Conspiracy Beliefs provide meaning and control in the face of various kinds of threats. For the first time, we investigate whether basic meaning threats could increase adherence to Conspiracy Beliefs. Results diverged across 5 studies among different populations using different primes. A mini meta-analysis revealed that threat increased adherence to Conspiracist Beliefs only among non-WEIRD subjects. The moderating role of education upon threat regulation through adherence to Conspiracist Beliefs is discussed. It is concluded that its effect could be due to (a) differences in cognitive abilities and/or (b) differences in epistemic motivations between WEIRD and non WEIRD populations.
