15,898 rated or chosen profiles from 1,996 respondents, in up to 5 tasks of 2 profiles varying on 7 attributes.
| Description | US Prolific respondents (n=1,996, March 2024) chose between pairs of hypothetical newly elected state legislatures (members' occupational class, session length, staff, salary, party control, bill limits, calendar posting) on three questions: which benefits society, which benefits people like you, and a third whose wording is not deposited. |

| Randomization restrictions | observed in the data (not documented by the source): session 'Unlimited' never occurs with salary $0k (0 of 15,898 profiles; every other session x salary cell ~1,000-1,130); this prohibited pair explains the lower shares of salary $0k and session Unlimited |
| Task order | recorded in the deposit |
| Profile position | recorded in the deposit |
Because the attribute levels were not randomized independently, an estimator has to account for the restriction; a plain difference in means across levels can mislead.
