Concerns about existential threats ranging from climate change to artificial intelligence have become increasingly prominent in public discourse, creating what some characterize as a pervasive sense of impending doom. The Doomsday Clock, maintained by the Bulletin of the Atomic Scientists since 1947, serves as a symbolic representation of humanity’s proximity to catastrophe, currently positioned at 85 seconds to midnight.
Communicators attempting to address these challenges occupy different positions on how best to inspire action. Some activists and researchers, such as former Anthropic researcher Jacob Coxon, emphasize the severity of existential risks to mobilize public concern. Critics counter that such messaging may be exaggerated or counterproductive. A third perspective acknowledges genuine risks while questioning whether fear-based appeals effectively drive behavioral change.
Psychological research on persuasion demonstrates that messaging can influence public opinion, but with important limitations. An analysis of 22,743 headline experiments found that each additional negative word increased click-through rates by 2.3%, reflecting what psychologists term negativity bias. However, a large-scale study involving 59,440 participants across 63 countries tested different climate-related messages and their effects on both belief formation and actual mitigation behavior.
The research revealed a significant disconnect: a doom-laden message about catastrophic climate consequences proved most effective at generating social media engagement but was the least successful at motivating concrete action such as tree-planting or policy support. By contrast, a message emphasizing scientific consensus—that 99% of climate scientists agree the Earth is warming due to human activity—proved more effective across most outcomes measured, conveying factual information in measured terms.
The findings suggest that while honest communication about risks remains essential, the manner of presentation substantially influences whether people respond with constructive action or withdrawal. A modern information ecosystem that rewards negativity may inadvertently undermine the behavioral change necessary to address the very threats being highlighted.
