Testing the Power of Game Lessons: The Effects of Art and Narrative on Reducing Cognitive Biases

Educational games have proliferated, but questions remain about the effectiveness at teaching both in the shortand long-term. Also unclear is whether particular game features have positive effects on learning. To examine these issues, this paper describes a controlled experiment using an educational game that was professionally developed to teach about cognitive biases in decision making (Fundamental Attribution Error, Confirmation Bias, and Bias Blind Spot). This experiment examined the effects of game art and narrative on learning and compared the game conditions to a training video. Effects were measured immediately after the stimuli were given and then again eight weeks later. Results indicate that the educational game outperforms the training video immediately after exposure and that there are significant retention effects. Art and narrative were not significantly related to learning with the exception that minimal art game had a significant positive relationship with mitigating Bias Blind Spot at immediate post-test.
