About this table

Notes

• Conjoint table (irw_conjoint). rating: 'To what extent is this candidate favorable as a [HoR/HoC] member?' 8-point scale, 1 = not favorable at all, 8 = very favorable (authors' translation of the Japanese item); single profile per task, 10 tasks per chamber, chamber block order randomized (trial_chamber; task = order shown, rebuilt from HOR_first as in the authors' code); half of respondents read a priming paragraph on the lower house's supremacy (trial_priming). Level probabilities follow real-world distributions (nonuniform); attribute order randomized per respondent (attrpos_). Hometown text keeps the template X (respondent's prefecture was inserted). N 2,267 matches the paper; inattentive respondents were removed by the authors before deposit.

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

Task order or profile position was rebuilt from row order; analyses of position or task order should leave it out.
