For a long time, conspiracy theories have received relatively little scholarly attention in psychology or political science but seemed like eccentric quirks of only a few. Since increased visibility of conspiracy beliefs around 9/11, election fraud, and most recently the COVID-19 pandemic in 2020 (e.g., the concerted spread of #filmyourhospital, Gruzd & Mai, 2020), this has drastically changed. At first glance, these different conspiracy beliefs appear to be diverse regarding the range of topics covered (e.g., terrorism, democratic processes, health crises), the political orientations endorsing them (e.g., blaming the Republican Bush administration for the 9/11 inside job vs. blaming Democrats to 'steal' the US-election in 2020) as well as their likelihood from scientific perspectives. Some narratives are proven to be very unlikely (Grimes, 2016) while others are more plausible and connected to rational skepticism (Stojanov & Halberstadt, 2019).A closer look, however, reveals shared principles: Conspiracy theories (defined as ' attempts to explain the ultimate causes of significant social and political events and circumstances with claims of secret plots by two or more powerful actors ', Douglas et al., 2019, p. 4) express per definition inter alia mistrust in authorities and powerful groups and the motivation to find explanations (for a critical discussion of the assumption that conspiracy theories only target powerful actors, see Nera et al., 2021). Consequently, research elaborated the empirical commonality that people who believe in one conspiracy also tend to believe in others (Goertzel, 1994) raising the question if this finding can be attributed to a homogenous construct such as a generalized political attitude (Imhoff & Bruder, 2014) or a monological belief system (Goertzel, 1994). But the existence of a general mindset remains a controversial issue including calls for a more differentiated perspective (Hagen, 2020;Pierre, 2020;Sutton & Douglas, 2020b). The aim of the present studies is to provide further empirical evidence addressing the question of consistency of conspiracism by examining latent response profiles of participants.
The Conspiracy MindsetThe assumption of a general mindset relies basically on the robust empirical evidence that conspiracy items are substantially intercorrelated (Goertzel, 1994;Swami et al., 2010;Swami et al., 2011), even when the narratives are contradictory (Miller, 2020;Wood et al., 2012). It suggests that the degree of agreement on various items has common grounds explaining the connections; e.g., as a
