This work employs gamification to design an experiential exercise, in the form of a picture-based crossword puzzle, to facilitate holistic learning around common biases and errors influencing individual decision-making. In a roughly 75-minute experiential exercise, participants will be exposed to two rounds of picture-based cues, reflecting the underlined concept and/or practical application of ten major cognitive biases and seven perceptual errors. The participants are required to identify the associated bias or error using these clues in order to complete the crossword puzzle provided to them. Doing so, the exercise aims to stimulate participants’ comprehension and retention of these important concepts along with boosting their levels of in-class engagement. The exercise can thus be used as an active learning tool in courses such as organizational behavior, psychology, strategic management, negotiation skills, leadership, and marketing. A follow up discussion on cognitive biases and perceptual errors is provided for classroom teaching.
