Lead with statistics, then interpret with narrative — not the reverse
Use the base rate as your anchor, then adjust for your specific situation — not the other way around.
Key takeaways
- What it is: Use the base rate as your anchor, then adjust for your specific situation — not the other way around.
- Why it works: When people start with a vivid story or personal narrative and then consult statistics, the narrative dominates — the statistic is assimilated into an already-formed impression. When they start with the statistic and then ask how the specific situation differs, the statistic serves as a genuine anchor. The order of information matters because of anchoring and confirmation bias: whichever value is established first pulls subsequent processing toward it.
- Evidence: Backed by observational / correlational evidence.
- Avoid: Consulting statistics after narrative as a check rather than as the anchor, so the narrative already frames what the statistic will mean.
Why it works
When people start with a vivid story or personal narrative and then consult statistics, the narrative dominates — the statistic is assimilated into an already-formed impression. When they start with the statistic and then ask how the specific situation differs, the statistic serves as a genuine anchor. The order of information matters because of anchoring and confirmation bias: whichever value is established first pulls subsequent processing toward it.
How to do it
- 1For any probability estimate you are forming, find the relevant statistic before reading or forming a narrative.
- 2Start from that number: "The base rate is X%. Now, what features of my situation move this up or down?"
- 3Require yourself to state the base rate before sharing your personal estimate in any discussion.
- 4When someone leads with an anecdote, ask for the base rate before responding to the story.
What the evidence says
ObservationalAnchoring research (Tversky & Kahneman) shows that the first value encountered pulls subsequent estimates toward it. Starting with an accurate base rate anchors in the right direction; starting with a vivid narrative anchors on its implied (often distorted) frequency.
Honest caveat: Even starting with an accurate base rate does not fully prevent narrative from influencing the final estimate; the effect is reduced, not eliminated.

Common mistake
Consulting statistics after narrative as a check rather than as the anchor, so the narrative already frames what the statistic will mean.
IX Coach always surfaces the relevant base rate before asking you to interpret your situation’s specific features, establishing the statistic as the anchor for the analysis.
