Our lives are governed by informal and formal systems that maintain order and signal what is right and wrong.

Principles & Strategies

Mandate behavior

  • Enact mandates that require or encourage certain behaviors

Prohibit behavior

  • Enact prohibitions that limit or forbid certain behaviors


People have different responses to rules across contexts. Be sure to learn about how different rules are understood by your target audience. Bans on behavior can also be very difficult to monitor or enforce, especially for behaviors done in private.
