Article Citation - WoS: 18Citation - Scopus: 18Religion, parochialism and intuitive cooperation(NATURE RESEARCH, 2021-01) İşler, Ozan; Yılmaz, Onurcan; Yılmaz, Onurcan; Maule, A. John; PsychologyReligions 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 practising Christian believers were paired with either a coreligionist or an atheist and where time limits were used to increase reliance on either intuitive or deliberated decisions. We explored another dual-process account of cooperation, the self-control account (SCA), which suggests that visceral reactions tend to be selfish and that cooperation requires deliberation. We found evidence for religious parochialism but no support for SHH's prediction of intuitive cooperation. Consistent with SCA but requiring confirmation in future studies, exploratory analyses showed that religious parochialism involves decision conflict and concern for strong reciprocity and that deliberation promotes cooperation independent of religious group identity.Master Thesis Sezgisel ve Mantıksal Düşünmenin Ahlaki Faydacılığın Boyutları Üzerindeki Etkisi(2024) Almaç, Halil; Yılmaz, Onurcan; Yılmaz, Onurcan; PsychologyBu çalışmada, sezgisel ve analitik düşünmenin faydacılığın iki boyutu olan tarafsız fayda ve araçsal zarar üzerindeki etkileri incelenmiştir. Ancak, daha sonra yapılan çalışmalar (Isler & Yilmaz, 2023) akıl yürütmeye yönlendirme manipülasyonu olarak kullanılan tekniğin analitik düşünme performansını artırmadığını göstermiştir; bu da Capraro ve arkadaşlarının (2019) bulgularının yalnızca analitik düşünmenin etkilerine atfedilemeyeceğini düşündürmektedir. Ayrıca, çalışmalarında gerçek bir kontrol grubunun bulunmaması gözlemlenen etkilerin yorumlanmasını zorlaştırmaktadır. Capraro ve arkadaşlarının (2019) orijinal deney düzeneğini temel alarak, sadece onların kullandığı duygusal ve analitik düşünmeye yönlendirme manipülasyonlarını değil, aynı zamanda mevcut literatürde etkili olduğu bilinen bilişsel yanlılık eğitimini ve pasif bir kontrol grubunu da dahil ettik. Orijinal çalışmaya benzer şekilde çevrimiçi bir ABD örneklemi (N = 746) ile bir deney gerçekleştirdik. Sonuçlarımız, hem duygusal hem de analitik düşünmeye yönlendirmenin tarafsız fayda puanlarını bilişsel yanlılık eğitimi ve kontrol koşullarına kıyasla artırdığını, sadece analitik düşünmeye yönlendirmenin araçsal zarar puanlarını bu koşullara göre artırdığını ortaya koymuştur. Bununla birlikte, bilişsel yanlılık eğitimi kontrole kıyasla anlamlı bir etki göstermemiş, duygusal ve mantıksal düşünmeye yönlendirmenin bilişsel yanlılık eğitimi ve kontrole göre etkileri aynı yönde olmuştur. Analiz, Capraro ve arkadaşlarının (2019) orijinal çalışmasında olduğu gibi, yalnızca duygusal düşünme ve analitik düşünmeye yönlendirme koşullarıyla yapıldığında, ilk bulgular tekrarlanmış ve duygusal düşünmeye yönlendirmeye bağlı olarak araçsal zararda bir azalma olduğu görülmüştür. Bununla birlikte, iyi yapılandırılmış bir analitik düşünme manipülasyonu olan bilişsel yanlılık eğitiminin benzer bir etkisinin olmaması ve duygusal düşünme ve analitik düşünmeye yönlendirme manipülasyonlarının etkilerinin beklentilerin aksine aynı yönde olması, bu etkilerin yanıt yanlılıkları veya empati gibi diğer mekanizmalardan kaynaklanabileceğini düşündürmektedir. Gelecekteki çalışmalar bu etkilerin arkasındaki mekanizmaları daha kapsamlı deneylerle araştırmalıdır.Master Thesis Meta-etiksel Görüşler Gerçek Ahlaki Davranışı Yordar Mı?(2023) Albayrak, Melike; Yılmaz, Onurcan; Yılmaz, Onurcan; PsychologyLiteratürdeki mevcut çalışmalar meta-etik inançların dini inanç ve ahlaki karar alma dahil pek çok çeşitli tutum ve davranışı etkilediğini gösterse de bu çalışmaların çoğu küçük örneklem büyüklüğünden mustariptir veya kesitsel bir tasarıma sahiptir. Bildiğimiz kadarıyla hiçbir araştırma bu tür inançların insanların gerçek davranışları üzerinde uzun süreler boyunca önemli ve istikrarlı bir etkisi olup olmadığını incelememiştir. Bu çalışmada, nesnel ve öznel ahlak gibi meta-etiksel görüşlerin, ön-seçimle araştırmaya dahil edilmiş inançlı (örneğin Hıristiyanlar) ve inançlı olmayanlar (ateistler ve agnostikler) arasında 7 aylık süre zarfında prososyallik ve cezalandırıcılık gibi çeşitli ahlaki davranışları yordayıp yordamadığını araştırdık. Katılımcılar Prolific'ten seçilmiş ve Prolific tarama bilgileri kullanılarak neredeyse eşit sayıda inançlı ve inançlı olmayanlar şeklinde ayrılmıştır. Bulgular, nesnel ahlakın prososyalliği anlamlı bir şekilde yordamamasına rağmen, bir tür işbirlikçi norm yaptırımı işlevi gören ceza davranışıyla anlamlıya yakın ilişkiler sergilediklerini ortaya koymuştur. Bu etki, inançlılara kıyasla inançlı olmayanlar arasında daha güçlü olma eğilimindedir. Bununla birlikte öznel ahlak, bağımsız bir şekilde prosoyalliği veya cezalandırma davranışını yordamazken, ahlakın ilahi bir otoriteye dayandığı inancı prososyallik ile ilişkili bulunmuştur. Ön testte ölçülen bireysel farklılık değişkenlerinin düzenleyici rolüne ilişkin ek testler de anlamlı bir ilişki göstermemiştir. Bu sonuçlar, meta-etiksel inançların, özellikle ceza ile ilgili ahlaki alanlardaki davranışların önemli bir itici gücü olarak hizmet edebileceği fikrini desteklerken, prososyal davranış üzerindeki etkileri nispeten daha az belirgin olabileceğini ortaya koymuştur. Gelecekteki araştırmalar, meta-etik inançların intikamcı cezalandırma gibi farklı ceza biçimleri üzerindeki etkilerini incelemelidir.Article Citation - WoS: 3Multidimensional intuitive-analytic thinking style and its relation to moral concerns, epistemically suspect beliefs, and ideology(Cambridge Univ Press, 2023) Doğruyol, Burak; Yılmaz, Onurcan; Alper, Sinan; Yilmaz, Onurcan; PsychologyLiterature 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 if other dimensions are at play. Moreover, the presence of numerous thinking style measures, employing different terminology but conceptually overlapping, leads to confusion. To address these complexities, Newton et al. suggested the idea that individuals vary across multiple dimensions of intuitive-analytic thinking styles and distinguished thinking styles between 4 distinct types: Actively open-minded thinking, close-minded thinking, preference for effortful thinking, and preference for intuitive thinking. They proposed a new measure for this 4-factor disposition, The 4-Component Thinking Styles Questionnaire (4-CTSQ), to comprehensively capture the psychological outcomes related to thinking styles; however, no independent test exists. In the current pre-registered studies, we test the validity of 4-CTSQ for the first time beyond the original study and examine the association of the proposed measure with various factors, including morality, conspiracy beliefs, paranormal and religious beliefs, vaccine hesitancy, and ideology in an underrepresented culture, Turkiye. We found that the correlated 4-factor model of 4-CTSQ is an appropriate measure to capture individual differences based on cognitive style. The results endorse the notion that cognitive style differences are characterized by distinct structures rather than being confined to two ends of a single continuum.Article Citation - Scopus: 3Multidimensional Intuitive–analytic Thinking Style and Its Relation To Moral Concerns, Epistemically Suspect Beliefs, and Ideology(Society for Judgment and Decision making, 2023) Bayrak,F.; Doğruyol, Burak; Dogruyol,B.; Yılmaz, Onurcan; Alper,S.; Yilmaz,O.; PsychologyLiterature 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, 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 effects of eight reflection, six intuition, and two within-subjects manipulations on actual and self-reported measures of cognitive performance. Compared to the overall control, the long debiasing training was the most effective technique for increasing actual reflection scores, and the emotion induction was the most effective technique for increasing actual intuition scores. In contrast, the reason and the intuition recall, the reason induction, and the brief time delay conditions failed to achieve the intended effects. We recommend using the debiasing training, the decision justification, or the monetary incentives technique to activate reflection, and the emotion induction, the cognitive load, or the time pressure technique to activate intuition.Article Citation - WoS: 6Citation - Scopus: 7Different Types of Religiosity and Lay Intuitions About Free Will/Determinism in Turkey(Routledge Journals Taylor & Francis Ltd, 2018) Yılmaz, Onurcan; Harma, Mehmet; Harma, Mehmet; PsychologyReligiosity 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 types of religiosity and conservatism in two samples in Turkey a predominantly Muslim country (N=1690). In Study 1 a confirmatory factor analysis showed that FAD-Plus provided good fit to the data. Study 2 revealed that FW belief is not related to any of the religiosity measures (intrinsic extrinsic quest) whereas fatalistic determinism is consistently related to religiosity. The unique predictor of free will turned out to be belief in a just world. Overall these findings indicate that FW belief is not inherently related to religiosity in Turkey whereas fatalistic determinism is central to Turkish people's belief systems.Article Citation - WoS: 0Can Reflection Mitigate Covid-19 Vaccine Conspiracy Beliefs and Hesitancy(Taylor & Francis Ltd, 2025) Yılmaz, Onurcan; Sarıbay, Selahattin Adil; Ozman, Nagihan; Yilmaz, Onurcan; Isler, Ozan; Saribay, S. Adil; PsychologyObjective design:Periods of social turmoil, such as the COVID-19 pandemic, tend to amplify conspiracy beliefs, evidenced by increased vaccine hesitancy. Despite this trend, effective interventions targeting vaccine-related conspiracy beliefs remain scarce, partly due to underexplored cognitive processes. Three competing theoretical accounts offer differing predictions about the role of reflective thinking in supporting conspiracy beliefs: the Motivated Reasoning Account suggests reflection strengthens commitment to pre-existing attitudes; the Reflective Reasoning Account posits that reflection enhances belief accuracy; and the Reflective Doubt Account proposes reflection fosters general scepticism. Main outcome measures:Utilising open science practices and a validated technique to activate reflection, we conducted an experimental investigation with a diverse sample (N = 1483) segmented by vaccine attitudes. We investigated the impact of reflection on specific and generic COVID-19 conspiracy beliefs and vaccine-support behaviours across pro-vaccine, neutral, and vaccine-hesitant groups, while examining the moderating effects of scientific literacy, intellectual humility, and actively open-minded thinking. Results:The confirmatory analysis provided no direct support for the theoretical predictions. However, findings indicated that intellectual humility significantly moderated the effect of reflection, enhancing vaccine-support behaviour among participants with high intellectual humility, highlighting the complex interplay of cognitive style and prior attitudes in shaping responses to conspiracy beliefs and vaccine-support actions. Conclusion:The study highlights that while reflective thinking alone did not directly influence vaccine support behavior, its positive effect emerged among individuals with higher intellectual humility, emphasizing the importance of individual differences in shaping belief-related outcomes.Article Citation - WoS: 22Citation - Scopus: 22Reflection Increases Belief in God Through Self-Questioning Among Non-Believers(SOC Judgment & Decision Making, 2019) Yılmaz, Onurcan; Yılmaz, Onurcan; İşler, Ozan; PsychologyThe 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 the intuitive religious belief hypothesis. Many of the previous studies are underpowered to detect small effects, and it is not clear whether the cognitive process manipulations used in these failed attempts worked as intended. We investigated the influence of intuitive and reflective thought on belief in God in two large-scale preregistered experiments (N = 1,602), using well-established cognitive manipulations (i.e., time-pressure with incentives for compliance) and alternative elicitation methods (between and within-subject designs). Against our initial hypothesis based on the literature, the experiments provide first suggestive then confirmatory evidence for the reflective religious belief hypothesis. Exploratory examination of the data suggests that reflection increases doubts about beliefs held regarding God's existence. Reflective doubt exists primarily among non-believers, resulting in an overall increase in belief in God when deciding reflectively.Article Citation - WoS: 134Citation - Scopus: 132Psychological Correlates of Covid-19 Conspiracy Beliefs and Preventive Measures: Evidence From Turkey(Springer, 2020) Alper, Sinan; Yılmaz, Onurcan; Bayrak, Fatih; Yılmaz, Onurcan; PsychologyCOVID-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; (2) whether such conspiracy beliefs are related to the level of preventive measures; and (3) other individual differences that might be related to the preventive measures. Higher faith in intuition, uncertainty avoidance, impulsivity, generic conspiracy beliefs, religiosity, and right-wing ideology, and a lower level of cognitive reflection were associated with a higher level of belief in COVID-19 conspiracy theories. There was no association between COVID-19 conspiracy beliefs and preventive measures while perceived risk was positively and impulsivity negatively correlated with preventive measures. We discuss the implications and directions for future research.
