Introduction
I'm an associate professor of psychology at Kadir Has University, Istanbul, and I currently lead the MINT lab ((www.moralintuitionslab.com) — a collaborative interdisciplinary laboratory bringing together my diverse, but integrated, research foci covering the psychology of morality, political psychology, cognitive science of religion, and decision-making areas. My research mainly focuses on dual-process accounts of moral judgment and behavior.

Two central debates within Moral Foundations Theory concern (1) which moral foundations are core and (2) how conflict between ideological camps stemming from valuing different moral foundations can be resolved. Previous studies have attempted to answer the first question by imposing cognitive load on participants to direct them toward intuitive and...
Motivated by the dual-process model of the mind, recent research has tested the relationship between cognitive variables and sociopolitical attitudes. There are reasons to believe that religiosity and conservatism may be differentially predicted by analytic cognitive style (ACS) and cognitive ability (CA), respectively. We collected data with three...
Previous research revealed that inducing an intuitive thinking style led people to adopt more conservative social and economic attitudes. No prior study, however, has shown a causal effect of analytic cognitive style (ACS) on political conservatism. It is also not clear whether these cognitive-style manipulations influence stable or contextualized...
People’s large-scale cooperation with genetically unrelated people is widely assumed to lie beyond the scope of standard evolutionary mechanisms like kin selection and reciprocal altruism and to require mechanisms specific to human sociality. The emergence of the idea of being monitored by supernatural agents who can punish social norm violations h...
The relation between religious and moral thought has been difficult to unravel because of the multifaceted nature of both religion and morality. We chose to study the belief dimension of religion and the meta-ethics dimension of morality and investigated the relation between God-related thoughts and objectivist/subjectivist morality in three studie...
Understanding our cognitive and behavioral reactions to large-scale collective problems involving health and resource scarcity threats, such as the COVID-19 pandemic, helps us be better prepared for future collective threats. However, existing studies on these threats tend to be restricted to correlational data, partly due to a lack of reliable exp...
Despite the considerable attention it has received, Moral Foundations Theory (MFT) remains open to criticisms regarding failure to conceptualize the moral domain. MFT was revised in response to these criticisms, along with its measurement tool, the Moral Foundations Questionnaire (MFQ-2). However, the validity of this revised theoretical structure...
There is considerable uncertainty about how thinking style relates to religious belief. In the present study, we tested three hypotheses about relationships between reflective thinking, intuitive thinking (both measured using the Cognitive Reflection Test; CRT) and belief in God or gods (BiG) across 19 culturally and geographically diverse countrie...
Literature highlights the distinction between intuitive and analytic thinking as a prominent cognitive style distinction, leading to the proposal of various theories within the framework of the dual process model. However, it remains unclear whether individuals differ in their thinking styles along a single dimension, from intuitive to analytic, or...
Research on cooperation between groups tends to consider a single social identity at a time. However, individuals naturally share group membership in one social category (e.g., religious belief) while diverging in membership to others (e.g., political ideology). Here, we test the effects of mixed-group membership on actual cooperative behavior rela...
Belief in various types of Epistemically Suspect Beliefs (ESB; conspiracy, paranormal, and pseudoscience beliefs) is known to correlate strongly with one another. In the current research, we developed a Fictitious Epistemically Suspect Beliefs (FESB) scale, consisting of entirely new and fabricated conspiracy, paranormal, and pseudoscience claims....
The volume Divided: Open-Mindedness and Dogmatism in a Polarized World provides a current scientific understanding of open-mindedness and dogmatism, illuminates the nature and causes of polarization, and provides clues regarding how one might attempt to reduce pernicious forms of polarization. To do so, this volume brings together a diverse group o...
One of the most prominent correlates of trust in science and scientists is education level, possibly because educated individuals have higher levels of science knowledge and thinking ability, suggesting that trusting science and scientists relies more on reflective thinking abilities. However, it is relatively more reasonable for highly educated in...
In 2012, two independent groups simultaneously demonstrated that intuitive mindset enhances belief in God. However, there is now some mixed evidence on both the effectiveness of manipulations used in these studies and the effect of mindset manipulation on belief in God. Thus, this proposal attempted to replicate one of those experiments (Shenhav, R...
Manipulations for activating reflective thinking, although regularly used in the literature, have not previously been systematically compared. There are growing concerns about the effectiveness of these methods as well as increasing demand for them. Here, we study five promising reflection manipulations using an objective performance measure — the...
The structure of moral judgment and its ontogenetic and phylogenetic origins have been empirically studied since the emergence of psychology as a science. Although an early influential perspective emerged with Piaget, the first systematic theory, which was the subject of a great deal of empirical research, was proposed by Kohlberg. Kohlberg’s theor...
Experiments comparing intuitive and reflective decisions provide insights into the cognitive foundations of human behavior. However, the relative strengths and weaknesses of the frequently used experimental techniques for activating intuition and reflection remain unknown. In a large-scale preregistered online experiment (N = 3667), we compared the...

The relation between religiosity and well-being is one of the most researched topics in the psychology of religion, yet the directionality and robustness of the effect remains debated. Here, we adopted a many-analysts approach to assess the robustness of this relation based on a new cross-cultural dataset (N = 10, 535 participants from 24 countries...
At the beginning of 2020, COVID-19 became a global problem. Despite all the efforts to emphasize the relevance of preventive measures, not everyone adhered to them. Thus, learning more about the characteristics determining attitudinal and behavioral responses to the pandemic is crucial to improving future interventions. In this study, we applied ma...
The study of moral judgements often centres on moral dilemmas in which options consistent with deontological perspectives (that is, emphasizing rules, individual rights and duties) are in conflict with options consistent with utilitarian judgements (that is, following the greater good based on consequences). Greene et al. (2009) showed that psychol...

However, the relative strengths and weaknesses of the frequently used experimental techniques for activating intuition and reflection remain unknown.

Actively Open-Minded Thinking (AOT) is a set of standards for rational thinking. Because the thinking of citizens and officials affects political decisions, good thinking is a moral virtue, like honesty. AOT standards have two functions: people try to follow their own standards; and they apply these standards to the evaluation of the thinking of ot...

Changing collective behaviour and supporting non-pharmaceutical interventions is an important component in mitigating virus transmission during a pandemic. In a large international collaboration (Study 1, N = 49,968 across 67 countries), we investigated self-reported factors associated with public health behaviours (e.g., spatial distancing and str...
Previous research suggests that conservatives (right-wingers) tend to show more negativity bias than liberals (left-wingers) in several tasks. However, the majority of these studies are based on correlational findings and do not provide information on the cognitive underpinnings of this tendency. The current research investigated whether intuition...
COVID-19 pandemic has led to popular conspiracy theories regarding its origins and widespread concern over the level of compliance with preventive measures. In the current preregistered research, we recruited 1088 Turkish participants and investigated (a) individual differences associated with COVID-19 conspiracy beliefs; (b) whether such conspirac...
I discuss recent research suggesting that individual differences in cognitive style give rise to and explain religious and related supernatural and paranormal beliefs. To do so, I illustrate intuitive cognitive biases (e.g., anthropomorphism) underlying these beliefs and then review the accumulated evidence indicating that non-believers are more op...
We used composite face images perceived to have different levels of Dark Triad personality traits (narcissism, psychopathy, and Machiavellianism) and asked participants to predict these target individuals' religious and political identities. In Study 1 (N = 550), Turkish participants rated faces with higher levels of perceived Dark Triad traits as...
Sonuçları tüm insanları ve çevreyi etkilemesine rağmen bilimsel olarak gerçekliği tespit edilmiş küresel ısınma gibi sorunların varlığı insanların bir kısmı tarafından reddedilmektedir. Bu konudaki alanyazına göre bilimsel sorunların varlığını reddetme ideolojik değerlendirmelerin etkisiyle şekillenebilmektedir. Cambpell ve Kay (2014) tarafından ge...
Religions promote cooperation, but they can also be divisive. Is religious cooperation intuitively parochial against atheists? Evidence supporting the social heuristics hypothesis (SHH) suggests that cooperation is intuitive, independent of religious group identity. We tested this prediction in a one-shot prisoner’s dilemma game, where 1,280 practi...
How can we maximize what is learned from a replication study? In the creative destruction approach to replication, the original hypothesis is compared not only to the null hypothesis, but also to predictions derived from multiple alternative theoretical accounts of the phenomenon. To this end, new populations and measures are included in the design...

The theory of morality as cooperation (MAC) argues that there are seven distinct and evolved universal moral foundations. Curry, Chesters, and Van Lissa (2019) developed a scale to test this theoretical approach and showed that the Relevance subscale of the MAC questionnaire (MAC-Q) fits data well, unlike the Judgment and full-form. However, an ind...
To follow trends in Turkish public opinion regarding past and current events as well as future expectations. Survey conducted with 1000 people, 18 years and older, in 26 provinces (İstanbul, Ankara, Konya, Bursa, Kocaeli, İzmir, Aydın, Manisa, Tekirdağ,

Some of the recent studies suggested that people can make accurate inferences about the level of the Big Five and the Dark Triad personality traits in strangers by only looking at their faces. However, later findings provided only partial support and the evidence is mixed regarding which traits can be accurately inferred from faces. In the current...
Two opposing views define the debate on the moral principles underlying human behavior. One side argues a central role for five moral foundations (care, fairness, loyalty, authority, sanctity), while the other argues that two of these (care, fairness) capture the essence of human moral concerns. In an experiment comparing these two views, Wright an...

Recent correlational and experimental studies demonstrate that differences in people’s thinking styles have an impact on their political attitudes. Whereas the dual process model of mind relates social conservative attitudes to intuitive (vs. analytical) thinking style, construal level theory links abstract (i.e., concrete) thinking style to politi...
COVID-19 pandemic has led to popular conspiracy theories regarding its origins and widespread concern over the level of compliance with preventive measures. In the current preregistered research, we recruited 1,088 Turkish participants and investigated (a) individual differences associated with COVID-19 conspiracy beliefs; (2) whether such conspira...
Previous studies consistently showed that analytic cognitive style (ACS) is negatively correlated with social conservatism, but there are mixed findings concerning its relation with economic conservatism. Most tests have relied on a unidimensional (liberal-conservative) operationalization of political orientation. Libertarians tend not only to iden...

Although the effect of religious belief on morally relevant behavior is well demonstrated, the reverse influence is less known. In this research, we examined the influence of morality on religious belief. In the first study, we used two samples from Turkey and the United States, and specifically tested the hypothesis that intergroup tolerance predi...
In the first half of the twentieth century, Wittgenstein claimed that philosophy is ended in his Tractatus Logico-Philosophicus and that he found the solution to all questions previously asked in philosophy. He later traveled the world and changed his mind in the early stages of his work, especially after reading Kierkegaard and Nietzsche. Psycholo...
The dual-process model of the mind predicts that religious belief will be stronger for intuitive decisions, whereas reflective thinking will lead to religious disbelief (i.e., the intuitive religious belief hypothesis). While early research found intuition to promote and reflection to weaken belief in God, more recent attempts found no evidence for...
We analyzed the content of “Friday Khutbas” delivered in Turkish mosques between January 2001 and December 2018 to test the prediction of moral foundations theory (MFT) literature that threat salience would lead to an increased endorsement of binding moral foundations. As societal‐level indicators of threat, we examined (1) historical data on the n...
Although numerous models attempted to explain the nature of moral judgment, moral foundations theory (MFT) led to a paradigmatic change in this field by proposing pluralist "moralities" (care, fairness, loyalty, authority, sanctity). The five-factor structure of MFT is thought to be universal and rooted in the evolutionary past but the evidence is...
Recent research suggests that experimentally inducing an abstract (vs. a concrete) mind-set enhances political sophistication by increasing the consistency in political attitudes; it also enhances individualizing moral foundations and decreases binding moral foundations. However, the evidence is mixed regarding whether abstract mind-set increases o...
Much research on moral judgment is centered on moral dilemmas in which deontological perspectives (i.e., emphasizing rules, individual rights and duties) are in conflict with utilitarian judgements (i.e., following the greater good defined through consequences). A central finding of this field Greene et al. showed that psychological and situational...
Claims of universality for Moral Foundations Theory (MFT) require extensive cross-cultural validation. The present study aims to (1) develop Turkish versions of three instruments used to research MFT (MFQ, MFQL, MSQ); (2) assess the psychometric properties of the Turkish instruments; (3) test the assumptions of the theory against findings from the...
While previous studies reveal mixed findings on the relationship between analytic cognitive style (ACS) and right-wing (conservative) political orientation, the correlation is generally negative. However, most of these studies are based on Western, educated, industrialized, rich, and democratic (WEIRD) societies, and it is not clear whether this re...
There has been extensive research on how the Big Five personality traits are related to political orientation and endorsement of moral foundations. However, recent findings suggest that these relationships may not be cross-culturally stable. We argue that how much a culture is WEIRD (Western, educated, industrialized, rich, and democratic) could mo...

Most studies on mate selection criteria have focused on women and rely on Western samples. In the present study, we tested both women's and men's mate preferences from evolutionary and cultural perspectives in a large, mostly Muslim sample (N = 1114). Results showed that (1) the relation between women's families’ income level and the income level t...
Although religiosity fosters some antisocial behaviors (e.g., support for suicide attacks), it is well-known that it also enhances in-group cooperation and prosociality (e.g., donating to charity). Supernatural punishment hypothesis suggests that the fear of punishment from an invisible, potent, and powerful supernatural agent can keep everyone in...

Bu sayıda etnik ve ulusal kimlikler, vatandaşlık, kolektif eylem, değer yönelimleri, göçmenlere karşı tu- tumlar, sosyal temsiller ve AB’ye yönelik tutumlar gibi konularda görgül...
Moral foundations theory (MFT), while inspiring much empirical work, has been the target of both methodological and theoretical criticism. One important criticism of MFT is that, in its attempt to explain variability in political ideology, it only repackages the core motives (resistance to change and opposition to equality) and does not actually pr...
We aimed to understand which kind of arguments can play an important role for moral decision making. Specifically, first of all, we tested arguments of Kahane and Greene. In this way, we have examined whether utilitarianism is related to psychopathic tendencies or analytical thinking. Additionally, we also investigated whether people make moral dec...
Although lay notions in normative ethics have previously been investigated within the framework of the dual-process interpretation of the terror management theory (TMT), meta-ethical beliefs (subjective vs. objective morality) have not been previously investigated within the same framework. In the present research, we primed mortality salience, sho...
Bu çalışmanın temel amacı, Türkiye’de yaşayan bir katılımcı grubundan elde edilen değerlerden yola çıkarak yerel bir değerler ölçeği oluşturmak ve bu değerlerin politik/dini yönelime ek olarak Schwartz’ın değer kategorileriyle ilişkisini incelemektir. Araştırmanın ilk aşamasında, açık uçlu cevap yöntemiyle 395 katılımcıdan en önem verdikleri değerl...
Religiosity has been found to be positively associated with belief in free will (FW) in the Western world. In the Muslim world, however, religiosity exhibits several characteristics that set it apart from the Western world, including an overemphasis on fate or divine predestination. We, therefore, investigated FW/determinism beliefs and different t...
In recent years, there has been increasing research attention to cognitive style differences between liberals and conservatives. While some studies have found a negative relation between conservatism and analytic thinking tendency, others have not observed such a relation. None of these studies has measured the core motives underlying conservative...
As a possible Hilbert question in the scientific study of religion, this article tries to explicate one specific relation between religion and morality, viz., whether religion is necessary for morality. More specifically: How does the introduction of religion transform morality? The article operationalizes morality as normative and meta-ethical jud...
Analytic cognitive style (ACS) has usually been found to be negatively correlated with religiosity. Several recent studies, however, challenged this finding claiming, for example, that the presumed association is an artifact of the order of presentation of the ACS and religiosity measures or that ACS might be differently related to different types...
The “conservatism as motivated social cognition” approach posits two core ideological motives underlying political conservatism across cultures. However, there is a scarcity of tests from non‐Western cultures, and much research has failed to distinguish between social and economic conservatism. Using a relatively large undergraduate sample from a n...
The psychological correlates of utilitarian choices in sacrificial moral dilemmas are contentious. In the literature, some research (Greene, et al., 2001) suggested that utilitarianism requires analytic thinking while other research (Kahane et al., 2015) showed that utilitarianism is correlated with psychopathy. In the present research, we looked a...
ABSTRACT
In the Western literature, political ideology has recently been conceptualized with the help of two, presumably culture-free dimensions labeled “opposition to equality” and “resistance to change.” In the present research, we investigated whether these two dimensions can be used to construct a valid and reliable measure of political ideolog...

The present research investigated the reason for mixed evidence concerning the relationship between analytic cognitive style (ACS) and political orientation in previous research. Most past research operationalized ACS with the Cognitive Reflection Test (CRT), which has been criticized as relying heavily on numeracy skills, and operationalized polit...
