Counterintuitive Pseudoscience Propagates by Exploiting the Mind's Communication Evaluation Mechanisms.

Epidemiological models of culture posit that the prevalence of a belief depends in part on the fit between that belief and intuitions generated by the mind's reliably developing architecture. Application of such models to pseudoscience suggests that one route via which these beliefs gain widespread appeal stems from their compatibility with these intuitions. For example, anti-vaccination beliefs are readily adopted because they cohere with intuitions about the threat of contagion. However, other varieties of popular pseudoscience such as astrology and parapsychology contain content that violates intuitions held about objects and people. Here, we propose a pathway by which "counterintuitive pseudoscience" may spread and receive endorsement. Drawing on recent empirical evidence, we suggest that counterintuitive pseudoscience triggers the mind's communication evaluation mechanisms. These mechanisms are hypothesized to quarantine epistemically-suspect information including counterintuitive pseudoscientific concepts. As a consequence, these beliefs may not immediately update conflicting intuitions and may be largely restricted from influencing behavior. Nonetheless, counterintuitive pseudoscientific concepts, when in combination with intuitively appealing content, may differentially draw attention and memory. People may also be motivated to seek further information about these concepts, including by asking others, in an attempt to reconcile them with prior beliefs. This in turn promotes the re-transmission of these ideas. We discuss how, during this information-search, support for counterintuitive pseudoscience may come from deference to apparently authoritative sources, reasoned arguments, and the functional outcomes of these beliefs. Ultimately, these factors promote the cultural success of counterintuitive pseudoscience but explicit endorsement of these concepts may not entail tacit commitment.

She told me about a singing cactus: Counterintuitive concepts are more accurately attributed to their speakers than ordinary concepts.

Communication is central to human life, yet it leaves humans vulnerable to misinformation and manipulation. Humans have therefore evolved a suite of psychological mechanisms for the evaluation of speakers and their messages. Here, we test a key hypothesized function of these "epistemic vigilance" mechanisms: the selective remembering of links between speakers and messages that are inconsistent with preexisting beliefs. Across four experiments, participants (N = 707) read stories associated with different contexts, with each story containing concepts that violate core knowledge intuitions ("counterintuitive concepts") and ordinary concepts. Experiment 1 revealed that after a brief distractor (2 min) participants more accurately attributed counterintuitive concepts to their speakers than ordinary concepts. Experiments 2a and 2b replicated this finding and found that this attribution accuracy advantage also extended to counterintuitive versus ordinary concepts associated with other contextual details-places and dates. Experiment 3 then tested whether this attribution accuracy advantage was more stable over time for speakers than for places. After a short distractor (20 min), there was a counterintuitive versus ordinary concept attribution accuracy advantage for both speakers and places. However, when participants were tested again after a long delay (48 hr), this attribution accuracy advantage more than doubled for speakers but disappeared entirely for places. We discuss the implications of these findings to the set of psychological mechanisms theorized to monitor and evaluate communication to guard our database of beliefs about the world.

The Embodied God: Core Intuitions About Person Physicality Coexist and Interfere With Acquired Christian Beliefs About God, the Holy Spirit, and Jesus.

Why are disembodied extraordinary beings like gods and spirits prevalent in past and present theologies? Under the intuitive Cartesian dualism hypothesis, this is because it is natural to conceptualize of minds as separate from bodies; under the counterintuitiveness hypothesis, this is because beliefs in minds without bodies are unnatural-such beliefs violate core knowledge intuitions about person physicality and consequently have a social transmission advantage. We report on a critical test of these contrasting hypotheses. Prior research found that among adult Christian religious adherents, intuitions about person psychology coexist and interfere with theological conceptualizations of God (e.g., infallibility). Here, we use a sentence verification paradigm where participants are asked to evaluate as true or false statements on which core knowledge intuitions about person physicality and psychology and Christian theology about God are inconsistent (true on one and false on the other) versus consistent (both true or both false). We find, as predicted by the counterintuitiveness hypothesis but not the Cartesian dualism hypothesis, that Christian religious adherents show worse performance (lower accuracy and slower response time) on statements where Christian theological doctrines about God's physicality (e.g., incorporeality, omnipresence) conflict with intuitions about person physicality. We find these effects for other extraordinary beings in Christianity-the Holy Spirit and Jesus-but not for an ordinary being (priest). We conclude that it is unintuitive to conceptualize extraordinary beings as disembodied, and that this, rather than inherent Cartesian dualism, may explain the prevalence of beliefs in such beings.

Representational coexistence in the God concept: Core knowledge intuitions of God as a person are not revised by Christian theology despite lifelong experience.

Previous research has shown that in the minds of young adult religious adherents, acquired theology about the extraordinary characteristics of God (e.g., omniscience) coexists with, rather than replaces, an initial concept of God formed by co-option of the person concept. We tested the hypothesis that representational coexistence holds even after extensive experience with Christian theology, as indexed by age. Christian religious adherents ranging in age from 18 to 87 years were asked to evaluate as true or false statements on which core knowledge intuitions about persons and Christian theology about God were consistent (both true or both false) or inconsistent (true on one and false on the other). Results showed, across adulthood, more theological errors in evaluating inconsistent versus consistent statements. Older adults also exhibited slower response times to inconsistent versus consistent statements. These findings show that despite extensive experience, indeed a lifetime of experience for some participants, the Christian theological God concept does not separate from the initial person concept from which it is formed. In fact, behavioral signatures of representational coexistence were not attenuated by experience. We discuss the broader implications of these findings to the acquisition of evolutionarily new concepts.

Core Intuitions About Persons Coexist and Interfere With Acquired Christian Beliefs About God.

This study tested the hypothesis that in the minds of adult religious adherents, acquired beliefs about the extraordinary characteristics of God coexist with, rather than replace, an initial representation of God formed by co-option of the evolved person concept. In three experiments, Christian religious adherents were asked to evaluate a series of statements for which core intuitions about persons and acquired Christian beliefs about God were consistent (i.e., true according to both [e.g., "God has beliefs that are true"] or false according to both [e.g., "All beliefs God has are false"]) or inconsistent (i.e., true on intuition but false theologically [e.g., "God has beliefs that are false"] or false on intuition but true theologically [e.g., "All beliefs God has are true"]). Participants were less accurate and slower to respond to inconsistent versus consistent statements, suggesting that the core intuitions both coexisted alongside and interfered with the acquired beliefs (Experiments 1 and 2). In Experiment 2 when responding under time pressure participants were disproportionately more likely to make errors on inconsistent versus consistent statements than when responding with no time pressure, suggesting that the resolution of interference requires cognitive resources the functioning of which decreases under cognitive load. In Experiment 3 a plausible alternative interpretation of these findings was ruled out by demonstrating that the response accuracy and time differences on consistent versus inconsistent statements occur for God-a supernatural religious entity-but not for a natural religious entity (a priest).
