A practical map of official, corporate and specialist sources—and a method for checking each claim.
Focus on current, attributable evidence and connect every meaningful signal to a decision, a small test or a clearly owned watch item.
Start with primary sources
Regulators, company filings, official statistics, product documentation and direct announcements are usually the strongest sources for facts. Specialist media adds context, while social posts can be useful early signals rather than proof.
Match the source to the question
Use official statistics for market size, pricing pages for current packaging, app stores for product history, review platforms for recurring customer problems, and hiring pages for strategic direction.
Verify before acting
Check the publication date, original source and geographic scope. Look for independent confirmation when a claim could materially change spending or strategy.
- Who published it?
- When was it updated?
- Is it a fact, estimate or opinion?
- Does it apply to your market?
Create a traceable research habit
Save the URL, date and one-sentence implication. This makes your intelligence auditable and stops outdated claims from quietly becoming assumptions.
