Precision Is Not the Same as Accuracy
Extra decimal places can create false confidence.
The useful idea
- Understand
Precision describes how consistently or finely a value is expressed, while accuracy concerns closeness to the true value.
- Connect
A forecast can display several decimals even when its assumptions and inputs are highly uncertain.
- Apply
A range can communicate uncertainty more honestly than a single over-specific number.
Why this matters
Detailed presentation cannot repair weak measurement or uncertain evidence.
Try this
Ask for a reasonable range rather than one exact prediction.
