Executive summary

Major, long-standing fact‑checking organizations — including PolitiFact, FactCheck.org, The Washington Post’s Fact Checker, Snopes and international outlets such as AAP and Logically — have the institutional capacity and documented methodologies to investigate viral social‑media claims about politicians; however, the sources provided do not contain specific examples of these organizations fact‑checking politicians’ IQ claims, so the following reconstructs which organizations would typically examine such claims and how they would do it based on documented practices [1] [2] [3] [4].

1. Who the players are — the usual suspects that monitor viral political claims

PolitiFact, FactCheck.org and The Washington Post’s Fact Checker are repeatedly cited as leading U.S. political fact‑checkers who evaluate claims made by public figures and viral social posts, while Snopes, Logically and the Australian Associated Press FactCheck (AAP) are examples of other organizations studied in comparative research on fact‑checking activity [1] [2] [3] [4].

2. What kinds of claims these organizations take on — including viral social posts

These organizations focus on political statements and viral stories on social media: PolitiFact explicitly investigates statements by political figures and viral social‑media stories, and academic datasets used to study fact‑checking rely heavily on PolitiFact’s catalog of verified statements [1]. Comparative research likewise shows fact‑checkers select a mix of politicians’ assertions and widely shared rumors, indicating that a viral claim about a politician’s IQ would fall within their remit [3] [4].

3. Core investigative methods — sourcing, contacting claimants, and using original data

Traditional fact‑check methodologies include reaching out to the person or organization responsible for the claim, consulting raw data and original sources, and using search engines and archival material to trace the claim’s provenance; the Washington Post’s Fact Checker, PolitiFact, and FactCheck.org all follow variants of this method in their reporting [2]. These outlets publicly describe practices such as contacting sources, checking primary documents and datasets, and situating a claim within its broader factual context [2].

4. Rating systems and transparency — how verdicts are framed

Major U.S. fact‑checkers use structured verdict systems to communicate findings: PolitiFact’s Truth‑O‑Meter and the Washington Post’s Pinocchio scale are cited conventions that translate research into reader‑friendly judgments, and studies show these structured labels are part of what gives fact‑checks appeal and clarity [5] [2] [6]. Comparative research also points to the value of multiple organizations corroborating a finding to increase reliability [3].

5. Computational and crowdsourced tools that support investigations

Fact‑checking is increasingly augmented by automated and crowdsourced tools: ClaimBuster and other NLP models can flag factual claims for human review, Emergent.Info staff track and verify rumors, and platforms like Hoaxy visualize claim diffusion — all tools that fact‑checkers or researchers may use to detect and prioritize viral claims for investigation [7]. Academic and platform collaborations (e.g., ClaimReview metadata) are also used to structure and share findings across organizations [8] [7].

6. Limits of the public record — what the provided sources do not show

None of the supplied sources document a specific case where these organizations fact‑checked a viral claim about a politician’s IQ; the literature and guides describe general practices and sampled studies of political claims, but concrete examples of IQ‑score debunks are absent from the provided reporting, so any statement that a given outlet did or did not evaluate a particular IQ claim would go beyond these sources [1] [3] [4].

7. Conflicts, agendas and disagreement among fact‑checkers

Scholarly work shows fact‑checkers vary in claim selection and that disagreement is common when language is ambiguous; meta‑studies find high agreement in many cases but also emphasize selection differences and perceptions of bias, meaning that investigations into something as interpretive as “IQ” could be contested on method and framing by different outlets [3] [6] [9]. Readers should therefore expect methodological debate — for example over what counts as authoritative testing data or whether an offhand social‑media post qualifies as a verifiable factual claim.

8. Practical takeaway — how an IQ claim would likely be evaluated

Based on documented methods, an investigation into a viral IQ claim about a politician would typically involve tracing the original post, seeking primary documents (test results, official statements), contacting the subject or their representative, consulting expert sources on IQ measurement, and then issuing a coded verdict using an established rating system; computational tools might be used to detect spread and prioritize the claim for human fact‑checkers [2] [7] [5]. The provided sources support these methodological steps, but they do not provide a recorded instance specific to IQ claims [1] [3].
