Hypotheses

Overall: H1a: Generally additive -> Higher Risk-perception for PMT than others (PMT > P, M, T, PM, MT, PT, PMT free) H1b: Toxicity centered -> Higher Risk-perception for toxicity than other Chemicals (T, TM, TP, PMT > M, P, PM, PMT free) Moderator: H2a: Correlation gender: higher risk perception for women (Finucane et al. 2004) H2b: Correlation education: higher risk perception for higher education (Rattay et al. 2021) H2c: Correlation knowledge: higher risk perception for more prior knowledge (Siegrist & Cvetkovich, 2000) H2d: Correlation trust and knowledge: correlation between trust and risk-perception, moderated by prior knowledge (low prior knowledge) (Siegrist & Cvetkovich, 2000) Mediator: H3a: Higher Risk perception for Toothpaste
