'Things are not what they seem to be' : a proposal for the spectrum approach to conspiracy beliefs

Objective: Conspiracy beliefs (also known as conspiracy theories) become more prominent at times of heightened uncertainty and inconsistent or conflicting explanations provided by the authorities for events like terrorist attacks or pandemics, such as COVID-19. This article aims to examine the relevance of conspiracy beliefs for psychiatry in the context of the dynamics of trust and mistrust. Conclusions: Conspiracy beliefs may be situated on a spectrum of mistrust-related phenomena, which extends from healthy scepticism to persecutory delusions. They can be conceptualised as unfounded and fixed beliefs held with strong conviction about harm inflicted by powerful groups on the community or another group of people, usually with preserved insight that these beliefs differ from those that most people have and with reasons for having such beliefs not necessarily being implausible. It is important for conspiracy beliefs to be distinguished from persecutory delusions.
