Rapidly diverging public trust in science in the United States.

Trust in science is crucial to resolving societal problems. Americans across political ideologies have high levels of trust in science-a stable pattern observed over the past 50 years. Yet, trust in science varies by individual and group characteristics and faces several threats, from political actors, increased political polarization, or global crises. We revisit historical trends of trust in science among Americans by political orientation. We find steadily diverging trends by political views since the 1990s, and a drastically and rapidly opening gap since 2018. Recent unprecedented changes are driven not only by decreases in trust among conservatives but also by increases among liberals. Existing theoretical accounts do not fully explain these patterns. Diverging attitudes toward the institution of science can diminish capacity for collective problem-solving, eroding the shared foundation for decision-making and political discourse.
