Consumer perceptions and stated intentions following descriptions of cultured meat and microbial protein: an exploratory within-person survey in Poland

De-identified survey data, codebook, analysis scripts (R 4.5.0 and Python) and output files for the article "Consumer perceptions and stated intentions following descriptions of cultured meat and microbial protein: an exploratory within-person survey in Poland", submitted to Nutrients (MDPI). A quota-managed, non-probability SurvGo online panel of Polish adults (analytic sample n = 258; data collected on 20 April 2026) evaluated a description of cultured meat and then a description of microbial protein exemplified by Solein, in a fixed order. The deposit contains: coded item-level data and scale scores; the data dictionary and value labels; R scripts for the paired comparisons with Holm correction and participant-level bootstrap intervals, cumulative-link mixed models, correlations and HC3 regressions, confirmatory factor analyses (robust maximum likelihood and WLSMV), HTMT2 diagnostics and the prior-awareness models; Python scripts for the figures and for earlier exploratory calculations; the output files behind the numbers reported in the article; Tables 1-3 and Supplementary Tables S1-S13; and Figures 1-2. Reproduction copies and earlier exploratory outputs are not included but are recreated by the scripts. File checksums are listed in MANIFEST_SHA256.
