Psychologists Dr. Jiaying Zhao and Dr. Elizabeth Dunn propose that positive emotions, particularly joy, are far more effective than guilt or shame for establishing lasting habits, including climate action. Their book, "Leave the Lights On," explains that negative reinforcement often fails to solidify new behaviors. Instead, operant conditioning shows that actions making us feel better are more likely to be repeated. They suggest framing changes as "do more of" rather than "stop doing," like "eat more plants," which also boosts happiness. This emotional intelligence approach involves engineering positive feelings into habits. Key steps include focusing on additions, recognizing emotional payoffs, reducing friction, and sharing successes to make habits self-sustaining.
