What Polls Can Tell Us—and What They Cannot

SEO title: What Polls Can Tell Us—and What They Cannot

Meta description: An explainer on sample size, margin of error, weighting, question wording and the difference between polls and predictions.

An explainer on sample size, margin of error, weighting, question wording and the difference between polls and predictions. This is an evergreen explanatory draft, not a breaking-news report. The newsroom should confirm that the linked guidance remains current and add date-specific context where needed before publication.

What readers should understand

Start with the primary source and identify exactly what it says. Check the publication or update date, scope and whether it applies nationally or only to a particular location or situation. Headlines and social posts can omit important qualifications.

Where rules or numbers are involved, link directly to the original data, policy or document. Clearly distinguish established facts from interpretation, allegations, forecasts and opinion. If a source does not support a claim, rewrite or remove the claim rather than stretching the evidence.

Practical takeaways

• Use official records or the responsible organization as the starting point.
• Cross-check important claims with a reputable independent source.
• Explain uncertainty and avoid unsupported guarantees.
• Update the article when the source changes and note meaningful corrections.
