Reduced Meat Consumption: from Multicriteria Argument Modelling to Agent-Based Social Simulation

A second nutrition transition seems to be emerging towards more plant-based diets, curbing meat consumption in developed countries at the beginning of 21st century. This shift suggests that rational arguments tend influence an increasing number individuals adopt vegetarian diets. work aimed understand and simulate impact different types messages on choice change food diets individual level, diffusion opinions collective level. It provided two results: (1) a network around is modelled using abstract argumentation approach. Each argument, formalized by node, was connected with other arrows, thus formalizing relationships between arguments. methodology made it possible formalize argument about identify importance health compared ethical or also identified key as result their high centrality being challenged challenging The results constructing this suggested any controversy surrounding will polarized such health. Even though few appeared our network, concerning necessity not animal products for humans were indirectly choices diets; (2) agent-based simulation social practices then introduced. purpose capture balance vs. meat-based contributes modelling consumer exploring values external influences pressure, communication campaigns sanitary, environmental crises.
