How to use filters without misleading yourself
Filters are powerful, but narrow slices can produce overconfident conclusions.
The risk with filters
The narrower your filters, the smaller and more specific the story becomes. A result inside one model, one country, one persona, and one short date range is useful — but it should not be treated as the whole account story.
Best filtering approach
Start broad. Then narrow down one dimension at a time. This makes it easier to see which filter is actually changing the outcome.
What to avoid
Do not compare two highly filtered views and treat them like a full-market truth. Always remember that the filters define the story you are reading.
Good operating rule
Use filtered views for diagnosis and comparison. Return to a broader view before drawing strategic conclusions.
