Trust is Critical in Military Contexts • US military needs to cultivate and accurately assess trust and credibility in diverse cultural and religious contexts • Trust in multicultural teams where people are truly vulnerable to actions of other team members • Religion and culture may affect trust • US, Singapore, and Israel • Individualism-Collectivism • Tightness-Looseness • Religious Ingroup-Outgroup Identities • Supernatural Monitoring • Religious Costly Signaling
Costly Signaling and Trust • Religion often involves costly signals of commitment to the ingroup which promote trust (Sosis & Alcorta, 2003) – elaborate rituals, charity, sacrifices, circumcision, dietary restrictions, etc. • Does the presence of ingroup religious signals increase trust? • Does the presence of outgroup costly signals decrease trust?
Friending on Facebook • 393 Christian undergraduates (308 Protestant, 85 Catholic) • 153 male, 240 female • Manipulated – religious group – beliefs about God – costly signaling
Trust Scale, α =. 82 • Do you think this person is trustworthy? • Would you trust this person with a sensitive secret? • Would you lend this person money and expect to get it back? • Do you think this person has the ability to be trustworthy? • Do you think this person is benevolent? • Do you think this person has integrity?

Challenge Versus Threat Physiology Emotional and physiological responses to a situation are triggered by cognitive appraisal of the event as a threat or a challenge. Challenge: efficient mobilization of cardiac resources. Blood vessel dilation results in decreased vascular resistance. Threat: inefficient mobilization of cardiac resources. Either no change or an increase in vascular resistance, resulting in increased blood pressure. 13

Summary • Religion, often an assumed stumbling block to building trust, can build trust in volatile world environments – People can find outgroup members trustworthy – Costly signaling promotes trust within and across groups, seemingly related to integrity – Counter-intuitive effects of cross-group signaling? • Similarity but some nuance across religious groups (Christians, Muslims) • EEG predictor of trust decisions 22

Project Summary Research Objectives: Technical Approach: • Elucidate the cultural and religious factors that promote or hinder trustworthiness • Experimental social psychology • Examine the neural (EEG) and physiological correlates of trust • Cross-cultural and –religion research • EEG techniques • Autonomic physiology assessment • Refine theory, measurement on factors of trustworthiness Key Findings: • People can find outgroup members trustworthy • Costly signaling promotes trust within and across groups, surprisingly – related to integrity Benefits to the wider academic or Do.
