Notes

Conjoint table (irw_conjoint). choice = which of the two news items the respondent would choose to read (paraphrase; wording not in the deposit), forced choice, no opt-out, 12 tasks per respondent. Partisans only (cov_dem / cov_rep). Two attributes: headline text and outlet; the two items share a topic in about 9% of tasks and an outlet in about 34%, with no restriction documented. Qualtrics response ids re-keyed; the author's derived topic and friendly/unfriendly-source dummies dropped.

These notes describe the source data, which the IRW reproduces as released. All notes are listed on the Data Notes page.
