Coded items by category and side favored

What this dataset measures

The Seattle Times is Washington's largest daily newspaper and ran more staff news stories on I-638 than any other Washington outlet. This release records each item a two-coder review and a red-team pass flagged as departing from the measure's text, official statistics, peer-reviewed research or the paper's own later reporting, so readers can check every item and every count.

   Reliability: News report. Washington's largest daily newspaper and the subject of this review. Its own published wording is the record being coded.

Limitations and reproducibility

Partially reproducible: Every coded item gives the story URL, the coded wording and what the record shows, so anyone can re-check each item and recount the tables. The coding judgments themselves (especially framing) cannot be recomputed mechanically. Pre-correction wording for three corrected items comes from Internet Archive captures or the paper's correction notes.

• Framing calls are judgments. Two independent coders and a red-team review reduce, but do not remove, the chance that another reader would code an item differently. Inter-coder agreement was not computed formally.
• Scope: 44 Seattle Times staff, partner and freelance news stories on I-638 or Washington trans athletes, January 2025 to October 30, 2026. Opinion pieces, letters and wire copy are excluded, so the 12-to-2 opinion-page balance against the measure is not counted here.
• Only items that depart from the record are listed. Accurate statements are not tallied, so the table measures the direction of errors and slanted framing, not their rate per sentence.
• Quotes the paper printed without checking are tallied separately as 'unchecked', because they are not the paper's own words. They split roughly evenly: 4 favored Yes and 3 favored No.
• Some pre-correction wording (for example the October 14, 2026 Camas story) comes from an Internet Archive capture and the paper's correction note, not from the current page.
• One story URL contains the name of a minor athlete; for that row (B7) the url field gives the section page instead.
• The Seattle Times was not asked to comment before publication.
