Does the source exist?
Search the exact title, author, publisher, and date. Be cautious when a link redirects unexpectedly, the journal issue does not contain the article, or the cited organization has no record of the page.
Does it support this exact claim?
Match names, units, dates, populations, and conditions. A source about GPT-3 in 2020 does not support a claim that ChatGPT launched in 2020, even though the topics sound related.
Is it the strongest available source?
A social post or undated summary should not outweigh an official record or original study. Check whether the answer omitted a newer version, correction, retraction, or primary source.
What remains uncertain?
When evidence is mixed, say so. Responsible checking distinguishes contradiction from insufficient evidence instead of forcing every claim into true or false.
