Insights into Group-Level Cooperative Versus Opportunistic Behaviors: Using an Educational Inter-Group Trust Simulation for Research

Experiential learning through simulations offers a unique but often underutilized opportunity to bridge the gap between pedagogy and empirical research. This study addresses this gap by transforming the Pemberton’s Dilemma simulation from a classroom exercise into a quantitative, empirical research project to investigate the dynamics of trust, cooperation, and opportunistic behavior. To address questions related to such trust interactions, the simulation was modified to include variable payout stakes, restricted and permitted communication phases, and an additional surprise round to measure long-term trust reputation effects. From 2017 through 2025, data was gathered from a convenience sample of 611 students from a large public university in the Northwestern United States. Results indicate that non-trusting behavior has a significantly greater mirroring effect than trusting behavior and that higher financial stakes frequently prime groups toward opportunistic hedging. While opportunistic strategies yielded greater short-term gains, longitudinal analysis revealed a significant positive correlation between consistent trust and monetary outcomes. Furthermore, the surprise round data confirmed that prior trust violations severely diminished cooperation and earnings in the future unknown round. The study supports the benefits of integrating quantitative research into pedagogical experiential tools to advance scholarly understanding (in this case of trust dynamics and the vital role of transparent communication and sustainability-compatible strategies), enhance student learning, and to provide data-driven recommendations for organizations.
