Trust in scientists is a communicative construct shaped by public perception of scientists. Using network psychometrics on responses from 71,922 individuals in 68 countries, we model trust as an interconnected community system of attitudes and beliefs. Sincerity emerges as the most central node, linking perceptions of competence, integrity, and goodwill. This dynamic structure challenges reflective latent models and emphasizes trust as a product of message framing and credibility cues. Our findings inform science communication theory by reframing trust as an emergent network and offer practical guidance for communicators seeking to design inclusive, trust-enhancing strategies across diverse sociocultural contexts.
