The tendency to retroactively misremember ones past attitudes beliefs and behaviours as being more consistent with current viewpoints than they actually were.
Why it matters: Helps explain why people deny having changed their minds even when evidence shows they have.

Record your current views regularly to create an anchor for future recall.
Real-world example

Biases are not character flaws. They are recurring patterns in how minds compress uncertainty, save energy, and narrate reality. Once you recognise the pattern, you can slow the decision down, test the assumption, and make space for a better explanation.
