The Starfish Technique is used to brainstorm sequences of behaviors that could lead to a target behavior. It involves drawing "legs" radiating from a central starfish shape to map out different pathways. An example starfish maps out ways someone might end up eating more vegetables, through steps like seeing a cooking show, getting invited to a friend's house where vegetables are served, writing down recipes, buying ingredients, and preparing the meal. The key is to identify intermediary behaviors that could cascade into the desired outcome.
