This document discusses message crafting and behavioral economics. It explains that mobilizing interested stakeholders relies on positive cognitive associations with an organization, a desire for involvement, feeling part of an active community, and a clear path to impact. Behavioral economics is about low-cost decisions versus maximum return, so nudges like rewards, shares, and relevant calls to action can encourage attention, information seeking, and joining. By creating positive outcomes from involvement, social norms of support, and reducing barriers to action, communications can heighten the propensity for stakeholders to act. The role of communication is to leverage positive outcomes, community spirit, and low barriers to impact cognition and behavior, as adapted from the Theory of Planned Behavior.
