This work package investigates collective wisdom in two kinds of "crowd": groups of backcounty skiers making judgments about avalanche risks and expert panels assessing the avalanche danger level of different regions in Switzerland. The research methods ninclude mathematical analysis and computer modelling, with extensive use of data collected among skiers and forecasters. The collective judgment methods that are investigated include voting and deliberation among group members.
