How do you check whether an expert’s credentials fit a particular claim?
Identify the person, their actual field and the precise claim being made. Find a checkable original work. Credentials provide context, but they do not replace evidence for the statement itself.
Separate the title from the claim
- Write the sentence you need to verify.
- Find the author's institutional or work page.
- Check whether that work addresses the same question. A designer can describe a personal sketching process without that credential proving the process makes everyone more intelligent.
Keep a traceable assessment
Record whether you read an interview, personal essay, abstract or complete paper. If the quotation cannot be located, mark it unverified instead of repeating it as a research conclusion. An unfamiliar field can still provide an interesting question; the wording of your citation should reflect what the source actually supports.
A worksheet you can use
Claim: __. Person and field: __. Original URL: __. Reading scope: __. Supported point: __. Unknown: __.
Are authors without degrees unhelpful?
No. Practical experience can be valuable. Present experience as experience rather than automatically making it a universal scientific finding.
Evidence and scope
This is not a judgement of a person's formal qualifications. Relevance and evidence require separate consideration.
