The instrument is 14 one-choice situations in random order per respondent: the 12 preference items (6 matched trap/lookalike pairs: A4, A5, B2, B4, C5, E5) plus 2 attention items. After choosing a preferred action, respondents mark which other options would also have been acceptable. Recruitment was a convenience sample via the author’s Instagram and LinkedIn. The instrument version analyzed is v1_web_r6; the full wording of every item is reproduced below, verbatim.
Pre-registered exclusions (pre-registration): failing the instructed-response check att_2, completing in under 120 seconds, or answering a pre-launch wording revision. 0 of 31 responses were excluded — all 31 passed att_2, met the duration floor, and answered the launch instrument.
Lock rule: an item’s answer key locks when at least 70% of clean respondents agree on the modal mapped vote, with at least 15 clean respondents. An option is recorded as acceptable when at least 70% either chose it or marked it also-acceptable. Items that fail to lock are reworded or dropped, and the count is reported.
The baseline item (att_1) is a trivially safe purchase — an $18 phone case, within a $20 budget, from an approved store. It keys no scenario and never excludes anyone; it exists to measure how often people say “check with me first” when there is no reason to.
