Left out – Feelings of social exclusion incite individuals with high conspiracy mentality to reject complex scientific messages
We investigated linguistic factors that affect peoples’ trust in science and their commitment to follow evidence-based recommendations, crucial for limiting the spread of COVID-19. In an experiment (N = 617), we examined whether complex (vs. simple) scientific statements on mask-wearing can decrease trust in information and its sources, and hinder adherence to behavioral measures. In line with former research on social exclusion through complex language, we also examined whether complexity effects are mediated via feelings of exclusion. Results indicate that negative effects of text complexity were present, but only for participants with a strong conspiracy mentality. This finding informs how to decrease distrust in science among individuals with high conspiracy mentality, a population commonly known for its rejection of scientific evidence.
