Recency Bias

The latest information is remembered best and weighted most; the last quarter, the last meeting, the last thing the salesperson said.

An everyday example

Choosing the vendor whose pitch you heard most recently; forecasting from the last three months.

What it can cost you

Decisions shaped by order and timing rather than evidence; counterparts who arrange to speak last.

Warning signs

  • The last one seems best.
  • I remember the recent one in detail and the earlier ones vaguely.

One thing to do

Write your assessment of each option immediately after seeing it; decide from the notes, not from memory.

Is this happening to you right now?
