This paper explores the epistemic implications of endorsing a specific category of conspiracy theories, which I term “toxic conspiracy theories” (following Basham, 2018). I contend that these theories exert a profound and distinctive impact on our belief system, not only shaping perspectives on the specific events they are purported to explain, but also influencing our broader understanding of sociopolitical reality. I delineate a surprising result of this doxastically encompassing nature of toxic conspiracy theories: if some toxic conspiracy theory is true, then a belief in a false one can be remarkably illuminating. Consequently, adherents of toxic conspiracy theories may, contrary to prevailing opinion, possess a more astute grasp of sociopolitical realities than their counterparts who eschew such conspiratorial narratives. I then move on to address an objection suggesting that toxic conspiracy theories are so overwhelmingly unlikely to render the central argument a mere academic exercise. In response I draw on various ‘particularist’ arguments to the contrary and further argue that the unlikelihood of toxic conspiracy theories cannot be determined without engagement with some foundational questions regarding the nature and integrity of our democratic institutions.
