ニューヨーク州立大学バッファロー校(University at Buffalo)の研究によると、ソーシャルメディアの利用頻度が高い人ほど気候変動に対する不安(climate anxiety)や「気候破滅主義(climate doom)」を感じやすいことが判明した。2024年に米国成人1,400人を対象に実施した調査では、TikTokやSnapchatの利用者で特に強い相関が見られた。また、「気候破滅主義」を持つ人はサボタージュやハッキングなど急進的行動を支持する傾向がある一方、権威主義的政策への支持とは無関係だった。研究者は、アルゴリズムがリスク認知を極端化させる可能性を指摘し、効果的な情報設計と心理的支援策の必要性を強調した。成果は『Climatic Change』誌に掲載。

気候不安とSNS使用の関連性を解明(Study links climate anxiety to social media use)

Abstract

Climate anxiety and climate distress are receiving growing attention as psychological conditions that deserve individual interventions, but potential social and structural drivers of these conditions warrant further study. Is there a relationship between climate anxiety and climate doom, and social media use? If so, what are the collective social and political implications of this? These questions matter for developing effective interventions in climate anxiety and climate doom on the individual, psychological level as well as the broader social level. If climate doom is related to support for authoritarian policies or extremist action, this presents an understudied risk for how we communicate about climate. We explore these questions in a survey of US adults (N = 1,400) and find that social media use correlates with increased climate distress and climate doom. We find that climate doom, but not climate distress, is associated with support for radical actions such as sabotage, threatening CEOs, and hacking fossil fuel cyberinfrastructure. Together, these results suggest a need for further research into both the role of social media in climate anxiety interventions and the broader social and political implications of climate doom.
