About this table

Description	Respondents in 25 EU countries (n = 36,452 with an answer of 40,500) read about an EU military intervention in a crisis to which zero or one cost clauses were added (soldiers at risk; national or pooled-budget financing; 2 x 3 factorial) and gave their support (0-1).

Notes

Conjoint table (irw_conjoint_2). Factorial vignette, one per respondent (25 EU countries pooled): an EU military crisis intervention with or without a soldiers-at-risk clause and with national, pooled or no financing information; rating = support on a 5-point scale stored as 0-1 (higher = more support; wording not in the deposit). Levels are the authors' labels; clauses left out are (not shown). Respondents with no answer are omitted.

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