A practical way to think about source quality in public business research

Not all public sources deserve the same amount of trust, and “public” does not automatically mean “authoritative.”

A useful way to think about source quality is to ask what relationship the source has to the fact you are trying to establish.

An official filing may be close to the source for a legal entity name. A company website may be better for its current product positioning. A government statistical dataset may be excellent for market context but poor for confirming whether one specific business is still operating from a particular address.

The source should fit the question.

Freshness matters too. An otherwise reputable directory can still be wrong if its information has not been updated. A company page can also be stale. Even official records can describe a past reporting period rather than current operating conditions.

Then there is independence. Five websites repeating the same incorrect record do not necessarily provide five pieces of evidence. They may all be copying the same original source.

That is why source count and source quality are different ideas.

Good public research usually combines authority, recency, relevance, and enough source context to understand what the evidence actually supports.

The goal is not to create a universal ranking of websites. It is to choose evidence that is appropriate for the claim being made.

A strong source is not merely reputable. It is useful for the specific question in front of you.
