Dynamic Norms and Food Choice: Reflections on a Failure of Minority Norm Information to Influence Motivation to Reduce Meat Consumption

Recent research in the US shows the potential of providing information about minority norms that are increasing on positively influencing interest and engagement in desired behaviours. Although these are promising findings, there is little published research replicating or testing this effect outside the US. The study reported here is a direct replication of Sparkman and Walton’s (2017) research. We explored the effects of different kinds of normative information, particularly information about increasing (referred to as ‘dynamic’ or ‘trending’) minority norms, on interest in reducing meat consumption, attitudes toward reducing meat consumption, intentions to reduce meat consumption, and expectations to do so. Following pilot work ( n = 197), we used a double-blind online study with three conditions: dynamic norm ( n = 276), static norm ( n = 284), and no norm ( n = 286). The sample consisted of British people, with ages ranging from 18 to 79 ( M age = 37.21, SD age = 13.58; 56.38% female). There was no effect of dynamic norm information on any outcomes, including predictions about future meat consumption norms. Exploratory analyses suggest that political position and gender were associated with meat consumption outcomes. The findings are discussed in relation to conditions under which dynamic normative information may be successful in influencing motivation to engage in desired behaviours, and to possible improvements in research design.
