re-deciding, reopen it instead of your memory.
