How scientists talk about their own mistakes may matter as much as the science itself — particularly for audiences who felt dismissed during the pandemic. As public trust in scientific institutions remains fractured along political lines, this research offers an evidence-based communication framework with real implications for how health authorities navigate the next crisis.
Across four pre-registered experimental studies conducted in 2025 with 1,441 U.S. participants, researchers tested two distinct scientist communication styles: an authoritative framing that defended institutional decisions, minimized errors, and attributed misinformation selectively, versus an accountability-embracing framing that acknowledged mistakes, engaged with critics, and recognized misinformation across ideological lines. Participants exposed to the accountability-embracing scientist rated that scientist higher on generalized trust, prestige, and willingness to fund or platform their work. The effect was particularly pronounced among political conservatives — the demographic that exhibited the steepest decline in science engagement during COVID-19.
This work sits at an important intersection of science communication research, political psychology, and public health. The two-sided messaging framework used here has decades of support in persuasion research — audiences tend to find sources more credible when they acknowledge limitations rather than project certainty. What is novel is applying this lens specifically to post-crisis repair of science-public relations, and demonstrating measurable differences in actionable engagement indicators like funding support, not just attitudinal ones. The study's experimental design strengthens causal inference, though the sample is limited to a single national context and simulated communication scenarios. Whether real-world scientists adopting this posture would produce equivalent trust gains — especially against the noise of social media — remains untested. Still, for science communicators and public health institutions rebuilding credibility, these findings represent a meaningful, practically actionable signal: intellectual humility is not a weakness but a trust-building asset.
