tldr: we found very limited evidence for distress subsequently increasing belief in conspiracy theories using a longitudinal survey sampling participants 7 times over ~6 months - and no evidence for belief in conspiracy theories worsening distress over time
New research challenges the idea of a ‘vicious cycle’ between psychological distress and conspiracy beliefs
One prominent theory says conspiracy beliefs are triggered by elevated distress. But a new study finds limited evidence to support this claim.

Conspiracies emerge in the wake of high-profile events, but you can’t debunk them with evidence because little yet exists. Does this mean LLMs can’t debunk conspiracies during ongoing events? No!
