Visual mapping for better decisions

Mikko Arevuo presents research on how causal mapping— a structured visual mapping technique— improves the quality of group decision-making processes. Drawing on seven years of empirical research across executives, medical practitioners, military officers, and students, he explains how visual mapping increases constructive debate, reduces bias, and strengthens decision acceptance. The session explores both the cognitive and behavioural dynamics that unfold when groups think visually together. [00:05:28] The Problem: 50% of Strategic Decisions Fail Mikko introduces the core challenge: many strategic decisions fail, often because of weaknesses in the decision-making process rather than flawed intentions. [00:08:02] Five Critical Factors in Group Decision Making He outlines key dynamics: cognitive conflict (healthy debate), affective conflict (personal tension), groupthink, attribution biases, and risk escalation. [00:11:21] What Is Causal Mapping? Causal mapping is introduced as a note-and-arrow visual structure linking issues, actions, and consequences through causal relationships. [00:13:31] Moving Beyond Linear Thinking Unlike brainstorming or linear discussion, causal mapping visually represents interconnected options and both positive and negative consequences. [00:15:37] Research Design: Observing Real Decision Groups Mikko describes studies involving doctors, executives, military officers, and students using whiteboards and post-it notes to build maps collaboratively. [00:16:45] The Map as an Epistemic Object The visual map becomes a shared knowledge object that captures collective understanding and shifts attention away from personalities toward the problem. [00:18:01] The “Safety Net” Effect Posting ideas onto the board allows participants to express views without defending them face-to-face, reducing interpersonal tension. [00:19:09] The “Shock Absorber” Effect When debate intensifies, frustration is directed at the board rather than individuals, preventing affective (personal) conflict. [00:22:45] Embodied Cognition and Physical Engagement Standing, huddling around the board, and physically interacting with the map changes group dynamics compared to sitting around a table. [00:23:56] Increasing Cognitive Conflict While Reducing Bias Structured visual debate increases constructive disagreement and reduces escalation of commitment, optimism bias, and groupthink. [00:26:19] The IKEA Effect and Decision Acceptance Because participants co-construct the map, they take ownership of the outcome and show stronger commitment to implementation. [00:28:22] Implications and Ongoing Research Mikko highlights continued research into mapping, embodied cognition, and decision quality across diverse organisational settings.
