Few mainstream I-638 news stories reported the facts that answer opponents

Five-second answer

True. Of 77 mainstream stories, 1 measured boys' athletic edge, 7 said the girl's own doctor verifies; 31 named Yes's funder. Our coding of 77 mainstream news stories, checked against the measure's filed text and its sources' own words, shows the facts that answer the No side's central arguments appeared in few stories, while the Yes side's funding appeared in 40% of them.

Common questions

Conclusion

Three facts answer the No campaign's central arguments directly, and none is in dispute. The measure's text says the check is done by the student's personal health care provider and that the provider may rely on genetic makeup or testosterone levels instead of anatomy. The measure bars male-born students only from female-only competition, so transgender girls can still play on boys' or open teams. And after puberty boys outperform girls by roughly 10-30% depending on the event, which is the reason the measure gives for a separate category. Yet in our coding of 77 mainstream news stories, 1 gave any measure of that performance gap (and only inside the Yes campaign's printed voter-guide statement), 7 said the girl's own provider does the check, and 7 said transgender girls can still play on boys' teams. Over the same months, 31 of the 77 told readers that Brian Heywood's Let's Go Washington funds the Yes side. The No side also had the last word in 55 stories to the Yes side's 11, and 31 stories repeated at least one No-side claim without context, against 14 for Yes-side claims. Our coding notes also record no story that mentioned that Washington rules let a parent change the sex designation on a minor's birth certificate (WAC 246-490-075), a fact that bears on the No side's argument about birth certificates. The finding is narrower than "the media was biased," and the rest of the evidence keeps it that way. Mainstream news quoted the Yes side first more often than the No side (44 to 24), and 27 of 77 stories did give the genetic and testosterone alternatives. Facts that answer the Yes side were also uncommon: only 2 of 77 reported that the American Academy of Pediatrics objected to being cited in the Yes pamphlet, and 5 that the sports-physical forms sent to schools have no sex field, while 10 repeated without context the Yes side's claim that physicals already document sex. (The history form that stays with the doctor does ask the family to report sex assigned at birth; no form has the provider verify it.) Mainstream errors ran both ways: KUOW told listeners the initiative offers "a visual genital exam" and that it was unclear who would conduct it, while KOMO said four times that the physical "already required by the state" proves biological sex, though a family's self-report proves nothing. Much of the pattern looks like thin, event-driven coverage that quoted campaigns rather than the text. Its effect still favored the No side, whose arguments depended on the text going unquoted. The best stories show it could be done in a sentence: the Seattle Times on Jan. 23, KOMO on Sept. 14 and Axios on Oct. 21 quoted the three bases. Conservative outlets show the mirror image, more strongly. Their 87 news stories quoted 1.9 Yes advocates and 0.6 No advocates per story, gave the Yes side the last word 57 times to 11, left the lead claim unanswered in 58, and never reported the pediatricians' objection or that the forms sent to schools have no sex field. Progressive and advocacy outlets were the most one-sided of all: none of their 29 news stories gave the performance gap or said transgender girls can still play on boys' teams, and every outlet-voice error we found in them favored the No side. We found no independent fact check of either campaign's claims, and every editorial board that took a position recommended No. We rate the claim True with moderate confidence. The counts are large and lopsided for the three central facts, and each coded story is published with its URL (one withheld because it contains a minor's name) so readers can recheck it. Confidence is moderate, not high, because the coding was done by one coder per outlet group with no blind second coder, the sample was found by search rather than drawn at random, several TV sites block automated reading, and TV stories were coded from their web text. A similar audit of I-645 coverage with the same design found 85-100% agreement between coders. The data shows what readers of these stories were told, not why reporters wrote them that way, and none of the errors we found was shown to be knowing.

How we checked

1. Defined the claim as a measurable statement about what mainstream news stories told readers, and fixed the codebook, outlet groups and twelve facts, six answering each side, before coding.
2. Collected 262 I-638 stories from about 50 outlets published Sept. 8, 2025 to Oct. 23, 2026, through outlet search pages, sitemaps, RSS, web search, archived and syndicated copies; 254 could be read.
3. Coded every story for sourcing, first and last word, rebuttals, campaign claims repeated with or without context, the twelve facts, loaded terms and factual errors in the outlet's own voice.
4. Checked every coded error against the filed initiative text, and re-read each quoted error and example on the live page on Oct. 23, 2026.
5. Searched PolitiFact, FactCheck.org, Snopes, Lead Stories, AP and local fact-check segments for checks of either campaign.
6. Computed every count from the published dataset with the published script, and recorded limits: one coder per group, a search-based sample, web text for TV, and outlets that block automated reading.

Editorial note: Scope: what Washington news and opinion outlets told readers about I-638 between Sept. 8, 2025 and Oct. 23, 2026, measured with one codebook applied to every outlet. It does not rate I-638, predict the vote, or judge reporters' intent. Outlet groups (mainstream, conservative, progressive/advocacy) were fixed by the audit design before coding. Minors are not named; where coded stories named student athletes, the dataset replaces the names with descriptions. The coded dataset, codebook and script are published so any reader can recode a story and check our counts. FactHub takes no position on I-638.

   • KUOW attributed a visual genital exam to the initiative; the text says reproductive anatomy and names no exam.

     What the source says

     According to the initiative, students would have several options to confirm their sex: a visual genital exam, a lab test to determine their genetic makeup, or an analysis of testosterone levels in the blood.

     Body, reporter's voice

   • KUOW said it was unclear who would conduct the exams; the text names the student's personal health care provider.

     What the source says

     But it’s unclear who would conduct the exams, when they should take place, or how to enforce the policy.

   Reliability: Seattle TV station; coded story. The sentence is in the reporter's voice and repeats the initiative's Sec. 1 finding as fact. A family's self-reported sex stays on the history form kept by the doctor, and no form has the provider verify sex, so no current physical proves it.

   • Qualifies: KOMO said existing state-required physicals prove biological sex, an error that favors the Yes side.

    • Qualifies: The Center Square said a doctor would check a box based on knowledge of the patient, which is not a basis the text lists.

      What the source says

      no genital exam is required under I-638, which would require a doctor to check a box on a sports physical form as to the gender of the student based on their knowledge and experience with the patient.
